Ferocious 570S GT4 and 570S Sprint models ready to chew up the track
McLaren has just released details of its new track-dedicated 570S GT4 and 570S Sprint models, which have undergone extensive chassis and aerodynamic modifications to cater for the high demands of circuit-driving.
The 570S GT4, priced just under £160,000, is a purpose-built racer that’s been developed by McLaren GT and motorsport specialist CRS GT Ltd, while the 570S Sprint has been created as a private track-day supercar and is 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 but light-weight.
Driver protection is further enhanced with the addition of an FIA-approved roll-cage 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 lap-times, 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.
Ansar Ali, the new Motorsport Director, will be responsible for on-going strategy and management of motorsport activities. Commenting on his new appointment he said: “I am extremely proud and honoured to be joining McLaren Automotive at such a pivotal time.
“Activities on track have played such a significant part in the history of making McLaren globally recognised. The opportunity to play a major part in shaping its future motorsport strategy is extremely exciting, and the 570S GT4 and 570S Sprint models are an important initial step.”
