McLaren’s new 570S is now available to order, completing McLaren’s plans for a three-part car range.

The car uses McLaren’s familiar 3.8-liter twin-turbo V8 engine, which produces less power than in the 650S but has a range of new components.

Engineered by McLaren and built by Ricardo at its Shoreham facility on the south coast of the UK, the engine produces 570ps at 7,400rpm and 600Nm of torque at 5,000-6,500rpm, 80ps and 80Nm lower than in the 650S.

McLaren says, however, that 30% of the components on the engine are bespoke to the car, such that the engine receives its own code – M838TE, with the E standing for evolution.

The car is the first in McLaren’s new line of ‘sport series’ cars, not to be confused with the 650S’s ‘super series’ status. The three-part McLaren range is topped by the P1’s ‘ultimate series’ designation.

The 570S features stop/start technology for the first time on a McLaren, aimed at providing greater efficiency during city driving, improving fuel consumption and CO₂ output. The car returns 22mpg on the EU combined cycle, with emissions of 249g/km.

Other improvements to the powertrain’s efficiency include new 60-degree camshaft phase controllers that reduce internal engine inertia and provide greater control, both benefitting CO₂ figures and engine response. The vacuum system has also been deleted from the engine which saves 2.5kg and reduces complexity.

The 570S is also fitted with new equal length exhaust manifolds produced from cast stainless steel mounting sections mated to stainless steel hydroformed tubes, which are designed to optimize exhaust flow and provide consistent, uniform back pressure and a new exhaust note.
