The 2021 BMW M5 is powered by the S63 4.4-liter TwinPower turbocharged V8 engine producing 600 hp @ 6,000 rpm and 553 ft-lbs. of torque from 1,800 – 5,690 rpm. The M5 Sedan accelerates from 0 to 60 mph in 3.2 seconds and reaches an electronically limited top speed of 155 mph (190 mph when equipped with the optional M Driver’s Package).
The M5 Competition Sedan’s engine tuning increases power to 617 hp @ 6,000 rpm and offers a 170 rpm-wider torque band, 553 ft-lbs. @ 1,800 – 5,860 rpm. The Competition model accelerates from 0 to 60 mph in 3.1 seconds and reaches an electronically limited top speed of 155 mph (190 mph when equipped with the optional M Driver’s Package).
The engine features two-turbochargers, cross-bank exhaust manifolds, direct injection and upgraded cooling and oil supply. The cross-bank exhaust manifolds improve turbocharger and throttle response by reducing the distance the exhaust gases need to flow to reach the turbochargers. Water-to-air intercooling helps reduce the temperature of the incoming air for improved power.
The advanced cooling system is composed of two separate water circuits, one for the intercoolers and one for the engine and turbochargers. An electric cooling pump ensures that the turbochargers receive sufficient coolant flow even after the engine has been turned off. An additional engine oil cooler and transmission oil cooler ensure the M5 is capable of standing up to the higher thermal demands of track driving. The oil supply system features a secondary front chamber in the oil pan which is accessed by a map-controlled oil suction pump to insure effective oil supply during extreme lateral and longitudinal forces.
