The 650S GT3 is equipped with the latest generation of the award-winning, 3.8-litre McLaren V8 twin turbo ‘M838T’ engine. Race-prepared and including a McLaren-developed ECU offering increased functionality to incorporate turbo boost and transmission shift control, the engine is coupled to an all-new six-speed sequential motorsport transmission. The 650S GT3 produces around 500PS – the same power as the 12C GT3, which is controlled by the FIA’s Balance of Performance (BOP) regulations. Cooling is improved through larger 650S intakes within the front bumper and re-profiled side intakes. In addition to this, the gearbox oil cooler has been relocated, now incorporated into the larger side intakes, giving the rear of the car a cleaner, more aerodynamic flow.
The 650S GT3 development programme has pulled significant data from the findings and lessons learned from the 12C GT3 programme. Testing of the 650S GT3 will continue throughout the summer with customer car production commencing in the autumn. Pricing for the 650S GT3 has been confirmed – £330,000 (Rs. 3.37 crore) ex works, plus tax.
Existing owners of the 12C GT3 are also able to benefit from the updates and enhancements offered by the 650S GT3, due to the use of the shared chassis structure and award winning engine. This upgrade package further extends the life of existing 12C GT3 cars allowing them to continue racing competitively through a second GT racing life cycle. For many McLaren GT3 owners this allows them to race their existing car for an average of six seasons.
Around 15 examples of the 650S GT3 are planned to be produced and delivered for the start of the 2015 season. With the optional upgrade package for 12C GT3, this could see an additional 15 cars running the new design from next season.
