All of this is sent through a seven-speed dual-clutch auto transmission with rear-wheel drive.
The interior of the vehicle uses lightweight carbon fiber racing seats with both 6-point harnesses and road seat belts. The two cars share the same chassis, a single-piece, carbon-fiber structure known as "Monocell II" - in the 570S only the roof is aluminum. Just like in the GT4, you get two-way manually adjustable coilovers, with 32 clicks of adjustment for the damping rates - and the hardware changes the suspension lighter than the road version, contributing a 6kg saving from the total. McLaren state that the 620R is set up to allow owners to either fit a new set of slicks to the standard rims or to switch to a new set quickly, upon arrival at the track. For the most part, the bodywork is identical too.
In front, the front bumper, splitter and bonnet have been redesigned; the splitter retains its aero blades and cut-out while the carbon-fibre bonnet employs twin "nostrils" to aid downforce and clean up airflow over the top of the auto.More news: 'Parasite' Takes Earns Top Awards from L.A.

The changes to the suspension continue with aluminium wishbones and uprights and stiffer anti-roll bars and springs. There's also standard Pirelli P Zero Trofeo R semi-slicks, with full slicks an option if you want to head to the race track.
While interior pics are conspicuous by their absence, McLaren tells us the 620R is shorn of carpets, with aircon, satnav and an audio system all available as no-cost options.
Stopping is courtesy of 390mm front and 380mm rear carbon ceramics discs that work with forged aluminium calipers - which, tellingly, have been engineered with a focus on providing optimum feel and performance when they're subjected to track work. The McLaren 620R is nearly as quick as a 488 Pista, despite arriving with 90 hp less.More news: Reasons Not to Install Galaxy S10 Android 10 & 9 Reasons You Should
In case the hardcore focus of the auto wasn't already obvious, McLaren has fitted the 620R with lightweight carbon-fibre bucket seats, six-point harnesses, red 12 o'clock steering wheel marker, door pull straps and carbon-fibre trim aplenty.
McLaren Automotive chief executive officer Mike Flewitt said the 570S GT4 had won races in every championship it had competed in since its first appearance in 2017.
"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 coupe that is the flawless choice for an enthusiast wanting an authentic motorsport driving sensation - and performance to match - on both track and road". Apparently, the 620R series will consist of 350 units priced starting from £250,000. That price includes a Pure McLaren track day, with expert tuition for your purchase. The build slots start in January 2020, with first deliveries expected the following month.More news: Rohingya activists launch boycott of Myanmar
