The cylinders are angled at 90 degrees with three valves per cylinder and lubricated via a dry sump system. The compression ratio is 8.8:1 and the bore and stroke is 97 mm × 92 mm (3.8 in × 3.6 in). The Lysholm-type twin-screw supercharger rotates at 23,000 rpm and produces 0.9 bar (13 psi) of boost. The compressed air is then cooled via two intercoolers. The engine generates a maximum power of 626 PS (460 kW; 617 hp) at 6,500 rpm and maximum torque of 780 N·m at 3,250 to 5,000 rpm.The engine is front-mid mounted. McLaren took the original concept car designed by Mercedes and moved the engine 1 metre behind the front bumper, and around 50 centimetres behind the front axle. They also optimised the design of the centre firewall.
