Thirty five years after the debut of the first BMW M3, BMW has presented the latest generation of its high-performance models that fuse track-focused performance with everyday usability.
The new BMW M3 Competition Saloon and new BMW M4 Competition Coupé occupy very different territory - one a saloon with space for five occupants, the other a four-seater coupé - but they both achieve their common goal of delivering pure driving pleasure.
Class-leading levels of standard equipment plus options that take individualisation to new heights, especially for racetrack outings, ensure both models will continue the success of their formidable predecessors.
Optional equipment is offered in six main packages - Comfort, Technology Plus, Visibility, M Carbon, M Pro and Ultimate. Beyond these packages, there will be a select number of optional items including M Brakes in red, blue or black, M Carbon exterior, M Carbon seats and Park Assistant Plus with Drive Recorder.
Under the bonnet of the new BMW M3 Competition Saloon and new BMW M4 Competition Coupé lies a 510hp high-revving straight-six engine with M TwinPower Turbo technology, which teams up with an eight-speed M Steptronic transmission as it sends its power to the rear wheels.
Both models will also be available (from summer 2021) with M xDrive, which offers even greater directional stability and supreme traction without compromising on agility.
The new BMW M3 Competition Saloon is built at BMW Plant Munich, while the new BMW M4 Competition Coupé is produced at BMW Plant Dingolfing. The market launch in the UK for both models is Saturday 13 March, 2021.
Bespoke M TwinPower Turbo technology
A bespoke version of M TwinPower Turbo technology includes two mono-scroll turbochargers that supply compressed air to cylinders 1-3 and 4-6 respectively. An indirect intercooler optimises the power output of the charger and its electronically controlled wastegate supports the turbochargers' instantaneous responsiveness and heightens the effectiveness of the catalytic converters.
Other elements of M TwinPower Turbo technology include VALVETRONIC variable valve timing and Double-VANOS variable camshaft timing. Both models meet the Euro 6d exhaust emissions standard.
Cooling system and oil supply designed for track use
The new BMW M3 Competition Saloon and new BMW M4 Competition Coupé use a bespoke cooling system to ensure an optimal operating temperature in all conditions. It includes a low-temperature system that contributes to cooling the intercooler and a high-temperature system that cools the engine block and the two turbochargers.
Meanwhile, the oil supply system has also been designed to meet the challenges of dynamic track driving. The engine's weight-minimised oil sump has two separate chambers and an integrated suction channel, while the additional suction stage allows the map-controlled oil pump to draw lubricant from the smaller chamber when extra capacity is needed.
