McLaren Automotive claims that the new Mp4-12C is not meant as a direct replacement for the legendary F1 but that doesn’t mean it won’t be following in its forebear’s footsteps which means that it will be hitting the racetrack to earn its pedigree. With the road going version of the world’s latest supercar now ready for consumption, the competition version hit the pavement at the Silverstone racetrack and the MIRA proving ground in Nuneaton, England.
Unlike the F1 GTR that dove right into the top-level GT1 class that was in place in 1995 when it took overall victory at Le Mans in its first outing, the new car is being prepared to FIA GT3 rules. That puts in the same class with other factory built race cars like the Audi R8 LMS, Mercedes AMG SLS GT3, BMW Z4 GT3 and of course the Porsche 911 GT3R.
The F1 GTR’s 6.0-liter BMW-built V12 engine produced about 600 horsepower, a little less than the road car. In street-legal form, the Mp4-12C’s twin-turbo 3.8-liter V8 also produces 600 hp. However, the mandatory air-intake restrictors will likely limit the GT3-spec model to somewhere between 400 and 450 hp. The standard seven-speed dual-clutch gearbox is swapped out for a Ricardo designed and built racing unit actuated by a bespoke paddle shift mechanism.
The road car’s single-piece carbon fiber tub is retained as is the basic suspension system. The ProActive Chassis control system that uses a hydraulic interconnect system to manage body roll is replaced by a more conventional anti-roll-bar configuration while a custom Akebono braking system handles deceleration duties.
The basic appearance of the production 12C is carried over with the usual modifications to enhance aerodynamic downforce and enclose the larger racing rubber. A front splitter, extended wheel arches and vertical blades behind the front wheels are complemented by fender-top vents, a wing and rear diffuser.
CRS Racing is working with the factory engineers to test and develop the GT3 car and Álvaro Parente has been named as the first test driver. Teams interested in acquiring and racing the McLaren GT3 can sign up at www.mclarengt.com. No pricing has been announced but it certainly won’t come cheap with price tag that will surely top $500,000. Now if only the American Le Mans Series would add a full GT3 class so we could see these amazing machines run in North America.
