Meet the McLaren 570S GT4 and 570S Sprint
The most recent news surrounding McLaren are their rather spectacular road cars, starting with the 12C and onto to the 675LT and P1 hypercar. Putting their current struggles with Formula 1 to one side, McLaren has been quiet on the racing front over the past few months.
But now British supercar brand has rolled out its track variants for their 570S, called the GT4 and Sprint. Prior to this, there was lighter and harder versions too such as the 650S GT3 and P1 GTR. Now it’s the baby-Maccer’s turn.
Let’s look at the 570S GT4, for which McLaren turned to outside help to make a reality. The McLaren GT division helmed its development with CRS GT Limited to make sure it complies with the lower-tier FIA racing regulations.
There has obviously been some considerable fettling over the road-going 570S, however those are limited to the body and chassis but not the powertrain, which a 3.8-litre twin-turbo V8 developing 519kW sent to the rear wheels via a 7-speed Graziano-developed dual-clutch transmission.
The car has a wider track for more nimble handling, and the new carbon and aluminium panels are made to accommodate the extra girth, supplementing the slick racing tyres from Pirelli attached to lightweight centre-locking magnesium alloy wheels.
The suspension has been extensively reworked for the GT4, which is both a mechanical and calibration exercise. It has adjustable dampers, front and rear coil-over springs, and an on-board air jacking system.
Aerodynamics has been given a once-over as well, with a fixed rear wing, larger front splitter and reprofiled floor assembly. There’s also a front centre high temperature radiator to ensure the engine stays optimally cooled during unrelentingly harsh racing conditions.
On to the 570S Sprint, which will be a lot like the 570S GT4 but with reduced extremity due to it not having to conform to the FIA’s racing regulations. Aimed at track enthusiasts who wants a more raw 570S, the Sprint will still have the suspension and the majority of aero tweaks of the GT4.
McLaren say they’re readying both cars for a full unveil in a few weeks time.
