McLaren unveils a road-legal 200mph version of its 570S GT4 race car

McLaren is producing a road-legal version of its 570S GT4 race car – complete with a 2.9 seconds 0-62mph time.

The McLaren 620R has a top speed of 200mph and develops 620 horse power (hence the name).

The most powerful car in the McLaren Sports Series, it will cost from £250,000 and begins shipping to customers in the New Year.

The UK manufacturer claims the 620R is the first car in its class to offer “true motorsport credentials in a fully road-legal package”, adding:

“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.”

Under the bonnet is the same M838TE 3.8-litre twin-turbocharged V8 engine used in the GT4 car, but with a significant difference in power output.

Freed from racing regulations, McLaren’s engineers have 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) with benchmark performance figures of 0-100km/h (62mph) in 2.9 seconds and 0-200km/h (124mph) in 8.1 seconds. Top speed is 322km/h (200mph).

McLaren’s Mike Flewitt said: “The McLaren 570S GT4 is a first-class GT race car that having won races in every championship it has competed in since its first appearance in 2017 is attracting an increasing number of customer racing teams.

“Now, in response to repeated customer requests, we have homologated that class-leading package for the road in the new McLaren 620R, a limited-edition, 620PS superlight coupé that is the perfect choice for an enthusiast wanting an authentic motorsport driving sensation – and performance to match – on both track and road.”

For the new model, parts of the driving dynamics have been reconfigured, including the use of stiffer powertrain mounts to reduce drivetrain forces under acceleration, minimising the effect of inertia under high load.

The 7-speed Seamless Shift Gearbox (SSG) is further aided in Track mode 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, says McLaren.

A range of other features include stiffer powertrain mounts, an adjustable carbon fibre rear wing and adjustable coil-over motorsport dampers featuring 32 individual settings per corner.

McLaren says this is the first time a road-legal car with 19-inch front wheels and 20-inch rear wheels has been engineered to be able to run on slick tyres without the need for additional mechanical adjustment.

Production of the 620R is limited to 350, all hand-built at the McLaren Production Centre in Woking, Surrey.

Production begins in January, with delivery expected to begin the following month. For buyers purchasing in Europe and the USA, the price includes a Pure McLaren Track Day, with expert driving tuition at a race circuit.
