The engine produces maximum power of 562bhp (which equates to 570PS and informs the car’s name) and 443lb ft of torque. It has been given the designation M838T E, with the ‘E’ standing for ‘evolution’.
The 570S Coupé can cover 0-62mph in 3.2sec and 0-124mph in 9.5sec, going on to a top speed of 204mph. The new McLaren can reach 100mph in 6.3 seconds.
By comparison, the £137,500 R8 V10 Plus has maximum power of 601bhp and peak torque of 413lb ft from its naturally aspirated 5.2-litre engine. Official figures indicate that the all-wheel-drive Audi can match the McLaren from 0-62mph but is 0.4sec slower to 124mph and has a claimed 205mph top speed.
Prices for the 911 Turbo S start at £142,120. With 552bhp and 516lb ft on tap from its twin-turbocharged 3.8-litre flat six, the all-wheel-drive Porsche pips its rivals from 0-62mph, taking 3.1sec. It hits 124mph in 10.3sec and its top speed is 194mph.
One of the key features of the new McLaren is its comparatively low weight. With the 570S Coupé tipping the scales at a claimed 1313kg - about 150kg lighter than the R8 V10 Plus - it has a class-leading power-to-weight ratio of 428bhp per tonne.
Crucial to the low weight is a new design of McLaren’s carbonfibre MonoCell II chassis, tweaked from the version used in the 650S. The 570S’s structure weighs less than 80kg and, in line with the new car’s focus on usability, it has modified sills to make it easier to get in and out of the cabin.
The sophisticated interlinked suspension that is a feature of the 650S has been replaced on the 570S with a more standard double wishbone design paired with adaptive dampers and anti-roll bars. As with the 650S, though, the powertrain and handling settings can still be switched between progressively more focused Normal, Sport and Track modes.
McLaren claims fuel economy of 25.5mpg and CO2 emissions of 258g/km for the 570S. The R8 V10 Plus returns a claimed 23.9mpg and the 911 Turbo S a claimed 29.1mpg. The 570S is slightly larger than the 650S in each key dimension, being 4530mm long, 2095mm wide and 1202mm tall.
The 570S is clad in aluminium bodywork, which, McLaren says, allows for an intricate panel design. The car retains key elements of the McLaren family look, such as the P1-derived front and rear lights.
There are broad similarities in shape and stance, which are largely informed by cooling considerations, but the 570S shares no panels with other McLaren models. Instead, it has bespoke aerodynamic styling features, such as the front aero blades, side skirts and rear diffuser.
Aerodynamic devices such as the rear wing are fixed, rather than active. The door tendons are inspired by the P1 and they channel cooling air into the engine bay.
It is aft of the cabin where the 570S Coupé looks significantly different from other McLaren models. In place of the 650S’s long rear glass engine cover, the new model features a ‘flying buttress’ pillar design, together with a vertical glass rear window and an engine cover that fits snugly over the V8 powerplant.
The new model is designed to provide “day-to-day usability and driveability” compared with McLaren’s more extreme offerings. There’s a greater emphasis on interior comfort, with additional stowage in the cabin, leather upholstery and a best-in-class front luggage capacity of 144 litres.
