McLaren Reveals Street-Legal Version of GT4 Race Car
McLaren recently revealed the new 620R, which is based on the competition specification of the McLaren 570S GT4 race car.
The 620R has the same M838TE 3.8-liter 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 610 hp, making this the most powerful Sports Series car yet. The engine also develops torque of 457lb ft and even with lap times more important than sheer top speed, the combined outputs helps to deliver benchmark performance figures of 0-60mph in 2.8 seconds and 0-124mph in 8.1 seconds. Maximum speed is 200mph.
Fitment of the GT4’s two-way manually adjustable coilover motorsport dampers adds to the 620R’s motorsport credentials. The dampers also help to bring weight down overall, being more than 13lbs lighter than the regular Sports Series units. The suspension features lightweight aluminum wishbones and uprights and stiffer anti-roll bars.
Stopping power comes from McLaren’s latest lightweight braking system, which in the track-focused set-up on the new 620R comprises carbon ceramic discs (390mm front, 380mm rear) and forged aluminum brake calipers all round, with improved pedal response, modularity and resistance to fade even after repeated hard-driven circuit laps. The braking performance is unsurprisingly also extremely impressive on the road, where the 620R runs as standard with Pirelli P Zero Trofeo R semi-slick tires, but drivers who swap to the optional, full-slick motorsport tires when they arrive on circuit will experience a whole new level of braking.
“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,” McLaren Automotive CEO Mike Flewitt said. “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.”
