As expected, McLaren revealed at the 2014 Goodwood Festival of Speed the all-new 650S GT3. This new race car promises to continue the success of the 12C GT3 and it is built around the same lightweight carbon fiber MonoCell chassis. Regarding the design, the 650S GT3 comes with the GT3 iteration honed using CFD technology.
As a result, the vehicle features an aggressive front splitter, larger air intakes, new lightweight carbon fiber bodywork wraps around reprofiled air intakes but also a new rear carbon fiber wing that works in tandem with the large carbon fiber splitter.
In addition, the 650S GT3 features revised suspension geometry, wider track and an updated overall setup. A priority when developing the brand new 650S GT3 was reducing cost of ownership and according to McLaren this was achieved thanks to extended component life, including increased engine and gearbox rebuild intervals, but also thanks to the redesigned components and systems.
Inside, the vehicle features a FIA-approved rollcage that was redesigned and it is lighter than that of the 12C GT3. The steering wheel is inspired by the one found on the McLaren Mercedes Formula 1 car.
Also new are the FIA-approved McLaren GT-developed race seat that is fitted with a six-point race harness as standard. The seat is directly mounted on the chassis, while the steering wheel and new motorsport pedalbox are adjustable. Power comes from the 3.8-liter McLaren V8 twin-turbo engine that produces around 500 PS, less than the street version and the same as the 12C GT3.
McLaren prepared the engine for racing and included a newly-developed ECU that offers increased functionality in order to incorporate turbo boost and transmission shift control. The engine is bolted to a new six-speed sequential motorsport transmission, which delivers the power to the rear wheels.
Compared to the 12C GT3, the 650S GT2 comes with a new race-tuned suspension system with a 52 mm wider track. Moreover, the front suspension allows the fitment of the latest generation large diameter racing tyres and the newly developed aluminum 18-inch aluminum wheels.
Behind the eight-spoke wheels, we find a new braking system with monoblock six-piston calipers on the front and four-piston on the rear, with ventilated discs (380 x 35mm front / 355 x 32mm rear).
The British carmaker announced that the existing 12C GT3 owners can benefit from the updates and enhancements of the 650S GT3. According to McLaren, around 15 units of the 650S GT3 will be built and delivered for the 2015 season, each priced at £330,000 ($562,000 / 413,000 euros) ex works, plus tax. [source: McLaren]
