‘You think that’s a racecar?’

570 GT4 racer vs 600LT

Race relation

570 GT4 is the racing alter-ego of McLaren’s 540/570/600 Sports Series road cars, available for private customers and race teams to buy for £159,900 ex-works.

Basically the same

GT4 racer is closely based on McLaren’s Sports Series road cars: same carbon tub, same dual-clutch ’box and 3.8-litre twin-turbo V8, with race-spec mapping.

Performance balanced

In international racing the GT4 is hamstrung by 110kg of ballast, as part of the Balance of Performance regulations intended to make racing closer, but competes without in the Pure McLaren series.

Neutered

Road car is tuned to 592bhp, and develops 457lb ft of torque, but the racer is limited to 358lb ft by GT4 regulations, and its throttle restricted by 50 per cent.

Race-bred vs a racer

600LT road car is the most extreme car to date in the Sports Series, McLaren’s most accessible range. It’s road-legal, but optimised for the track. Yours for £185,500.
