The high-revving V8 engine presents a compelling blend of razor-sharp responses, a feverish appetite for revs and sustained power delivery across an extraordinarily wide rev band. The M TwinPower Turbo technology of the 4.4-litre unit includes a pair of turbochargers – positioned in the “V” between the cylinder banks and boasting optimised efficiency – and indirect charge air cooling, plus a direct fuel injection system working with maximum pressure of 350 bar. Another technological highlight is the cross-bank exhaust manifolds.

In the new BMW M8 Coupe and new BMW M8 Convertible, the engine serves up peak torque of 750 Nm (553 lb-ft) between 1,800 and 5,600 rpm – and goes on to deliver maximum output of 441 kW/600 hp at 6,000 rpm, en route to the 7,200 rpm cut-off. The power unit in the Competition models sustains its peak torque up to 5,800 rpm and develops maximum output of 460 kW/625 hp at 6,000 rpm, its race-derived, high-revving instincts taking an even more prominent lead. The most powerful variant of the V8 teams up with a special engine mounting for a more rigid connection with the vehicle structure. This results in even crisper engine response and also has a positive effect on the immediacy of turn-in and the transmission of engine noise into the cabin.

A sophisticated cooling system ensures optimum operating temperatures at all times, both in everyday use on urban routes and when the cars are stretching their legs on the track. The central cooling module, for example, is flanked by two high-temperature water circuits. And the system also features an additional engine oil cooler and separate transmission oil cooler. The particular challenges of track driving are reflected in the design of the oil supply system. The oil sump has a smaller front chamber, which steps in when extra capacity is needed. An additional suction stage allows the map-controlled oil pump to draw lubricant from the smaller chamber. This ensures a reliable supply of oil at all times, even under extreme lateral and longitudinal acceleration.
