McLaren Automotive has announced two new track-dedicated models of the recently-launched Sports Series: the 570S GT4 and the 570S Sprint (coming soon). Developed in conjunction with McLaren GT – the motorsport division of the McLaren Automotive – and GT racing specialists, CRS GT Limited, the 570S GT4 will now enter an intensive season-long development programme in the British GT championship.
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.
The 570S GT4 will make its public development debut at the opening round of the British GT Championship at Brands Hatch, UK over the weekend 16-17 April 2016. Going forward, it will be eligible for all GT4 homologated championships globally from the 2017 season.
