McLaren MP4-12C GT3, 2011

McLaren GT, a new race car manufacturer which brings together the expertise of McLaren Racing, McLaren Automotive and CRS Racing, unveiled the McLaren MP4-12C GT3 race car and plans for a 2011 development programme.

The new McLaren MP4-12C GT3 will be the first McLaren car built for FIA GT series racing since the McLaren F1 GTR finished production in1997. The 12C GT3 is based on the new MP4-12C high-performance sports car and a team of engineers, designers and test drivers with vast experience in Formula 1 and GT racing has been assembled to undertake the process of adapting the carbon chassis-based 12C to racing specification.

Drivers and FIA approved races confirmed for 2011
McLaren GT aims to deliver the highest quality, most reliable and most driveable car on the GT3 grid when 20 cars are delivered to privateer teams for racing in Europe in 2012. The unique combination of McLaren and CRS Racing's technology and development methodology is matched by McLaren GT's appointment of experienced and successful racing drivers to develop the 12C GT3 at challenging races over the 2011 season.

McLaren GT plans to debut the new McLaren MP4-12C GT3 at this season's Blancpain Endurance Series race at Spain's Circuito de Navarra, followed by Magny-Cours in France and Silverstone in England. As part of the development programme for the 12C GT3, McLaren GT also expects to enter the Total 24 Hours of Spa endurance race.
CRS Racing Team Principal Andrew Kirkaldy will be joined by 2010 Vodafone McLaren Mercedes test driver Oliver Turvey and Portuguese racing driver Álvaro Parente in the McLaren GT driver line-up for the 2011 development programme.
McLaren fans eager to see McLaren's first GT racing car since the legendary McLaren F1 GTR can expect to see the new 12C GT3 driven up the famous Hill at Goodwood Festival of Speed from 01-03 July 2011.

McLaren MP4-12C GT3 development targets

McLaren GT comprises a team of designers, engineers and test drivers with vast experience in developing successful race and road cars. Marcus Waite, McLaren GT Chief Engineer, began his career working with the McLaren Formula 1 Simulation Group. A move onto the Formula 1 team where he was Senior Test Team Engineer for many years was then followed by his appointment to McLaren Automotive as Test Team Leader responsible for the new MP4-12C sports car. Combining practical experience of Formula 1 car development methodology and a deep understanding of the 12C road car's technical specification is invaluable to McLaren GT.

The McLaren MP4-12C: The essence of a race car
Racing experience and development tools have played a key part in readying the 12C GT3 for its 2011 race programme. But, before the racing car takes to the competitive grid, McLaren, in the form of McLaren Automotive set out to develop a high-performance sports car that set new standards for speed, handling, efficiency, braking and driveability: formed from an obsession for aerodynamic purity and lightweight engineering. Assets and goals that make the McLaren MP4-12C a perfect road car from which to develop a race-winning GT car.

Once plans were agreed to take the 12C racing, key members of McLaren Automotive's design and engineering teams were eager to support this natural step at McLaren.
Under the McLaren Orange skin, the 12C GT3 shares the same 75kg carbon 'MonoCell' chassis as the 12C road car. Since the modern McLaren was formed in 1981, the company has used only carbon fibre for the chassis construction of all its road and race cars: it was a natural choice for the heart of the MP4-12C. Lightweight construction and manufacturing innovation through Resin Transfer Moulding was a priority for the engineers and designers responsible for the 12C's chassis. The result is a road car that, at 1301kg, is the lightest in the 'core' sector of the high-performance sports car market.
Andrew Kirkaldy said: "I believe the MP4-12C is an engineering masterpiece and that starts with its carbon chassis. A rigid chassis is hugely important to a racing driver. The McLaren MonoCell is unequalled as a safety cell, and our engineers can be sure that any changes made to the chassis set-up will have the desired effect because of its structural rigidity and predictability.

CRS Racing to deliver on expectations of a new McLaren race car
The prevailing design concept of the new McLaren MP4-12C road car is 'designed around the driver', and this is just one example of McLaren's uncompromising commitment to offering a new driving experience in road and race cars. CRS Racing Team Principal Andrew Kirkaldy brings a decade of GT-level racing experience to McLaren GT and, as the team's project manager, Kirkaldy was able to specify the cockpit and other attributes of the 12C GT3 to ensure restrictions normally associated with GT3 race cars are removed from the McLaren.

Specification and performance reflect McLaren expectations
Just as with the 12C road car, McLaren is working closely with specialist suppliers to deliver an innovative and lightweight car. The 3.8-litre McLaren V8 twin turbo 'M838T' engine supplied in the road car also features in the 12C GT3, but de-tuned to 500 PS (from 600 PS) in order to provide optimum power for this performance-balanced race car.

The new McLaren MP4-12C GT3 will feature a unique engine calibration, bespoke racing transmission developed in partnership with Ricardo (who also developed the engine with McLaren) and a suspension arrangement tuned specifically for racing.
McLaren GT has selected the TAG-400 Engine Control Unit for the new 12C GT3. The TAG-400 is a compact, self-contained engine management system and data logger for race engines designed and built by McLaren Electronic Systems. The procurement of components from suppliers used to working with partners in Formula 1 is another example of McLaren GT delivering on its objective to build a GT3 car of unrivalled quality and reliability.

McLaren MP4-12C, 2011

 
 
McLaren MP4-12C, 2011

The McLaren MP4-12C is revealed as the first in a range of high-performance sports cars from McLaren Automotive, the independent car division based at the McLaren Technology Centre in Woking, England. The 12C, and future models within the range, will challenge the world's best sports cars, benefiting from the expertise and virtuosity of the McLaren Group.

20 years of sports car design, engineering and production combined with inspirational success in Formula 1 have driven Ron Dennis, McLaren Automotive Chairman, to announce his plans for the ultimate line-up of technology-led and customer-focused performance cars for the 21st century. The rules in the sports car world are about to be re-written.

The Inside
The heart of the new car is the Carbon MonoCell. McLaren pioneered the use of carbon composite construction in the 1981 Formula 1 MP4/1 model and set a trend that all Formula 1 teams have followed. The company brought carbon fibre to road cars for the first time with the 1993 McLaren F1 and then built on this experience with a carbon fibre chassis and body on the SLR manufactured to the same exacting standards, but in higher volumes.

Adding lightness
Weight is the enemy of performance in every area of car design. It affects acceleration, speed, handling, fuel consumption and CO2 emissions - everything. McLaren Automotive engineers pursued weight saving obsessively. Like:
  •  The Carbon MonoCell not only reduces the weight of the structure but also allows for the use of much lighter weight body panels.
  • The close position of the driver and passenger allows a narrower, lighter body while giving improved visibility with a clearer perception of the car's extremities.
  • Brakes with forged aluminium hubs save 8 kg and weigh less than optional carbon ceramic brakes.
  • Lightweight exhaust pipes exit straight out the rear of the car, minimizing their length and weight.
  • Airflow-assisted Airbrake deployment dramatically reduces weight of the Airbrake activation system.
  • Small, compact downsized engine coupled to lightweight compact SSG minimizes vehicle length, weight and polar moment of inertia.
  • Significant weight was pared off the alloy wheels through intensive Finite Element Analysis of wall thicknesses.
  • The engine cooling radiators were mounted at the rear, as close to the engine as possible, to minimize the pipework, the fluids contained within them, and therefore weight. They were also mounted in car line to minimize vehicle width.

Might expect at McLaren, everything has a purpose and the nomenclature is no exception.
    * 'MP4' has been the chassis designation for all McLaren Formula 1 cars since 1981. It stands for McLaren Project 4, resulting from the merger of Ron Dennis' Project 4 organisation with McLaren.
    * The '12' refers to McLaren's internal Vehicle Performance Index through which it rates key performance criteria both for competitors and for its own cars. The criteria combine power, weight, emissions, and aerodynamic efficiency. The coalition of all these values delivers an overall performance index that has been used as a benchmark throughout the car's development.
    * The 'C' refers to Carbon, highlighting the unique application of carbon fibre technology to the future range of McLaren sports cars.

The elements of this name represent everything that the McLaren MP4-12C stands for:
  •  'MP4' represents the racing bloodline
  •  '12' represents the focus on complete performance and efficiency
  •  'C' represents the revolutionary Carbon MonoCell

A carbon fibre heart
Light weight and performance are defining philosophies at McLaren. But outright power alone is of little significance if a car's weight saps output or if that power is unmanageable and compromises the driving experience or results in unacceptable emissions.

The Powertrain: pure McLaren
The McLaren MP4-12C is powered by a twin-turbocharged, 3.8 litre 90° V8 engine - the 'M838T'. This marks the start of a new era in 'core' segment sports cars - smaller capacity, lighter weight, higher efficiency and more economical power units. The engine has the highest specific power output in its segment which, when allied to its low weight carbon composite chassis, delivers exemplary power- and torque-to-weight ratios.

In practice the latency of the shift is virtually zero, the actual gear change time is very fast and the level of impulse can be varied according to the gearbox mode. Considering that McLaren was the first Formula 1 team to introduce seamless shift gearchanges into motor racing, it was a natural step to develop such a bespoke transmission to its sports car project.

The Chassis: Proactive control
The suspension for the McLaren MP4-12C breaks new ground, offering hitherto unseen levels of roll control and grip (an almost flat cornering attitude, depending on the programme selected).

Though such track-like responses would normally imply a rock-hard ride, the 12C delivers compliance and ride comfort more akin to an executive saloon car. The mix of occupant cosseting and sporting potential is truly unique. The 12C offers the driver both class-leading ride comfort and class-leading performance.

Inside: it all starts with the driver
McLaren designers paid great attention to all-round visibility for both safety and driving precision.
The low cowl gives a full six degrees downward vision from eye height and, importantly, allows the driver a clear view of the front of the car. The view of the top of the front wings, with the highest point positioned directly above the centre of the wheel, also facilitates perfect placement of the 12C in a corner. Rear vision is excellent too and an internal buttress with a rear three-quarter glass provides a clear rearward view.

The McLaren F1, the driver has controls on both sides, which allows for a rational positioning of switches:
  • Climate controls on each door console
  • Telematics on the upper centre console
  • Active Dynamics Panel on the middle centre console
  • Transmission and minor controls on the tunnel console
  • Trip computer and cruise controls on steering column

The Active Dynamics Panel provides two rotary switches and four push buttons:
  •  'Start/Stop'
  •  'Active' activates all the dynamic controls.
  •  'Winter' sets powertrain, suspension and electronic aids to maximum driver support.
  •  'Launch' initiates the launch control system.
  •  The two rotary switches control 'powertrain' and 'handling', each having three position settings for normal, sport and high performance driving modes.
  •  'Powertrain' changes throttle response, gearbox strategy, shift times and impulse (how much one can feel the gearchange). The coaxial 'Manual' button controls use of manual gearbox functions.
  •  'Handling' changes stability control, steering weight, suspension firmness and roll stiffness. The coaxial 'Aero' button allows the driver to deploy the airbrake for increased downforce.

The interior's simplicity belies a world-class level of comfort and safety features that will include a full quota of airbags, fully automatic dual zone climate control, sophisticated telematics and audio systems, parking sensors, trip computer, cruise control and electric memory seats.

Testing and simulation
McLaren has developed one of the most sophisticated driving simulators in the world. It is an immensely powerful tool that can be used to predict handling, performance, and a multitude of other dynamic properties.

The simulator was initially designed to improve the performance of the Formula 1 cars. But it has also been used intensively in the design and development process for the 12C, where modelling offers the opportunity to test likely outcomes without having to build a component that might turn out to be inadequate. It saves both money and time and it is perhaps the most effective technology transfer from Formula 1 to road cars; the handling and suspension of the McLaren MP4-12C was developed using exactly the same tools and techniques as the McLaren Formula 1 cars.

Production
The production process for the McLaren MP4-12C will enable McLaren to build on its recent success of record production volumes and quality for a luxury supercar with the SLR.
The McLaren Production System brings a large scale lean production mentality into a small-scale, flexible operation. The process is championed by Production Director, Alan Foster's experiences at Japanese and European car manufacturers.

Aftersales, retail distribution, personalisation
Not only is McLaren establishing a new company, a new production plant, an all-new high performance sports car engineered and developed in house... it is also building a global network of retail distribution partners.
