McLaren has revealed the limited-run 620R, a road-legal version of a 570S GT4 race car.
Limited to 350 examples globally, the 620R will be the most powerful model in McLaren’s Sports Series with its 3.8-litre twin-turbocharged V8 producing 456kW and 620Nm.
A seven-speed dual-clutch automatic sends power to the rear wheels. McLaren claims the car can dash from 0-100km/h in 2.9 seconds, and hit 200km/h in 8.1 seconds. The top speed is listed at 322km/h.
The 620R gets the GT4’s two-way manually adjustable coilover motorsport dampers, which feature 32 clicks of adjustment per corner to allow a driver to tailor compression and rebound rates to suit their driving style and track conditions.
The suspension also uses lightweight aluminium wishbones and uprights, and stiffer anti-roll bars and springs over the regular Sports Series range. The rubber top mounts have been swapped for solid stainless steel alternatives.
Stopping power comes from McLaren’s latest lightweight, track-focused braking system that comprises carbon-ceramic discs (390mm front, 380mm rear) and forged aluminium calipers all round.
The 620R rides on  19-inch front wheels and 20-inch rear wheels wrapped in Pirelli P Zero Trofeo R semi-slick tyres as standard.
On the inside, McLaren has removed the carpet, glovebox, air conditioning unit, infotainment screen and sound system, although the latter three can be optioned at no additional cost.
Super-lightweight carbon-fibre racing seats with six-point racing harnesses are fitted as standard, along with a red 12 o’clock marker on the steering wheel, door pull straps and extended shift paddles.
Also included is a McLaren Track Telemetry (MTT) system displayed on a centre-mounted 7.0-inch touchscreen.
Global deliveries are set to commence early in 2020, however, McLaren’s Australian arm is yet to confirm local availability and pricing. For context, in the UK pricing starts at £​250,000 including taxes, which comes in at $481,000 AUD.
