Building on the success of the 12C GT3 – winner of three championship titles and 51 races over the last three years – the new 650S GT3 features improved aerodynamics, better cooling and enhanced safety. Based on the recently launched 650S road car, McLaren’s engineers have used the very latest Computational Fluid Dynamics (CFD) technology to develop the new lightweight carbon-fibre bodywork, carefully managing the airflow across, through and beneath the car. The result is a car with a huge presence, featuring a menacing new nose, re-profiled side intakes, and a new carbon-fibre fixed rear wing. Under the skin, the suspension geometry has also been completely revised, with a 52mm wider track and new wheels and tyres, ensuring improved front-end grip and drivability.
The cockpit has been thoroughly reworked: McLaren GT has listened to customer feedback within the 12C GT3 programme, and the new 650S GT3 features better refinement and driver comfort, essential factors in GT3 racing. The FIA-approved roll cage has been redesigned to improve leg and headroom; there’s a new race seat, a new Formula 1™ inspired steering wheel, a new pedal box; and driver ventilation has also been improved.
The new car produces around 500PS – the same as the 12C GT3, as the power output is governed by FIA regulations – but the McLaren ECU controlling the award-winning 3.8-litre twin-turbo V8 has been upgraded, and the engine is now coupled to a new six-speed sequential gearbox.
