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.
Black Bull Ecurie Ecosse will run one example of the 570S GT4 alongside the confirmed entry of the 650S GT3 with Factory Driver Rob Bell alongside Alaisdair McCaig.

About McLaren Automotive
McLaren Automotive is a British manufacturer of luxury, high-performance sports cars, located at the McLaren Technology Centre (MTC) in Woking, Surrey.
Following the global launch of McLaren Automotive in 2010, the groundbreaking 12C was launched in 2011, the 12C Spider in 2012, and the limited-run McLaren P1™ went into production in 2013. In keeping with its plan to introduce a new model each year, the company unveiled the 650S, in coupe and Spider form in 2014, and has announced the Sports Series among the models to be introduced in 2015. The brand continues to expand, and McLaren posted a profit during 2013 – only the third year of vehicle production. This was followed in 2014, by a third consecutive year of growth in sales with a record 1,649 vehicles delivered via a dedicated global network of retailers in every major automotive market.
Designed for the track; Developed for the road
The connection between Formula 1 and road cars at McLaren is a natural process of experience, knowledge, principles and process transfer. Through the integration of 50 years of Formula 1™ racing expertise and knowledge, and over 20 years of heritage in producing landmark sports cars, McLaren Automotive designs, develops and builds a range of technologically advanced and groundbreaking high performance sports cars which are designed to be a no compromise drive on both road and track.
McLaren has pioneered the use of carbon fibre in vehicle production over the past 30 years, and since introducing a carbon chassis into racing and road cars with the 1981 McLaren MP4/1 and 1993 McLaren F1 respectively, McLaren has not built a car without a carbon fibre chassis.
