McLaren has been steadily pushing up its brand value by launching road-legal race cars that deliver actual motorsport technology to the street. Following the launch of the Senna, McLaren has now officially revealed the 620R – a road-legal race car limited to just 350 units.
At its core, the McLaren 620R is a 570S GT4 race car. The British carmaker simply homologated it for road use. It then went on to take advantage of the lack of racing regulations in street cars and made it even faster than the race version.
Race cars have regulations, road cars do not. The McLaren 620R is essentially an unrestricted 570S GT4.
To start with, the massive rear wing gets a brake light. McLaren can deliver the 620R to customers in the most roadworthy, low-downforce setting, but a McLaren retailer can adjust it to one of two other settings for increased downforce.
The front bumper and splitter are revised with more pronounced aero blades on the splitter. The car also gets dive planes to optimise air flow along the sides of the car and aid brake cooling. The 620R’s redesigned carbon fibre hood also adds more downforce to the package.
McLaren has used the same engine that powers the 570S GT4 for the 620R: a 3.8-litre twin-turbocharged V8, producing 612hp and 620Nm. The output sees the car rocket past 100kph in 2.8 seconds, topping out at 320kph.
Crucially, McLaren has retained the race car’s adjustable dampers on the roadgoing model. They are manually adjusted, and contribute to the 6-kg weight saving the 620R delivers compared to the roadgoing 570S. They feature lightweight aluminium wishbones and stiffer anti-roll bars.
Carbon ceramic rotors and forged aluminium calipers make up part of the brake setup. With the standard Pirelli P Zero Trofeo R tyres, McLaren says the 620R’s stopping power is impressive, and can be pushed even more with optional full slick tyres.
Buyers can specify what level of downforce they require from the car, out of a total of three settings.
Buyers can also choose to specify an MSO upgrade package that features a carbon fibre roof and roof scoop for the car’s intake. The McLaren Track Telemetry system is also an available extra, recording your lap times for analysis at a later time. McLaren is keeping production volume of the 620R even lower than the Senna, which was limited to 500 units. Each McLaren 620R starts at $299,000 before options, and production will begin in January 2020.
