McLaren 570S GT4
The track-only 570S GT4 shares the carbon fibre MonoCell II chassis architecture with the other models in the Sports Series. This marks the first time the technology has been made available in the GT4 category, and the race-derived material is of clear benefit with inherent strength and light weight. Driver protection is further enhanced with the addition of an FIA-approved rollcage and fire extinguisher system. Carbon fibre and aluminium are used for the reprofiled bodywork, which is formed over wider track both front and rear to accommodate centre-locking lightweight cast magnesium alloy wheels shod with slick Pirelli racing tyres. Two-way adjustable motorsport dampers with coil-over springs are fitted front and rear, and an on-board air jacking system is fitted as standard.
With a pure focus on laptimes, the 570S GT4 features a unique aerodynamic package which includes a GT4-specification high level rear wing, mounted on aluminium pylons, a larger front splitter and reprofiled floor assembly. An additional front centre high temperature radiator sits below a GT3-inspired bonnet with radiator exit ducts. These upgrades have been designed to optimise the aerodynamic performance and cooling of the 570S GT4 to ensure it is able to perform in the harshest race conditions globally.
The McLaren designed and developed 3.8-litre twin turbo V8 M838TE engine is carried over from the road-going Sports Series model. The seven-speed seamless shift gearbox is also familiar to the other models in the range, transferring power to the track via the rear wheels.
