McLaren Automotive has announced two new track-dedicated models of the recently-launched Sports Series: the 570S GT4 and the 570S Sprint. The two cars have been developed in conjunction with McLaren GT – the motorsport division of McLaren Automotive – and GT racing specialists, CRS GT Limited.
McLaren GT and CRS GT Limited will work with Black Bull Ecurie Ecosse, with the 570S GT4 competing in the full nine round calendar, including the famous Spa-Francorchamps. The program will be a rigorous testing schedule in live race environments. The 570S Sprint, will be dedicated for private trackdays and is therefore unrestricted by racing regulations. However, 570S Sprint owners will be able to upgrade to GT4 specification.
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 fiber and aluminum are used for the bodywork, which is formed over wider track both front and rear to accommodate center-locking lightweight cast magnesium alloy wheels shod with slick Pirelli racing tires. 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 aluminum pylons, a larger front splitter and reprofiled floor assembly. An additional front center high temperature radiator sits below a GT3-inspired bonnet with radiator exit ducts. These upgrades have been designed to optimize 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.
McLaren said the 570S GT4 will be homologated for all GT4 racing in 2017 and will cost around $226,853 (159,900 GBP).
From the 570S GT4, McLaren will also develop the 570S Sprint, which will be unimpeded by homologation rules but upgradable to GT4 spec if the customer desires. McLaren isn’t offering any details on the 570S Sprint yet, but expect a car similar to the 650S Sprint, which debuted in 2014.
