<< Prev Page 2 of 2  Inside the cockpit, the 650S GT3 provides improved levels safety for the driver. Protection offered by the carbon fibre MonoCell chassis is further enhanced with the addition of an FIA-approved rollcage. Redesigned and lighter than that of the 12C GT3, the 650S GT3 rollcage provides a greater degree of driver comfort, with increased leg and headroom.Another key area that has been optimised is the level of refinement, underlining the focus on endurance and driver engagement. As with its predecessor, the 650S GT3 is fitted with a bespoke motorsport digital dash display which sits behind the unique 650S GT3 steering wheel, inspired by the wheel design seen in the McLaren Mercedes Formula 1 car. New to the 650S GT3 is a fully FIA-approved McLaren GT-developed race seat, fitted with a six-point race harness as standard. This seat offers increased levels of support and driver comfort through the use of bespoke moulded seat inserts. The layout within the cockpit has been revised to make it even more driver-focused than previously. The seat is directly mounted to the chassis, and the steering wheel and all-new motorsport pedalbox are then adjustable to bring them closer to the driver. The centre console is also developed from the latest 12C GT3 interior, reducing complexity, and features a membrane-type switch panel for ease of use. In addition to this, improvements have been made to further optimise ventilation and driver cooling. 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 uses an all-new race-tuned suspension system with a 52mm wider track than the 12C GT3. The front suspension also allows the fitment of the latest generation larger diameter racing tyres . In conjunction with the optimised aerodynamic package, this provides increased levels of front-end grip and steering feel on turn-in. Newly designed forged aluminium wheels (front - 12.5" x 18", rear - 13" x 18") are held in place with a single wheel retaining nut on motorsport axles, while a revised hub bearing assembly and extended-life suspension components are another example of a simplified service item, and reduced maintenance costs. Behind the new design eight-spoke wheels, and bringing the power, aerodynamics and downforce under control is a newly-developed braking system with monoblock six-piston callipers on the front, and four-piston on the rear, with ventilated discs (380 x 35mm front / 355 x 32mm rear). 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 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. << Prev Page 2 of 2 |
