Launched as a track-focused alternative to its 570S ‘Super Series’ sports car in March 2016, the new GT4 shares the same 3.8-litre ‘M838TE’ twin-turbo V8 as its road-going, 562bhp brethren, albeit with power detuned to around 430bhp in-keeping with Balance of Performance regulations. Both also share the same ultra-lightweight, ultra-rigid ‘MonoCell II’ chassis, a development of the innovative carbon fibre monocoque McLaren first introduced to the world with the MP4-12C back in 2011. And both, according to Frans, are also inherent strengths of the 570S GT4.
“Actually the chassis is very strong and the engine is strong too. We’ve already driven more than 20,000km with one engine, so you could call both of them ‘bullet proof’. There are still a few things we have to improve but we will manage that too. I know that for sure!”
The dihedral doors remain untouched aside from selective weight saving, but the reprofiled bodywork, complete with additional aluminium construct, now includes a competition-spec rear wing mounted on aluminium pylons and a sweeping rear flank that canvases a wider rear track (traction is key!) and new 18-inch, centre-locking magnesium alloys. On top of that, adjustable dampers with coil-over springs, a brand-new floor, and a larger front splitter emphasize the GT4’s “pure focus on laptimes”. Endurance, of sorts, has also been taken into account courtesy of an extra radiator beneath the ‘GT3-inspired’ bonnet to improve cooling.
