 McLaren F1, 1993

The McLaren F1 is a sports car designed and manufactured by Gordon Murray and McLaren Automotive. On March 31, 1998, it set the record for the fastest production car in the world, 240 mph (391 km/h). As of April 2009, the McLaren F1 is succeeded by three faster cars in sheer top speed, but is still the fastest naturally aspirated production car.

Engine
Gordon Murray insisted that the engine for this car be naturally aspirated to increase reliability and driver control. Turbochargers and superchargers increase power but they increase complexity and can decrease reliability as well as introducing an additional aspect of latency and loss of feedback, the ability of the driver to maintain maximum control of the engine is thus decreased. Murray initially approached Honda for an NA powerplant with 550 bhp (410 kW; 560 PS), 600 mm (23.6 in) block length and a total weight of 250 kg (551 lb), it should be derived from the Formula One powerplant in the then-dominating McLaren/Honda cars.

When Honda refused, Isuzu, then planning an entry into Formula One, had a 3.5 V12 engine being tested in a Lotus chassis. The company was very interested in having the engine fitted into the McLaren F1. However, the designers wanted an engine with a proven design and a racing pedigree.

In the end BMW took an interest, and the motorsport division BMW M headed by engine expert Paul Rosche designed and built Murray a custom-designed 6.1 L (6064 cc) 60-degree V12 engine, which was 14% more powerful than specified and 16 kg (35 lb) heavier - despite being based on the original specifications of 550 bhp (410 kW; 560 PS), 600 mm (23.6 in) block length and total weight of 250 kilograms (550 lb).

The final result is a custom-built 6.1 L (6064 cc) 60-degree V12 with an aluminium alloy block and head, 86 mm (3.4 in) x 87 mm (3.4 in) bore/stroke, quad overhead camshafts for maximum flexibility of control over the four valves per cylinder and a chain drive for the camshafts for maximum reliability, the engine is dry sump. At 266 kg (586 lb), the resulting engine was slightly heavier than Murray's original maximum specification weight of 250 kg (551 lb) but was also considerably more powerful than he had specified. The bespoke engineered engine for the McLaren F1 is called the BMW S70/2.

The carbon fibre body panels and monocoque required significant heat insulation in the engine compartment, so Murray's solution was to line the engine bay with a highly efficient heat-reflector: gold foil. Approximately 25 g (0.8 ounce) of gold was used in each car.

The road version used a compression ratio of 11:1 to produce 627 hp (468 kW; 636 PS) at 7400 rpm—considerably more than Murray's specification of 550 horsepower (404 kW). Torque output of 480 ft·lb (651 N·m) at 5600 rpm. The engine has a redline rev limiter set at 7500 rpm.

In contrast to raw engine power, a car's power-to-weight ratio is a better method of quantifying acceleration performance than the peak output of the vehicle's powerplant. The standard McLaren F1 achieves 550 hp/ton (403 kW/tonne), or just 3.6 lb/hp. Compare with the Ferrari Enzo at 434 hp/ton (314 kW/tonne) (4.6 lb/hp), the Bugatti Veyron at 530.2 hp/ton (395 kW/tonne) (4.1 lb/hp), and the SSC Ultimate Aero TT with an alleged 1003 hp/ton (747.9 kW/tonne) (2 lb/hp).

The cam carriers, covers, oil sump, dry sump, and housings for the camshaft control are made of magnesium castings. The intake control features twelve individual butterfly valves and the exhaust system has four Inconel catalysts with individual Lambda-Sond controls. The camshafts are continuously variable for increased performance, using a system very closely based on BMW's VANOS variable timing system for the BMW M3; it is a hydraulically-actuated phasing mechanism which retards the inlet cam relative to the exhaust cam at low revs, which reduces the valve overlap and provides for increased idle stability and increased low-speed torque. At higher RPM the valve overlap is increased by computer control to 42 degrees (compare 25 degrees on the M3) for increased airflow into the cylinders and thus increased performance.

To allow the fuel to atomise fully the engine uses two Lucas injectors per cylinder, with the first injector located close to the inlet valve - operating at low engine RPM - while the second is located higher up the inlet tract - operating at higher RPM. The dynamic transition between the two devices is controlled by the engine computer.

Each cylinder has its own miniature ignition coil. The closed-loop fuel injection is sequential. The engine has no knock sensor as the predicted combustion conditions would not cause this to be a problem. The pistons are forged in aluminium.

Every cylinder bore has a nikasil coating giving it a high degree of wear resistance.
From 1998 to 2000, the Le Mans-winning BMW V12 LMR sports car used a similar S70/2 engine.

The engine was given a short development time, causing the BMW design team to use only trusted technology from prior design and implementation experience. The engine does not use titanium valves or connecting rods. Variable intake geometry was considered but rejected on grounds of unnecessary complication.
As for fuel consumption, the engine uses on average 15.2 mpg, at worst 9.3 mpg and at best 23.4 mpg.

Chassis and body
The McLaren F1 was the first production road car to use a complete carbon fiber reinforced plastic (CFRP) monocoque chassis structure. Aluminium and magnesium was used for attachment points for the suspension system, inserted directly into the CFRP.
The car features a central driving position - the driver's seat is located in the middle, ahead of the fuel tank and ahead of the engine, with a passenger seat slightly behind and on either side. The doors on the vehicle move up and out when opened, and are thus of the type butterfly doors.

The engine produces high temperatures under full application and thus cause a high temperature variation in the engine bay from no operation to normal and full operation. CFRP becomes mechanically stressed over time from high heat transfer effects and thus the engine bay was decided to not be constructed from CFRP.

Aerodynamics
The overall drag coefficient on the standard McLaren F1 is 0.32, compared with 0.36 for the faster Bugatti Veyron, and 0.357 for the current holder of the fastest car world record (as of 2008) - the SSC Ultimate Aero TT (in terms of top speed). The vehicle's frontal area is 1.79 square meters and the total Cx is 0.57. Due to the fact that the machine features active aerodynamics these are the figures presented in the most streamlined configuration.

Suspension
Steve Randle who was the car's dynamicist was appointed responsible for the design of the suspension system of the McLaren F1 machine. It was decided that the ride should be comfortable yet performance oriented, however not as stiff and low as that of a true track machine, as that would imply reduction in practical use and comfort as well as increasing noise and vibration, which would be a contradictory design choice in relation to the former set premise - the goal of creating the ultimate road car.

From scratch the design of the McLaren F1 vehicle had strong focus on centering the mass of the car as near the middle as possible by extensive manipulation of placement of i.a. the engine, fuel and driver, allowing for a low polar moment of inertia in yaw. The McLaren F1 has 42% of its weight at the front and 58% at the rear, this figure changes less than 1% with the fuel load.

The distance between the mass centroid of the car and the suspension roll centre were designed to be the same front and rear to avoid unwanted weight transfer effects. Computer controlled dynamic suspension were considered but not applied due to the inherent increase in weight, increased complexity and loss of predictability of the vehicle.

Damper and spring specifications: 90 mm (3.5 in) bump, 80 mm (3.1 in) rebound with bounce frequency at 1.43 Hz at front and 1.80 Hz at the rear, despite being sports oriented these figures imply the rather soft ride and will inherently decrease track performance, but again, the McLaren F1 is not in concept nor implementation a track machine. As can be seen from the McLaren F1 LM, McLaren F1 GTR et al., the track performance potential is much higher than that in the stock McLaren F1 due to fact that car should be comfortable and usable in everyday conditions.

The suspension is a double wishbone system with an interesting design, i.a. that longitudinal wheel compliance is included without loss of wheel control, which allows the wheel to travel backwards when it hits a bump - increasing the comfort of the ride.

Castor wind-off at the front during braking is handled by McLaren's proprietary Ground Plane Shear Centre - the wishbones on either side in the subframe are fixed in rigid plane bearings and connected to the body by four independent bushes which are 25 times more stiff radially than axially. This solution provides for a castor wind-off measured to 1.02 degrees per G of braking deceleration. Compare the Honda NSX at 2.91 degrees per G, the Porsche 928 S at 3.60 degrees per G and the Jaguar XJ6 at 4.30 degrees per G respectively. The difference in toe and camber values are also of very small under lateral force application. Inclined Shear Axis is used at the rear of the machine provides measurements of 0.04 degrees per G of change in toe-in under braking and 0.08 degrees per G of toe-out under traction.

When developing the suspension system the facility of electro-hydraulic kinematics and compliance at Anthony Best Dynamics was employed to measure the performance of the suspension on a Jaguar XL16, a Porsche 928S and a Honda NSX to use as references.
Steering knuckles and the top wishbone/bell crank are also specially manufactured in an aluminium alloy. The wishbones are machined from a solid aluminium alloy with CNC machines.

Tyres
The McLaren F1 uses 235/45ZR17 front tyres and 315/45ZR17 rear tyres. These are specially designed and developed solely for the McLaren F1 by Goodyear and Michelin. The tyres are mounted on 17x9 inches and 17x11.5 inches cast magnesium wheels, protected by a tough protective paint. The five-spoke wheels are secured with magnesium retention pins.
The turning circle from curb to curb is 13 m (42.7 ft), allowing the driver two turns from lock to lock.

Brakes
The McLaren F1 features unassisted, vented and crossdrilled brake discs made by Brembo. Front size is 332 mm (13.1 in) and at the rear 305 mm (12.0 in). The calipers are all four-pot, opposed piston types, and are made of aluminium. The rear brake calipers do not feature any handbrake functionality, however there is a mechanically actuated, fist-type caliper which is computer controlled and thus serves as a handbrake.

Gearbox and miscellaneous
The standard McLaren F1 has a transverse 6-speed manual gearbox with an AP carbon triple-plate clutch contained in an aluminium housing. The second generation GTR edition has a magnesium housing. Both the standard edition and the 'McLaren F1 LM' have the following gear ratios: 3.23:1, 2.19:1, 1.71:1, 1.39:1, 1.16:1, 0.93:1, with a final drive of 2.37:1, the final gear is offset from the side of the clutch. The gearbox is proprietary and was developed by Weismann. The Torsen LSD (Limited Slip Differential) has a 40% lock.

The McLaren F1 has an aluminium flywheel that has only the dimensions and mass absolutely needed to allow the torque from the engine to be transmitted. This is done in order to decrease rotational inertia and increase responsiveness of the system, resulting in faster gear changes and better throttle feedback. This is possible due to the McLaren F1 engine lacking secondary vibrational couples and featuring a torsional vibration damper by BMW.

Interior and equipment
Standard equipment on the stock McLaren F1 includes full cabin air conditioning, a rarity on most sports cars and a system design which Murray again credited to the Honda NSX, a car he had owned and driven himself for 7 years without, according to the official McLaren F1 website, ever needing to change the AC automatic setting. Further comfort features included SeKurit electric defrost/demist windscreen and side glass, electric window lifts, remote central locking, Kenwood 10-disc CD stereo system, cabin access release for opening panels, cabin storage department, four lamp high performance headlight system, rear fog and reversing lights, courtesy lights in all compartments, map reading lights and a gold-plated Facom titanium tool kit and first aid kit (both stored in the car). In addition tailored, proprietary luggage bags specially designed to fit the vehicle's carpeted storage compartments, including a tailored golf bag, were standard equipment. Airbags are not present in the car.

The McLaren F1 were according to Gordon Murray obsessed over, which included the interior. The metal plates fitted to improve aesthetics of the cockpit are claimed to be 20/1000s of an inch thick to save weight. The driver's seat of the McLaren F1 is custom fitted to the specifications desired by the customer for optimal fit and comfort; the seats are hand made from CFRP and covered in light Connolly leather. By design the F1 steering column can not be adjusted, however prior to production each customer specifies the exact preferred position of the steering wheel and thus the steering column is tailored by default to those owner settings; the same holds true for the pedals, which are not adjustable after the car has left the factory, but like the steering column the pedals are also tailored to each specific customer.

During its pre-production stage, McLaren commissioned Kenwood to create a lightweight car audio system for the car; Kenwood, between 1992 and 1998 used the McLaren F1 to promote its products in print advertisements, calendars and brochure covers. Each car audio system was especially designed to tailor to an individual's listening taste, however radio was omitted because Murray never listened to the radio.

Every standard McLaren F1 also has a modem which allows customer care to remotely fetch information from the ECU of the car in order to help aid in the event of a failure of the vehicle.

Purchase and maintenance
Only 106 cars were manufactured, 64 of which were the standard street version (F1), 5 were LMs (tuned versions), 3 were longtail roadcars (GT), 5 prototypes (XP), 28 racecars (GTR), and 1 LM prototype (XP LM). Production began in 1992 and ended in 1998. At the time of production one machine took around 3.5 months to make.

Up until 1998, when McLaren produced and sold the standard McLaren F1 models, they had a price tag of around 970 000 USD. The cars can sell for up to nearly twice that of the original price, due to the performance and exclusivity of the machine. They are expected to further increase in value over time.

Though production stopped in 1998, McLaren still maintains an extensive support and service network for the McLaren F1. There are eight authorized service centers throughout the world, and McLaren will on occasion fly a specialized technician to the owner of the car or the service center. All of the technicians have undergone dedicated training in service of the McLaren F1. In cases where major structural damage has occurred, the car can be returned to McLaren directly for repair.

On October 29 2008, an McLaren F1 road car (chassis number 065) was sold at an RM Automobiles of London auction for £2,530,000 (~US$4,100,000). This was the car from the McLaren showroom on Park Lane, London. With only 484 kilometers on its odometer, this pristine example set a world record for the highest price ever paid for an McLaren F1 road car.

Koenigsegg Agera R, 2012

 

 

 

 Koenigsegg Agera R, 2012

At the 2011 Geneva Motor Show Koenigsegg is presenting the brand new Koenigsegg Agera R - Quicker than lightning! The Agera R on the Koenigsegg show stand - production car # 83 - is inspired by the legendary Speed Racer theme, as specified by the owner of the car. Speed Racers main colour is white - so is snow. Equipped with special Michelin tires and a custom made Thule Roof Box - Speed Racer is ready to attack the ski resorts!

In 2010 Koenigsegg presented a pre-production version of the Koenigsegg Agera. Since then the pre-production car and several test mules have continued the Agera development program. The Agera pre-production car has been driven by several influential motoring journals, resulting in raving reviews and awards, such as for example becoming the "Top Gear Hypercar of the Year". Please see attached quotes from these test-drives.

All in all the production versions of the Agera are created to take the Koenigsegg experience to the next level both on the road and the track, still maintaining the largest luggage space in the industry in combination with the unique Koenigsegg door system and detachable/stow-able hardtop.

There are several differences between the pre-production car previously shown and the production versions. For example, the engine and gearbox configurations are different and some revolutionary interior, chassis and aerodynamic features adorn the production version of the Agera that has never been shown before. For more information, please read the full press release below.

THE DESIGN
The Agera is designed with the minimalistic "less is more" philosophy in mind. This philosophy means that the shape of the car has to be purely functional with no added features except those purely needed to meet regulation, added safety, ergonomics, practicality and aerodynamics. We believe that if this philosophy is followed, the car will also be beautiful as it is purely purposeful. A good analogy is the evolution of a dolphin that has had to meet similar criteria in order to reach their present configuration through the evolution of nature.

The Agera is proportionate, compact and muscular. Its timeless, efficient and distinctive shape is truly a testament to time. The original shape and concept of the Koenigsegg CC, created 15 years ago, is still valid, fresh and highly competitive today. The Agera manage to stay true to the original philosophy, shape and size of the original CC. At the same time, it looks, feels and performs like something belonging to the future.

THE ENGINE
Koenigsegg differs from other low volume hypercar manufacturers by the fact that Koenigsegg develops and produces its own engine in-house. This is, by most observers and competitors, deemed as more or less impossible or way too expensive to even consider.

However, year after year Koenigsegg has proved them wrong. Not only are the engines developed in-house, they also have class leading characteristics in many important areas. To mention a few: Lightest and most compact hypercar engine in the world, weighing only 197 kg complete with flywheel, clutch, dry sump system, Inconel exhaust manifold with turbo. The low engine weight is quite astonishing, as the Agera engine also has class leading power and torque characteristics. To give an example, the Koenigsegg 5 litre V8 bi-turbo engine develops more than 900 hp on 95 octane regular fuel, and more than 1100 hp on E85 bio fuel. The Agera produces over 1000 Nm of torque from 2500 rpm and in the Koenigsegg Agera R format the engine has a peak torque of 1200 Nm over a 3300 rpm rev range, showing great flexibility.

These are extraordinary numbers considering the size and reliability of the engine without forsaking drivability or flexibility. This is truly downsizing, without drawbacks. These characteristics make it one of the most flexible and easy to use hypercar engines in the world.

To give a hint of how different the Agera engines are compared to other production car engines, it is easy to look at the BMEP value (Brake Mean Effective Pressure) in the cylinders during maximum power output. The best production diesel and petrol engines from other leading manufacturers have a maximum BMEP of around 22 bar.

The Agera engine has a BMEP of 28 bar running on 95 octane fuel and the E85 Bio fuel Koenigsegg Agera R engines has an astonishing BMEP of 30 bar. These numbers show how extreme the Koenigsegg engines are compared to any other production engine in the world. The reason why Koenigsegg can obtain such BMEP figures is due to some proprietary and critical factors:

•     A unique shape of the combustion chambers, improving the resistance against detonation.
•     High cylinder head clamp load, enabled by a specially designed engine block. This has proven to give a zero failure rate to combustion overpressure, even considering the extreme cylinder pressures.
•     A unique engine block design, where the cylinder sleeves are used to further stiffen the aluminium block.
•     A connecting rod design reducing TDC dwell time and therefore enabling higher mean pressures without detonation.
•     Exhaust manifold and intake plenum trumpets designed to ensure absence of RPM peak resonance and back pressure.
•     An efficient ejector pump system reducing the crankcase pressure and aerodynamic losses.
• The Koenigsegg engines also meet all the required emission standards in the world. This is nothing short of astounding, given their size and power output.

Koenigsegg has its own engine lab, with simulation programs, rapid prototyping machines, engine and chassis dynamometers, and a 1.7 km test track adjacent the factory enabling Koenigsegg to take the cars to 0-320-0 km/h at any time. Furthermore, a 25 minute drive away from the Koenigsegg Factory there is Knutstorp Racetrack, which is described by many as a miniature Nordschleife. Here Koenigsegg can put the engine and car through serious testing and make sure they work in perfect harmony. This gives Koenigsegg unique possibilities to develop technologies normally exclusive to much larger companies.

No other production engine in the world, regardless of car type, has the same amount of power potential compared to its EU cycle average CO2 emission(310g of CO2) or cycle fuel consumption( 14,7 litre per 100 km / 16MPG). However, what makes Koenigsegg most proud is how drivable, smooth, responsive, torquey and reliable the engines are - especially given their extreme performance.

Fuel consumption, and thus CO2 emissions, has been lowered. This is an astonishing feat for a 900+ hp hypercar. Turbo response is of vital importance when it comes to driving pleasure and the possibility to control massive amounts of power. Therefore Koenigsegg has joined forces with Borg Warner and adapted to the latest technology when it comes to turbine materials. The Koenigsegg Agera R turbines are made from a material called Gamma-Ti which is an inter metallic compound comprised of aluminium and titanium. This new material drastically reduces the inertia of the turbine wheel and axle and therefore gives improved response. Furthermore Koenigsegg has coupled this latest generation turbo technology with patent pending and proprietary response/back pressure reduction system, invented by Christian von Koenigsegg to really give the Agera engine a competitive edge when combining maximum power while complying with the strictest emission regulations in the world.

Furthermore the large air to air intercooler on the left side of the engine sucks enormous amounts of fresh air, eliminating the need for water in the intercooling system, thereby saving weight and avoiding heat soak issues, during extended performance driving.
Following the Koenigsegg tradition the engine has a dry sump lubrication in order to lower the engine as far as possible in the chassis and have full control of the crankcase oil even given the massive g-forces involved.

The large 80-litre tank ensures long driving range, due to the relatively low average consumption. The Agera follows the previous generation Koenigsegg and has its fuel tank well protected, built-in centrally into the carbon fibre monocoque chassis. Since the fuel is centrally placed in the car, the weight distribution does not change regardless if the tank is full or empty. Thanks to the safe fuel tank position, the challenging US high-speed rear impact test, was passed at first trial.
The Koenigsegg Agera R has four intelligent bio fuel grade return-less fuel pumps to deliver the correct amount of fuel at any given time. This reduces the energy needed to operate the fuel pumps and eliminates the waste of excessive fuel transport.

The inconel/titanium patent pending exhaust system is key in order for the Agera to achieve its remarkable emission and power levels. The exhaust system uses a completely new principle created by Christian von Koenigsegg. The new technology drastically reduces back pressure and gives earlier catalytic light off than any other turbo exhaust system. At the same time the acoustics of the exhaust has been examined carefully in order to maintain the typical Koenigsegg thunderous growl.

THE TRANSMISSION
The newly developed 7 speed gearbox for the Agera features a world's first dual clutch system for a single input shaft gearbox. In order to keep the gearbox light, compact strong and reliable, Koenigsegg together with Cima chose to develop a new gearbox type that enables the use of a combination of a dry and wet clutch system, in order to get class leading shift times. First there is the normal twin disc dry clutch that operates in a traditional fashion. Then there is a hydraulically operated wet clutch-brake inside the gearbox that is engaged during each up shift in order to slow down the input shaft, simultaneously as the gears are changed and prior to the normal synchronisation. This cuts the synchronisation time by two thirds, as the gear is presynchronized. The result is a very sporty, smooth and extremely fast shift. Compared to a traditional DCT system, this gearbox is lighter, smaller, has less moving parts and gives a more distinct shift feel, with almost no interruption to the acceleration. Furthermore, the electro hydraulic shift mechanism actuates the shift forks directly with no intermediate mechanical parts. This brings down the inertia of the shift mechanism and any potential slack is minimized since the shortest possible path of engagement is achieved.

Koenigsegg E-Diff
The Koenigsegg Electronic Differential (E-Diff) is lighter and faster, compared to traditional E-Diff solutions. The difference lies in the fact that Koenigsegg has retained a limited slip differential with plates and ramps with a built-in amount of analogue limited slip functionality. This means that the active hydraulic element can be smaller, more compact and therefore faster and lighter compared to traditional E-Diff solutions. The analogue part of the functionality also has zero processing time as it reacts directly. The analogue system is supplemented by a digital active system.

The way Koenigsegg has obtained one of the lightest and fastest E-Diff solution on the market. Furthermore the Koenigsegg developed algorithms that control the E-Diff, takes input from; throttle angle, g-force, steering wheel angle, yaw angle, car speed, engine rpm, selected gear, plus weather condition.
The way all this data is analysed and how the car reacts to this data also makes the Koenigsegg E-Diff unique and that makes the Agera very safe on the limit and improves performance and feel.
The Koenigsegg E-diff works in harmony with the new traction control system that is the fastest reacting in the industry, with auto adapt functionality to different road conditions and driving styles as well as several manual settings.

THE CHASSIS
The Agera´s unique carbon fibre monocoque chassis is designed to achieve its maximum stiffness without a roof, as the roof is detachable and stow-able in the front of the car. This in itself is an unusual feature for such a compact Hypercar.
The Koenigsegg carbon monocoque chassis has an astonishing stiffness of 65.000 Nm/deg and only weighs 70 kg including the integrated fuel tanks.
The result of constant weight saving exercises is a dry weight of only 1330 kg making the Agera the lightest fully homologated Hypercar presently in production.

THE SUSPENSION
The suspension geometry of the Agera was designed to further enhance the award winning behaviour of the CCX. The Agera track is wider at the front compared to the rear of the car, compensating for the narrower front tires and giving the car a square stance of 2 meters in both the front and the rear.

In typical Koenigsegg tradition, the Agera has the longest wishbones of all hypercars presently in production. Long wishbones have several advantages - for example: less track width deviation during wheel movement or cornering and improved geometry over a longer wheel stroke. This is one of the reason why F1 cars have very long wishbones. The wishbones are produced from seamless aeronautical chrome-molybdenum tubing, in order to minimise weight in combination with maximum strength and stiffness.

The extremely strong and light uprights are machined from 7075-T6 aeronautical grade aluminium, and contains 240 mm SKF dual angle contact bearings, normally only found on Lemans prototype cars. The very large bearings contribute to the overall stiffness of the wheel assembly and therefore give better control, handling and comfort. The uprights have large 4.5" diameter carbon fibre cooling ducts for the brake discs in order to maximise brake cooling.

Brakes
The Agera is equipped with the absolutely latest ABS technology and is based upon, a very lightweight and performance oriented, racing ABS system. The system makes it possible for the ABS function to react to differently depending on performance mode. Furthermore the ABS braking system operates on massive 392×36 mm and 380×34 mm ventilated and drilled ceramic discs, for unparalleled braking performance and zero fade regardless of track or road condition.

RTD (Rear Triplex Damper) Suspension
Christian von Koenigsegg has invented and pioneered a new type of rear suspension system for a road car. The Agera has a shock absorber and spring connecting the right and left rear wheel. This system gives unique benefits as the two rear wheels can influence one another when desired.
There are multiple benefits of this system. For example, the extra spring and damper works in series with the normal spring and dampers allowing their spring and damping rates to be lowered. This results in increased comfort and better handling on rough and wet surfaces without compromising dry track handling.

DEDICATED MICHELIN TIRES
Koenigsegg continued its long standing partnership with Michelin in the tire development for the Agera. Hence the Agera features specially developed, latest generation Michelin Super sport tires.
Due to the tires, advanced suspension and aerodynamics, the Agera achieves lateral accelerations up to 1.6 g in dry conditions with improved handling in wet.
The new tires were developed for the Agera through testing at the Michelin Ladoux test centre in France.
The tires fitted to the Agera are rated for speeds over 420 km/h making it the highest top speed rated tire in the world, whilst offering cup tire levels of grip and outstanding wet performance , all in one package.

VGR - Vortex Generating Rim spokes
The Koenigsegg VGR wheels are not only for looks. They are real air turbines, increasing the down force of the car by measurable amounts and improve brake cooling. All four wheels are individual so that turbine blades always face the correct direction for extraction. Given that the offset and width is different front to rear, all four wheels have their unique design. The VGR wheels are forged and then fully machined to the final shape. Due to the forging and machining process all excess material has been removed minimising weight, whilst displaying outstanding levels of stiffness.

THE AERODYNAMICS
The Aerodynamics of the Agera has been honed and perfected over many years in CFD and wind tunnel in order ensure best possible outcome. Even with the massive dynamic rear wing, the drag of the Agera is only Cd 0.33, in high speed mode and Cd 0.37 in track mode. Even though the Agera is a full 2 meters wide, it only has a frontal area of 1.87 m2. This results in a Cd*A value of only 0.62 and thus a theoretical top speed of around 440 km/h (Agera R), given the gear ratio and power available. All Agera models are limited to 375 km/h in standard mode, but can be unlocked by Koenigsegg for shorter periods of time, if all necessary conditions are met, such as road condition, tire wear, service level of car etc. The car is set in full speed mode by unlocking the top speed mode in the Infotainment system.

The two large side air intakes greatly add to the Agera´s high speed stability as they ensure that the pressure point of the car is behind the mass centre of the car. This makes the car more directionally stable with increasing speed. This is a crucial safety feature when it comes to driving at extreme speeds. Great care has been taken that the car also is stable under high speed braking. The front splitter and rear diffuser has been designed and optimized with this in mind.

Dynamic rear wing
Hypercars of today generate massive amounts of down force in low to medium speed and less down force in very high speed, in order not to overload the tires and not to create too much drag. Most hypercars therefore have heavy hydraulically operated wings and flaps to cater for this need.


Koenigsegg however, following the "less is more" philosophy, has designed a dynamic system to that take care of the above described needs. The most visual and obvious part of this system is the new dynamic rear wing. The wing changes its angle of attack, not with the help of hydraulics, but with the pressure of the wind. It is therefore dynamically controlled by the speed or wind resistance at any given moment in time and thus actually compensates for headwind or tailwind at the same given speed. This is an intelligent way of dealing with adaptive aerodynamics, as the system becomes lighter, less complex and more intuitive compared to heavy and complex hydraulics systems. Koenigsegg had to work heavily with CFD in order to create the dynamically controlled adaptive aerodynamics of the Agera.

An interesting multifunction feature of the adaptive wing is that the pylons for the wing also act as air extrusion channels. The air channels goes from the engine bay to the back of the pylons, thereby creating an air passage. This causes a venturi effect, from the air rushing past the pylon, evacuating hot engine bay gases, reducing pressure in the engine bay and increasing the flow of cooling air through the side radiators. This also means that the pressure under the car is reduced and giving more low drag down force.

THE INTERIOR
The interior of the Agera is like no other car. No other materials than those deemed worthy by Koenigsegg are allowed in the interior. This means that what you get to touch and see inside the Agera is only aluminium, carbon fibre, precious metals, alcantara and aniline leather. All switch gear is highly bespoke and features wonderfully unique solutions, as for example the Koenigsegg Ghost light, that make solid aluminium buttons gleam with LED powered symbols appearing out of nowhere. A world first in the car industry. The illumination shines through the billet aluminium buttons and surfaces by way of almost invisible micro holes, creating excellent visibility of the symbols as well as a very clean and stylish appearance, framed by an all-new carbon fibre centre console and tunnel assembly.

The new super light full carbon airbag steering wheel incorporates many vital functions directly in front of the driver. Similarly to the CCX, the shifting paddles are mounted directly on the steering wheel to enable shifting without taking your hands off the steering wheel during hard cornering.

The central high-definition touch screen infotainment system controls the audio functions, satellite navigation, Bluetooth phone and secondary functions such as performance meters and car telemetrical data.
The very comfortable and optionally heated carbon seats are great for long journeys but also give excellent lateral support when needed.

The Interior of the Agera is truly minimalistic and efficient in the purest Swedish sense. Nothing in the interior is there only to add visual drama; instead everything is there for a functional purpose. According to Koenigsegg, this is the essence of beauty, as it follows a less is more philosophy that embodies every engineering aspect of the Agera.

CI - Configurable Instruments
The CI is specifically developed for the Agera by Koenigsegg. It features a unique and configurable interface that can be adapted to driver specific demands. As it is connected to the cars CAN bus system it freely communicates with the infotainment screen and all other functions in the car.
By pushing the left stalk button, different priority graphics can be chosen, depending on need. For example in track driving mode, there is a focus on; RPM, pressures, temperatures, lap times, and g-forces. Compared to GT mode, where: car speed, auto shift, satnav, power, music etc is prioritized.

THE LUGGAGE SPACE
The luggage space is something Koenigsegg is very proud of. It is the largest luggage compartment in the hypercar world, with a space of over 120 litres. It is so well shaped that it actually can fit the one piece Agera roof/hardtop, meaning the driver can choose to go open or closed at any given time during a longer trip. Given the fact that Koenigsegg has engineered the roof to fit the car, it is actually also possible fit a set of golf clubs. This is unheard of in the hypercar world. Given the high comfort level and the large luggage space, the Agera can truly been seen as one of the first GT hypercars.

Custom Carbon fibre Thule Lightning Roof Box
At the 2011 Geneva Motor show, Koenigsegg presents the Koenigsegg winter package - the first lifestyle packages offered from Koenigsegg. The main element of this package is the exceptional Lightning Roof Box System.
The Lightning Roof Box is developed together with the Swedish rack and roof box manufacturer Thule. The high performance lightweight box is made completely from carbon fibre and has been through several iterations of CFD simulation to ensure it is safe up to 300 km/h, making it the fastest roof box in the world.

The roof box, which has an incorporated roof panel, replaces the normal roof in under 10 minutes. The standard roof is then stored in the luggage compartment in the front of the car, so that when the driver arrives to his destination, the roof box can be quickly removed and the normal roof can be put in place for a more elegant look.
The Lightning roof box truly enables the driver to use the Agera for longer trips with massive luggage. This gives a whole new spectrum of hypercar utilization.

THE ELECTRONICS
Not only does Koenigsegg develop their own engines, but also many of the electronic control units, CAN protocols, and management strategies are developed in-house. If you would look closely at many of the circuit boards in the car, inside the control units, you will find the name Koenigsegg in scripted directly on the circuit boards.

Lamborghini Reventon, 2008

 

 

 

 Lamborghini Reventon, 2008

Lamborghini prides itself on being the extraordinary manufacturer of extreme super sports cars without compromise. Sensuality and provocation characterise every Lamborghini, with an aggressively innovative style.

Born in Sant'Agata Bolognese
The Lamborghini Reventón has been entirely designed in Sant'Agata Bolognese, the original birthplace of the Lamborghini and the native home of every super car born under the sign of the bull. The design drawn up in Lamborghini's Centro Stile (Style Centre) is fine-tuned in close collaboration with the Lamborghini Research and Development Department. Thus, the Reventón is not only "haute couture" but it also stands out for its elevated dynamism whilst being entirely suitable for every day use.


The Lamborghini Reventón is not destined to remain a one-off. A total of 20 Lamborghini friends and collectors will be able to own this extraordinary car and, naturally, enjoy the incomparable pleasure of driving it.
The name Reventón has been chosen according to Lamborghini tradition. Reventón was a fighting bull, owned by the Don Rodriguez family. It is included in the list of the most famous bulls ever and is known for killing the famed bullfighter Felix Guzman in 1943.

The inspired by the fastest airplanes
The present day Lamborghini models are distinguished by the clear language of their shape. The coherent proportions of the Murciélago and Gallardo highlight their power and dynamism. Sharp edges, precise lines and clean surfaces: these are ingredients of a style reduced to the essential. Each element is created exactly according to its function; ornaments and decorations are totally foreign to a Lamborghini.
With the Reventón the Centro Stile designers have coherently developed this philosophy, inspired by another sphere where speed and dynamism reign absolute: modern aeronautics, responsible for the fastest and most agile airplanes in the world. This has created an extremely precise, technically striking style with a new vitality: interrupted lines and contorted surfaces create a fascinating play of light, giving the car incredible movement.

Made of carbon fibre and precision
Though it is based on the extraordinarily successful Murciélago LP640, the exterior design of the Reventón is completely new. Just like the base model, the exterior is made of CFC, a composite carbon fibre material, which is as stable as it is light. The exterior components are glued and fixed to the body comprised of CFC and steel.
The front is characterised by the acute angle of the central 'arrow' and by the powerful forward-facing air intakes. Though they do not supply air directly to the turbine like an airplane, bearing in mind the 650 hp, an abundant volume of air is necessary to cool the carbon brake disks and the six cylinder callipers.

The characterised by coherent functions
Both doors on the Reventón open upwards - since the legendary Countach this has also been a symbol of the V12 Lamborghini product line. With their asymmetric configuration, the large air intakes below the doors provide an example of the extreme coherence with which a Lamborghini fulfils its function: on the driver's side it is large to increase the flow of oil to the radiator. On the passenger's side of the vehicle, the air intake is flat because in this case, it only has to ensure the flow below the floor. The aerodynamically optimised flat floor structure terminates at the rear with a diffuser featuring an accentuated shape. This guarantees excellent road grip and stability even at 340 km per hour.

In spite of the extreme and innovative language of its shape, the Reventón not only maintains all the strong features of the Murciélago LP640, but also offers further amelioration in terms of aerodynamics, the important engine cooling system, the air intake system and brakes. The airflow and the section of the variable geometry air intakes of the engine and the rear spoiler (also adjustable) have been modified.

Perfected to the ultimate detail
The engine hood made of glass laminate with open ventilation slits offers a glimpse of the beating heart of the twelve cylinders of the super car. The glass also features the marked arrow angle that characterises the design from the front to the rear spoiler. The Lamborghini designers' love for detail is beautifully illustrated by the fuel tank lid: a small mechanical work of art, achieved by milling a solid aluminium block.

The combination lights transform the incisiveness of the design into light: the front features the most modern light-emitting diodes alongside Bi-Xenon headlights. Seven LEDs ensure continuous daylight while there are a further nine diodes for the indicator and hazard lights. Another technical innovation is found in the rear light LEDs. Because of the high temperature in the rear low part of the car, special heatproof LEDs are used for the indicator and hazard lights, stoplights and rear lights with a triple arrow optical effect.

TFT display similar to an airplane
The same innovative force applied to the exterior design characterises the cockpit of the Reventón. Designed and created using Alcantara, carbon, aluminium and leather that comply with the top quality standards, the interior is inspired by the next generation cockpits: just like in modern airplanes, the instruments comprise three TFT liquid crystal displays with innovative display modes. At the touch of a button, the driver can choose from two vehicle information display modes. The instruments are housed in a structure milled from a solid aluminium block, protected by a carbon fibre casing.

The G-Force-Meter is also completely new: this display shows the dynamic drive forces, longitudinal acceleration during acceleration and braking, as well as transversal acceleration around bends. These forces are represented by the movement of an indicator on a graduated 3D grid depending on the direction and intensity of the acceleration. A similar instrument can be found in the airplanes. Formula One teams also use a similar device to analyse dynamic forces.


Customisable instruments
The instrument on the left of the speedometer associates the number of revolutions in the form of a luminous column with the display of the selected gear. Finally, every Reventón is equipped with a robotised e.gear controlled by two small levers under the steering wheel.

By simply pressing a button, the driver can switch to the second, quasi-analogical display, where the classic circular instruments, speedometer and engine speed indicator are configured in an equally innovative way and transformed into luminous pilot lamps with varying colours. The G-Force-Meter naturally remains at the centre in this display mode.

The Electronic system developed entirely by Lamborghini
All this is possible thanks to the fact that the entire electronic platform of the Reventón, together with all the control devices, has been autonomously developed by the Lamborghini experts.

From the conception of the very first radical ideas, the entire Reventón has been developed in Sant'Agata Bolognese thanks to tight teams of remarkably creative experts. An extremely refined and efficient process was employed: CAD design and development, creation of the prototype in the Prototype Department, all carried out under the constant supervision of the Research and Development Department's technicians and testers.

Atelier of creativity and high efficiency
Inaugurated in 2004, the Centro Stile is dedicated to design and characterised by a high degree of efficiency: an "atelier" of creators, designers and prototype constructors, who encapsulate the Lamborghini culture and spirit by using their remarkable skills to create aesthetic innovation.

The Centro Stile is located in a 2,900 square two-storey building. The large pavilion houses two test floors and related production and analysis equipment, while other rooms are set aside for the most advanced computerised workstations for designers and a style-model construction workshop. The Centro Stile is also closely linked to the nearby Engineering Department: the direct line between the Lamborghini development departments guarantees that ideas rapidly become reality.

The Lamborghini Reventón is a practical illustration of the streamlined functionality and efficiency characterising the Centro Stile: it took less than a year to progress from the first ideas to the finished car. The complete design process from the first sketches on paper, to three dimensional computer models with 1:10 or 1:4 scale, right up to the real size prototype is organised around streamlined, fast, efficient work groups. Thanks to the Centro Stile, for the first time in its history, Lamborghini is now able to create its own style philosophy in-house without having to rely on any external collaboration.

Florida Car Accident Lawyers and Attorneys

Pursuing Florida Auto Accident Claims
If you are involved in a car crash in Florida and wish to file a claim against the person you believe responsible for the incident in a Florida court, you should make yourself aware of the basic laws the State of Florida employs in determining liability and awarding damages to plaintiffs.

Every individual operating a motor vehicle within Florida has a duty to exercise reasonable care in the operation of that motor vehicle. The burden of reasonable care makes drivers accountable for acts which they knew would likely result in personal or property injury and for acts which they should have known would likely result in personal or property injury. Florida state law identifies a driver's failure to use reasonable care as negligence. Negligence represents the first requirement for a successful lawsuit.

Once you have established the negligence of a party, you must show that their negligence caused the accident that resulted in your lawsuit. "Causation," in a legal sense, can be a complex issue, but suffice it to say that if the negligence of the party resulted in the injury to person or property for which you have sued, causation exists.

Finally, in order to maintain a suit as the result of an automobile accident, you must prove that you have suffered damages. Damages include economic injury, such as lost income or wages, medical and funeral expenses, lost support and services, and replacement value or repair costs of personal property damaged in the accident. In addition damages may include non-economic injuries such pain, suffering, mental anguish, and inconvenience as a result of bodily injury that result for the accident.

The State of Florida has a "No-Fault" law, which requires your auto insurer to pay for non-economic damages, regardless of who caused the accident. Florida enacted this law as a way to reduce auto-injury fraud, thereby keeping insurance costs down. Florida does have exceptions to the "No-Fault" law. You may collect non-economic damages from the at-fault party if you can establish that the bodily injury resulted in: 1) significant and permanent loss of important bodily function; 2) permanent injury; 3) significant and permanent scarring or disfigurement; or 3) death.

A court may reduce your damages, if the defendant can establish that actions on your part contributed to the accident. This principle, known as "comparative negligence," holds that a court can reduce your damage award by the percentage for which a jury found you responsible for the accident. For example, if you establish damages in the amount of $10,000, but the jury finds that your negligence constituted twenty percent of the reason the accident occurred, then your damage award would be reduced by twenty percent, to $8,000.

Florida law also allows the reduction of damage awards by any amounts you might have received from public or private insurance to compensate you for your losses. Under this rule, known as the "Collateral Source Rule," if you received $1,000 from your auto insurer to cover your medical expenses after an accident, a court may reduce your damage award, if it includes medical expenses, by $1,000.

Top TenSuper Expensive Cars In The World

Super Expensive Cars In The World:
Top 10 List 2011-2012

World's Super Expensive Cars

The most expensive car in the world?

The 1931 Bugatti Royale Kellner Coupe was sold for $8,700,000 in 1987. However, that car and many alike will not be included in this list because it is not available on the market today. It is hard to imagine someone would actually spend 8 million dollars on a car instead of using it for something more productive. When you had the money and opportunity, you would probably spend a small fraction of it on a collection of supercars for your private garage.

The 10 super expensive production cars on the market.

1. Bugatti Veyron Super Sports $2,400,000. This is by far the most expensive street legal car available on the market today (the base Veyron costs $1,700,000). It is the fastest accelerating car reaching 0-60 in 2.5 seconds. It is also the fastest street legal car when tested again on July 10, 2010 with the 2010 Super Sport Version reaching a top speed of 267 mph. When competing against the Bugatti Veyron, you better be prepared!

2. Pagani Zonda Clinque Roadster $1,850,000. One of the most exotic cars out there is one of the most expensive. It can go from 0-60 in 3.4 seconds with a top speed of 217 mph.

3. Lamborghini Reventon $1,600,000. The most powerful and the most expensive Lamborghini ever built is the third on the list. It takes 3.3 seconds to reach 60 mph and it has a top speed of 211 mph. Its rarity (limited to 20) and slick design are the reasons why it is so expensive and costly to own.

3. Koenigsegg Agera R $1,600,000. The Agera R can burn 0-60 in 2.8 seconds, reaching a maximum speed of 260 mph. It has the parts to reach 270 mph, but the supercar is electronically capped at 235 mph. With the completion of certain paperwork, the company will unlock the speed limit for one occasion.

4. McLaren F1 $970,000. In 1994, the McLaren F1 was the fastest and most expensive car. Even though it was built 15 years ago, it has an unbelievable  top speed of 240 mph and reaching 60 mph in 3.2 seconds. Even today, the McLaren F1 is still top on the list and outperforms many other supercars.

5. Ferrari Enzo $670,000. The most popular supercar ever built. The Enzo has a top speed of 217 mph and reaching 60 mph in 3.4 seconds. Only 400 units were produced and it is currently being sold for over $1,000,000 at auctions.

6.Pagani Zonda C12 F $667,321. Produced by a small independent company in Italy, the Pagani Zonda C12 F is the 6th most expensive car in the world. It promises to delivery a top speed of 215 mph+ and it can reach 0-60 in 3.5 seconds.

7.SSC Ultimate Aero $654,400. Don't let the price tag fool you, the 7th most expensive car is actually the 3rd fastest street legal car in the world with a top speed of 257 mph+ and reaching 0-60 in 2.7 seconds. This baby cost less than half as much as the Bugatti Veyron, yet has enough power to compete against the most expensive car. It is estimated that only 25 of this exact model will ever be produced.

8.Ascari A10 $650,000. This badboy can reach a tested top speed of 215 mph, zooming 0-60 in 2.8 seconds. The British car company plans to assemple 50 of these supercars in their factory in Banbury, England.

9.Saleen S7 Twin Turbo $555,000. The first true American production certified supercar, this cowboy is also rank 4th for the fastest car in the world. It has a top speed of 248 mph+ and it can reach 0-60 in 3.2 seconds. If you are a true American patriot, you can be proud to show off this car.

10.Koenigsegg CCX $545,568. Swedish made, the Koenigsegg is fighting hard to become the fastest car in the world. Currently, it is the 5th fastest car in the world with a top speed of 245 mph+, the car manufacture Koenigsegg has just released the Koenigsegg Agera R to compete against the Bugatti Veyron.
