New McLaren 620R puts GT4 race car legally on the road

McLaren 620R

SUPERCARMAKER McLaren has announced the 620R, what it describes as ”the first car in its class to offer true motorsport credentials in a fully road-legal package”.

It’s a limited-edition coupé – only 350 will be assembled as evolutions of the competition specification of the McLaren 570S GT4 to deliver a race-car experience on either track or road.

Mike Flewitt, CEO of McLaren Auto, told The Corner in a media release: ”The McLaren 570S GT4 is a first-class GT race car. It’s won races in every championship it which it has competed since its first appearance in 2017 and is attracting a growing number of customer racing teams.

”Now, in response to repeated customer requests, we’ve homologated that class-leading package for the road in the new McLaren 620R, a limited-edition, 620PS, superlight coupé perfect for enthusiasts who want an authentic motorsport driving sensation with performance to match on track or road.”

McLaren says the 620R is a unique proposition, a pure motorsport experience in a road car. ”It looks like a race car, handles like a race car, performs like a race car, and feels like a race car.”

Guess that makes it a race car…

The automaker says the cars will keep the DNA of an homologated track car but be free of race restrictions.

The 620R has the same M838TE, 3.8-litre, twin-turbo, V8 used in the GT4 but with a significant difference in power. ”Freedom from racing regulations,” McLaren says, ”has allowed the engine ECU and turbo management to be reconfigured to achieve 620Nm to make this the most powerful Sports Series car yet.”

The engine also 592Nm and even with lap times more important than sheer top speed the combined outputs deliver benchmark performance figures of 0-100km/h in 2.8sec and 0-200km/h in 8.1sec. Top speed is 320km/h.

Fitting the GT4’s two-way manually adjustable coilover motorsport shock-absorbers, McLaren says, reduced mass slightly; the suspension uses aluminium wishbones and uprights and stiffer anti-roll bars.

The cars will have McLaren’s latest light brakes which, for track, involves carbon ceramic discs (390mm front, 380mm rear) and forged aluminum callipers all round. bBPedal response and fade resistance have been jacked up.

Braking is, McLaren says, also extremely impressive on the road on which the 620R runs Pirelli P Zero Trofeo R semi-slick tyres. However, a driver who swops to slick motorsport tyres for track ”will experience a whole new level of braking”.

The car’s aerodynamic performance, is maker says, elevates it to road-legal GT4 status. The adjustable carbon-fibre rear wing comes from the 570S GT4 and is road-legal thanks to a third brake light.


Customers will receive their car with the wing set to the least assertive of three angles for road driving. The other two can be set by a McLaren dealer for circuit time.

The rear wing is not the only component adapted from the GT4’s track specification: the front bumper, splitter and bonnet have been redesigned – the splitter retaining pronounced aero blades – while the carbon-fibre bonnet has twin nostrils to aid downforce and smooth airflow over the car.

Downforce at the front is helped by dive planes that create vortices of low-pressure air at track level and help to accelerate airflow along the car’s sides. It also aids brake-cooling.

How much? Thought you’d ask… US$299 000, or about R4.4-millon. Production will start in January 2020. Enjoy…
