•  Lamborghini Aventador J Concept, 2012

At the 2012 Geneva Motor Show, Automobili Lamborghini is presenting the most uncompromising open super sports car of its entire history. The Lamborghini Aventador J is a force of nature on wheels - supremely powerful and supremely open. The Aventador J offers its pilot and co-pilot an utterly indescribable experience of power and dynamics. At the same time, the 515 kW / 700 hp two-seater is a first class technology showcase, combining innovative solutions and brand new materials and demonstrating Automobili Lamborghini's enormous expertise in carbon fiber technology.

The Lamborghini Aventador J is a radically open automobile - exterior and interior meld into each other. The designers and engineers in Sant'Agata Bolognese have not only dispensed entirely with the roof, but also with the front windshield. This requires that drivers of the Aventador J must have the right equipment for driving at top speeds higher than 300 Km/h.

The kind of driving at the limit is a highly exclusive experience - the Lamborghini Aventador J is fully functional for road use. It is an absolute one-off: a one-of-a-kind piece of art.

Continuation of a glorious tradition
With the Lamborghini Aventador J, technically based on the Aventador, Automobili Lamborghini is carrying on its glorious brand tradition. The 1970 Jota, for instance, was the stuff of legends - a Lamborghini Miura with improved performance and virtually redesigned in every detail. It remained a one-off; although some owners subsequently had their Miuras modified to look like the Jota.

The letter J is derived from the sporting rules of the FIA world motorsport organization. Its "Appendix J" defines the technical specification of race cars in the various classes.

The Aventador: Extremely open, overwhelming power
The Lamborghini Aventador J is a super sports car of positively dramatic single-mindedness and openness. It combines the overwhelming performance of the Lamborghini Aventador with the most intense experience of power and dynamics imaginable in an automobile.

The technical basis for the Aventador J is the Aventador LP 700-4, Lamborghini's new twelve-cylinder model. Presented in 2011, the Aventador has been acclaimed by customers and journalists alike. The Lamborghini Aventador LP 700-4's technology package is unique - its structure is based on an innovative monocoque made from carbon fiber reinforced polymers that combines systematic lightweight design with optimum stiffness and safety. The new twelve-cylinder with a displacement of 6.5 liters and 515 kW / 700 hp combines the best in high-revving thrills with mighty pulling power. Its super-fast ISR transmission, permanent all-wheel drive and push-rod suspension combine this potent power with the utmost handling precision.

Systematic lightweight design - considerable weight reduction
Naturally, the Aventador J benefits enormously from this unique technology package. Yet the Aventador J has a significantly different interpretation to the Aventador coupé. In this open version, the monocoque has a largely new design, including the two safety bars behind the seats. The absence of a roof, of the large windshield, of the air conditioning system and of the navigation system obviously takes it to an even lower weight. With a dry weight of 1575 kilograms, the series production Aventador LP 700-4 is already extremely light for its performance class thanks to its carbon fiber construction.

Carbonskin, a brand new carbon fiber material
The unique expertise of Automobili Lamborghini in the field of carbon fiber reinforced polymers is evident not only in the hi-tech monocoque, but also in the research into further innovative solutions. Unlike traditional seats, in the Lamborghini Aventador J seats are made of Forged COMPOSITE®, with inserts of flexible carbon fiber fabrics: a result of an innovative Lamborghini patent.

The specialists at Lamborghini have developed an even more amazing version of carbon fiber material for the Aventador J. In its first automotive application, this carbon fiber fabric called "Carbonskin" is made of woven carbon fibers soaked with a very special epoxy resin that stabilizes the fiber structure and keeps the material soft. Like a hi-tech fabric, the carbon fiber mats fit perfectly to every shape. In the Aventador J, the complete cockpit and parts of the seats are clad in this material and shimmer in matt carbon fiber black. It's conceivable that in future there will be many potential applications for this freshly patented and extremely fine-looking material, even very high-end clothing.

The Design: uncompromisingly Lamborghini
An extreme Aventador obviously needs an equally single-minded design, which goes without saying at the Centro Stile Lamborghini. Every single model from Sant'Agata Bolognese bears the unique design of the brand. Clear, precise surfaces, as well as sharp, often broken lines are among the unmistakable styling tools. They consistently emphasize the power and enormous presence of these Italian super sports cars. Not one line is ever accidental - the defining principle is always 'form follows function'.

The function is very clearly defined for the Aventador J - explosive dynamics, extreme driving fun, a unique experience. Every kilometer with the Aventador J is extreme fun: something plainly evident from the very first glance.

Rear view mirror like a periscope
Virtually every part of the outer chassis was redesigned for the Aventador J, yet it shows the spirit of Lamborghini in its most concentrated form. The car's dimensions are extreme: the overall length is 4890 mm, the overall width (excluding mirrors) is 2030 mm while the height is 1110 mm.

The highest points are marked by the rear view mirror, which is perched on an arm like a periscope, and by the two safety bars behind the seats. In place of the classic front windshield there are two small wind deflectors. The occupants of the Aventador J are confronted by the element of the wind in much the same way as a superbike rider - therefore the right clothing is prerequisite for every trip.

Front scoop with winglets
The front of the Aventador J is somewhat narrower than that of the Aventador. The front end is dominated by a highly distinctive carbon fiber air scoop, with central fixing braces and upward tilting winglets on the outer edges. Viewed from the side, the front end of the Aventador J looks like a Formula 1 racing car.

Red with chrome effect, wheels with CFRP fan
The black of the carbon fiber parts is visibly evident throughout the car - the significantly wider sill elements and the mighty rear diffuser form a perfect contrast to the rich red body paintwork. The special red color was developed specifically for this Aventador - a highly intensive red with a slight chrome effect.

The wheels, of course, were also developed specifically for this car, with 20-inch rims at the front and 21-inch at the rear. The five-spoke aluminum wheels have a central lock system and an additional carbon fiber insert that functions like a small fan for optimum brake ventilation.

Naturally, the doors on the Lamborghini Aventador J also open upward. They are considerably thinner than on the Aventador and are fitted with a tiny, fixed side window. The muscular flanks around the rear wheels are hallmark Lamborghini and make it immediately apparent where this particular bull keeps his power.

Rear end purely for aerodynamics and ventilation
Because of its ample dimensions, the eye is drawn inexorably to the rear end. It consists in principle of just three elements - the carbon-fiber rear diffuser, the four huge tail pipes and the rear lights with their typical Lamborghini light signature in the form of a Y. The remaining surface area is for heat dissipation and is enclosed only by a black metal mesh. The rear end is crowned by an enormous fixed spoiler mounted on the bodyshell by two arms. 'Form follows function' to the nth degree. The spoiler is supported by two pillars connected by the diffuser: clearly inspired by racing.

Special bumpers
In comparison with the Aventador LP 700-4, the exclusive Aventador J has special front and rear bumpers. Both bumpers have been supplemented with carbon fiber fins that act as flow deviators. Their purpose is to achieve a significant increase in the vehicle's downforce at both the front and the rear.

The outside comes inside
The Aventador J's exterior and interior forms flow seamlessly into each other. This supersports car turns its inside outward and is as open as it can possibly be. Conversely, the exterior 'flows' through the interior - a red stripe runs from the front hood, between the two wind deflectors, over the dashboard, down the console to the center tunnel and back up between the seat backs, before leaving the interior and heading for the engine cover panel.

Interior is minimalist and single-minded
This band of color connects the front and the rear of the car, creates a visual separation between the driver and passenger space and is interrupted only by a small control panel housing the starter button and the switches for lights and transmission. The Lamborghini Aventador J is equipped neither with a navigation nor car audio system, nor does it have the associated screen or air conditioning controls - these would simply detract from its one and only raison d'être as an extreme driving experience. What remains, of course, are two programmable TFT displays behind the steering wheel.

The engine cover also brings the inside to the outside. To be more precise, it is not so much a cover but more a framework. This part has a new geometry (X shape) and is made of carbon fiber. Two large openings lay bare both cylinder banks of the mighty V12 power unit with its 6.5 liters of displacement - a truly stunning sight for every automobile aficionado.

A unique work of art licensed for the road
However, at the end of the Geneva Motor Show, this sight will be the preserve of just one - the future owner of the Lamborghini Aventador J. There is only one of them, no prototypes and no others for the Lamborghini Museum. The buyer can look forward to a truly unique, street-legal work of art. He will possess the most extreme expression of Lamborghini DNA in existence and a real masterpiece of high technology. But the many other fans of the super sports cars from Sant' Agata Bolognese can rest assured - the Aventador success story has only just begun.

KTM X-Bow, 2008

 

 

• KTM X-Bow, 2008

An aggressive design and sporty potential: the KTM X-Bow is not merely a milestone in the KTM brand's more than 50-year history, it's also a new citation in the small, but elite segment of radical, lightweight sports cars. This exceptional position is the result of the concept: for their first car, KTM employs the finest materials, high-tech and the know-how of respected development partners such as Audi and Dallara. The result is a street-homologated sports car with racing technology, like an avantgarde, carbon fibre monocoque. Thanks to the basic version's light weight and the 177 kW (240 hp) Audi TFSI engine, the performance values of the KTM X-Bow outstrip those of super-sport cars with more than twice the power: with a deadweight of approx. 700 kilos, the KTM X-Bow accelerates to 100 kph in just 3.9 seconds.

But the KTM X-Bow isn't just a racing machine, even if it is going to accomplish spectacular performance feats on racing circuits. With its modern technologies and exceptional solutions, it's much more oriented towards sporty drivers who seek a purist's driving experience. By foregoing electronic assistants and today's standard comfort features, the X-Bow offers an unfiltered adventure - aided by its standalone wheels in the style of monoposto racing cars, transparent technology and the car's reduced concept, i.e. no roof, doors or windscreen. The sports car has only a 70-millimeter, transparent wind deflector. With all these unique features, driving the KTM X-Bow becomes an experience with an immediacy that otherwise can only be felt when riding a motorcycle.

The Next Step into the Future
For the Upper Austrian motorcycle manufacturer - Europe's second largest - the decision to expand its line of business into the automobile market was of great strategic significance. It was made possible by the company's extraordinarily dynamic growth over the past 15 years. Since 1992, KTM vehicle sales have risen an average of 21% each year, while the volume of sales even climbed to 25% each year. Today, KTM is the world's leading brand in the offroad segment and in recent years has successively expanded its model portfolio into the street sector. "Moving into the automotive sector is the logical continuation of this strategy. With the X-Bow, KTM can now offer the classic KTM driving experience to all those who don't have a motorcycle licence," says Stefan Pierer, CEO of the listed KTM Power Sports AG, explaining this investment in the company's future.

Carbon Fibre Monocoque: Racing Know-How from Dallara
Carbon fibre monocoques have been the Formula 1's safety net for years. On the road, this technology was formerly reserved for the elitist, supersports cars in the highest price classes. KTM would now like to be the first to offer this solution in a much more affordable environment.

KTM has thereby been able to call upon the expertise of its development partner, Dallara. These specialists from Varano (near Parma) in Northern Italy have long been acclaimed as carbon technology experts, from the conception to the production of components made of this light, yet rigid material. The monocoque developed for the KTM X-Bow is not only extremely robust it is also safe, thanks to an integrated crashbox. And yet it weighs only about 70 kilos and is therefore a crucial factor in the vehicle's spectacular performance.

The Engine: TFSI Technology from Audi
KTM was able to gain Audi AG as its partner in developing the drive unit. The four-cylinder TFSI engine represents the X-Bow's construction principles in an ingenious way: by featuring lightweight, high-performance and intelligent technologies.

The engine's outstanding attribute is its gasoline direct injection technology, FSI. In this case, it's combined with an exhaust turbocharger plus an intercooler. Thanks to FSI, the engine can utilize fuel better than one with ordinary intake manifold injection and it even gets by on less fuel in the frequently used partial load range.

The injection takes place at a pressure level between 30 and 110 bar, valves in the intake system direct the inflowing air into a cylindrical movement. A continuously variable intake camshaft ensures optimal cylinder charging at any speed. Two balancer shafts compensate the second order inertia forces and so guarantee superior, low-vibration operation.

The KTM X-Bow's long-stroking, four-valve engine delivers a powerful performance: 310 newton-metres of torque peaks at a level between 2200 and 4000 rpm. The peak performance of 177 kW (240 hp) is achieved at 6000 rpm. Even more powerful engine variations in the 300-horsepower range are planned at a later date.

The drive unit package is complemented by a manual 6-gear transmission, which is also made by VW and can be equipped with a limited-slip differential if so desired. An optional S tronic transmission will also be offered. The drive comes from the rear wheels.

The Chassis: Direct and Competent
The X-Bow's driving dynamics profit not only from the car's low centre of gravity but also from its superior chassis, which also draws on racing technology for its basic principles. Suspended on double triangular wishbone axles, the wheels feature suspension and damping elements by WP Suspension, with a pushrod arrangement up front.

The Italian brake manufacturer Brembo can also be proud of its reputation for excellence. KTM is also expanding this partnership (which began in the motorcycle sector) into the automobile realm. The X-Bow's powerful braking system consists of 305 mm discs at the front and 262 mm discs at the rear. The interaction of the vehicle's light weight, ideal balance, low centre of gravity and a 17-/18-inch tyre mix results in spectacular braking performance: when the brakes are warm, the KTM X-Bow needs only 33.1 metres to decelerate from 100 kph to a standstill.

The Aerodynamics: Exceptional Contact Pressure
The primary development goal for the KTM X-Bow was not attaining extreme final velocities, but in optimising the driving dynamics. The sports car is thereby aided by an ingenious aerodynamics arrangement, the result of many hours in Dallara's wind tunnel. The most vital element in this area is the underbody, which is equipped with a prominent diffusor at the rear. To make this diffusor work even more effectively, the linking points for the rear suspension were set as high as possible. This enables the KTM X-Bow to achieve a phenomenal downforce of about 200 kilograms at a speed of 200 km/h - about three times more than most other supersport cars.

In combination with the high-performance chassis, this fantastic downforce makes extreme curve speeds possible. The transversal acceleration of 1.23 g that can thus be attained noticeably surpasses the usual values achieved by street homologated sports cars.

The aerodynamic concept was a great challenge for the designer as well. It meant that sufficient air had to be channelled into the inlets located in the sides, behind the passengers. The radiator is also located at the rear of the vehicle, to avoid having to install longer, heavier cooling hoses. This mission was accomplished by using special air baffles, which are installed horizontally on the sides of the car so the passengers can also use them as boarding aids.

Safety: Racing Technology
The crucial component protecting the driver and the passenger is the solid, carbon fibre monocoque - safety technology straight from Formula 1. This structure is supplemented by a crashbox in the nose of the vehicle. The silencer, which is built into the rear of the car, was also designed to act as a crashbox; it absorbs the force of an impact to the rear of the vehicle.

The driver and passenger are also protected by four-point safety belts, which were inspired by the racing world. If so desired, this unit can be equipped with a fifth securing point. The two roll bars are clearly visible. They not only appear to be solid, they are skilfully integrated into the monocoque's structure.

Design: Floating Elements
Gerald Kiska's design studio can take credit for the shape of the vehicle. Coming from Salzburg, he has worked closely with KTM for the past 15 years and is entrusted not only with the design of the motorcycles, but also with the appearance of the company itself.

For the concept of the KTM brand's first automobile, Kiska incorporated many characteristics that are more closely associated with motorcycles than cars. Every part fulfils a function, the technology remains transparent, the form is noticeably simple. The few, orange-coloured body panels are "floating elements", like those of motorcycles, and suggest lightness and simplicity.

The deliberate reduction in all things even includes the lights: simple headlamps, embedded indicators flush with the car's contours and round lights at the rear forego superficial, showy effects. Instead, the carbon structure also takes on design duties, meaning that components which are frequently hidden in cars, such as the silencer, suddenly serve an aesthetic purpose in addition to their usual functions.

The Equipment: Puristic and Functional
As a result of its clear concept, the KTM X-Bow can do without a lot of elements that ordinarily add complexity and extra weight. So the narrow wind deflector makes an elaborate heating system and windscreen wipers unnecessary; doors are also not included in the design, due to the vehicle's low profile and the extra-low side profile.

The seats are further examples of the X-Bow's intelligent and simple construction: the shells for the driver's and passenger's seats are already integrated into the carbon fibre construction of the monocoque. An overlay provides solid comfort. In order to provide the best ergonomics for drivers of various heights, the KTM X-Bow has manually adjustable pedals.

The KTM X-Bow doesn't have a luggage compartment. But it does feature an innovative, mobile storage box for the car documents. The equipment required by law, such as the warning triangle, first aid kit and a tyre-fit system, are kept in storage compartments beside the passenger's foot well. A cover is stowed in this same location; it protects the interior of the car when it's parked. Two helmets can be fixed in the passenger's legroom.
