McLaren released new details and specs of their brand-new racer, the MP4-12C GT3. Jointly developed with CRS Racing, the car will warm up in 2011 season for full participation in endurance racing in from 2012.
For the 2012 season McLaren will build 20 MP4 GT3 for privateers. They have used Formula 1 know-how and advanced technologies to make sure they will be delivering an unrivalled race car to the customers. But that’s not completely true, because there are going to be 20 of the thing, and they can rival each other! 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.
Based on the road-going MP4, the GT3 is also one of the best looking race cars on the grid. They say it will deliver the highest quality, most reliable and most driveable car on the GT3 grid. We will soon realize what this car is all about as the debut is planned at this season’s Blancpain Endurance Series race at Spain’s Circuito de Navarra, followed by Magny-Cours in France and Silverstone in England. The car might also make an appearance at the Spa 24-hour.
Although it has the same 3.8-litre McLaren V8 twin turbo ‘M838T’ engine as the road car, but they had to de-tuned to 500 PS (from 600 PS) to meet the GT3 regulations. It gets a full carbon fiber integrated body and chassis, bespoke racing transmission developed in partnership with Ricardo and a suspension arrangement tuned specifically for racing.
