New McLaren 620R sets the Pace as road legal version of McLaren GT4 Race car

McLaren today announces the 620R, the first car in its class to offer true motorsport credentials in a fully road-legal package. The limited-edition coupé – just 350 will be built – evolves the competition specification of the McLaren 570S GT4 to deliver a race-car experience on either track or road.

McLaren has enjoyed significant GT race success with Customer Racing teams and in recent seasons the 570S GT4 has been instrumental in adding to that record of success. Since the customer debut in 2017, the car has become the most successful GT race car built by McLaren, achieving more race wins and podiums than any other to date; in 2019, the 570S GT4 has competed in championships on four continents. Now, as the ultimate track-focused, track-ready but roadgoing McLaren Sports Series model, the McLaren 620R – a car destined to be both rare and collectable, thanks to its strictly limited production run – celebrates the achievements of the 570S GT4.

The McLaren 620R is a unique proposition, delivering a pure motorsport experience in a road car with authenticity: it looks like a race car, handles like a race car, performs like a race car and feels like a race car. The result overall is a seamless transition from race to road – and vice versa. Exclusive and extreme in equal measure, the McLaren 620R retains the DNA of a fully homologated track car yet is free from the restrictions that race regulations apply.

A high level of commonality with a 570S GT4 race car has been integral to the development of the 620R from very outset. They have the same, single-piece carbon fibre Monocell II chassis providing the foundations for the strength and light weight of the car, with a targeted lightest dry weight of 1,282kg. This carbon fibre core – a McLaren signature that in different guises features in every car in the company’s range – also underpins the dynamic precision and composure for which McLarens are renowned. These characteristics have been enhanced in the 620R by the inclusion of the GT4’s adjustable aerodynamic elements, race-derived suspension components and powertrain recalibration to increase power and performance.

The 620R has the same M838TE 3.8-litre twin-turbocharged V8 engine used in the GT4 car, but with a significant difference in power output; freedom from racing regulations has allowed the engine ECU and turbocharger management to be reconfigured to achieve 620PS (610bhp), making this the most powerful Sports Series car yet. The engine also develops torque of 620Nm (457lb ft) and even with lap times more important than sheer top speed, the combined outputs helps to deliver benchmark performance figures of 0-100km/h (62mph) in 2.9 seconds and 0-200km/h (124mph) in 8.1 seconds. Maximum speed is 322km/h (200mph).

The use of stiffer powertrain mounts reduces drivetrain forces under acceleration, minimising the effect of inertia under high load, while the 7-speed Seamless Shift Gearbox (SSG) delivers super-fast shift times, further aided in Track model by McLaren’s Inertia Push technology, which converts built-up flywheel energy into a momentary burst of torque on upshift. For added drama on the road the driver can select Sport mode and hear the upshift ‘crack’ created by a split-second cut of the ignition spark during a gearshift.

Fitment of 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, adds to the 620R’s motorsport credentials. The dampers also help to bring weight down overall, being more than 6kg lighter than the regular Sports Series units.

The suspension which features lightweight aluminium wishbones and uprights and stiffer anti-roll bars and springs than fitted on a regular Sports Series model, is further enhanced by swapping rubber top mounts for solid stainless steel alternatives to provide noticeable improvements in steering control and feedback, above and beyond the very high standards enjoyed in all McLaren cars.
