McLaren has revealed the 620R, which they say is “the first car in its class to offer true motorsport credentials in a fully road-legal package”. The limited-edition coupé builds on the competition specification of the McLaren 570S GT4 to deliver a race-car like experience on either track or road, and for the sake of exclusivity, just 350 of them will be built.
“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.” says Mike Flewitt, Chief Executive Officer, McLaren Automotive.
The McLaren 620R looks like a race car, handles like a race car, performs like a race car and feels like a race car, resulting in a seamless transition from race to road and vice versa. It shares the same lightweight single-piece carbon-fiber Monocell II chassis as the 570S GT4, with a targeted dry weight of 1,282 kg. Adjustable aerodynamic elements, race-derived suspension components, and powertrain recalibration help to increase power and performance, further enhancing the 620R’s driving and handling dynamics.
The 620R has the same M838TE 3.8-litre twin-turbocharged V8 engine used in the GT4 car, but with a significant boost 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 620Nm of torque. The 0-100km/h sprint takes just 2.9 seconds and 0-200km/h is achieved in 8.1 seconds. Maximum speed is 322km/h.
Power is sent through a seven-speed Seamless Shift Gearbox (SSG) which delivers super-fast shift times, ideal for setting blistering lap 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, selecting Sport mode allows the driver to hear the upshift ‘crack’ created by a split-second cut of the ignition spark during a gearshift.
The 620R also makes use of the GT4’s two-way manually adjustable coil-over 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 dampers also help to make the 620R lighter overall, being more than 6kg lighter than the regular Sports Series units. The suspension also features lightweight aluminium wishbones and uprights, and stiffer anti-roll bars and springs than those fitted on any regular Sports Series model. Even the regular rubber top mounts have been swapped out for solid stainless steel alternatives to provide noticeable improvements in steering control and feedback
An adjustable carbon-fiber rear wing (same as the one used on the 570 GT4) raised 12.5 inches into the cleaner airflow above the vehicle increases downforce while minimizing drag, which is now road legal thanks to McLaren incorporating a third brake light. The front bumper, splitter and bonnet have also been redesigned – the splitter retaining pronounced aero blades and cut-out – while the carbon fibre bonnet has twin nostrils to aid downforce and clean up the airflow over the top of the car. All these more aggressive angles help develop a total of 185 kg of downforce across the aerodynamic bodywork at 250 km/h.
Stopping power comes from McLaren’s latest lightweight braking system, comprising of carbon ceramic discs (390mm front, 380mm rear) and forged aluminium brake calipers all round, with improved pedal response, modularity and resistance to fade even after repeated hard-driven circuit laps. As standard, the 620R runs on Pirelli P Zero Trofeo R semi-slick tires, but drivers can choose to swap them out with optional, full-slick motorsport tires for track driving. McLaren says the specially developed tyres unlock a contact patch 8% larger than that of the road tyre, increasing lateral G-forces and enabling quicker lap times. This is the first time that a road-legal car with 19-inch front wheels and 20-inch rear wheels has been engineered to be able to run on slick tires without the need for additional mechanical adjustment.
However, if you were hoping that it would be oozing in McLaren luxury, you’d be wrong. Make no mistake, this is a stripped out race car, for the road. The 620R does not have a floor carpet or a glovebox. There is no Air-conditioning, IRIS Navigation and an audio system are also missing from the standard specification, although all can be selected at no additional cost. A lightweight Bowers & Wilkins upgraded audio system is also available, as a cost option.
The driver and passenger sit in super-lightweight carbon fiber racing seats with six-point racing harnesses, fitted as standard. Structural carbon fibre elements such as extended shift paddles, steering wheel spokes and centre console enhance the sense of being in the cabin of a race car. A McLaren Track Telemetry (MTT) system comes as standard and is displayed on the center-mounted seven-inch touchscreen.
Each 620R also features a unique dedication plaque on the centre console with numerical identification (1 of 350; 2 of 350, etc). Each 620R can be configured to be distinctively individual, as with every McLaren road car. Single elements, for example the colour of the brake calipers, can be chosen as a solus specification; alternatively, buyers can opt for upgrade packs such as the Gloss Finish Visual Carbon Fibre Exterior Pack, which adds visual drama to everything from the side intakes to the door mirror casings. McLaren Special Operations (MSO) provides further personalisation choices, with a range of MSO Defined Exterior options that includes a titanium SuperSports Exhaust with Nano Black Exhaust Finisher and MSO Defined interior upgrades that incorporate a choice of harness colour.
Three colours are available inspired by the 570S: McLaren Orange (with white racing stripes), Silica White (orange stripes) and Onyx Black (orange stripes). Each can be optioned with race number decals and/or partner decals. Further body colours are available in the MSO line-build palette. An even more exclusive decal livery inspired by the McLaren Senna GTR is also available.
