McLaren MP4-12C GT3: full details
McLaren MP4-12C GT3 will be the first car from the manufacturer built for FIA GT series racing since the famous McLaren F1 GTR. The iconic F1 finished production in1997. 12C GT3 is based on the new MP4-12C, which is one of the best super sports cars in the world.
"McLaren has racing in its blood and it was a natural step to take our MP4-12C road car and turn it into the most reliable, efficient and easy to drive GT3 car. Every car on the grid will have its performance balanced by race rules, meaning our objective must be to select a technical specification that ensures any driver is able to access the 12C GT3's performance limit with ease.", commented Martin Whitmarsh, McLaren Group Chief Executive Officer.
The 12C GT3 made its race debut at the UK circuit – Silverstone. Just a week after, the car was sent to the Circuito de Navarra in Spain for its first FIA circuit test. In simulated tests, McLaren GT was able to fine-tune engine calibration, power steering, spring rates, weight distribution, gear ratios and differential settings.
McLaren MP4-12C GT3 comes with a new aerodynamics package, which is made entirely from carbon fibre. It is specially created by McLaren Racing in compliance with GT3 regulations. The body kit includes - a new front splitter, door blade, rear wing, diffuser and louvres in the front fenders.
MP4-12C GT3 has the same 3.8-litre McLaren V8 twin-turbo M838T engine as the road car, but it will be de-tuned to 500PS (from 600PS) in order to provide optimum power for this performance-balanced race car. The car also includes the TAG-400 Engine Control Unit, which is a compact, self-contained engine management system and data logger for race engines designed and built by McLaren Electronic Systems.
Other very important features are the unique engine calibration, bespoke racing transmission developed in partnership with Ricardo and a suspension arrangement tuned specifically for racing.
