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.
Mark Williams said: "With the tyre grip balance moving forward on the GT3 racing tyres it was necessary to move the centre of gravity further forward and the only way to do this was to reduce weight at the rear. A six-speed sequential shift gearbox by Ricardo was selected because a race-specific transmission is 80kg lighter than the Seamless Shift, seven-speed gearbox used in the road car. All the internal components have been proven in other racing series. We then challenged Ricardo to reduce weight further, meaning the unit has a bespoke casing design. That is just one example of how we are continually looking to reduce weight and increase efficiency."
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. |
