Eight-cylinder high-rev engine.

The eight-cylinder high-rev engine is a perfect example of the high engine speed concept that is key to the thrilling performance of BMW M automobiles. It is featured in the BMW M3 Coupé, and produces up to 309 kW (420 hp) from an engine displacement of 3,999 ccm. Its top torque of 400 Nm is reached at 3,900 rpm, and even above engine speeds of 6,500 rpm, 85% of its maximum torque is constantly available.

The high-rev concept is technologically extremely demanding, with engine speeds reaching 8,300 rpm, but it enables supremely sporting and more reliable responsiveness, better performance and greater efficiency than engines with turbo-charging or with larger displacement. The V8 high-rev naturally-aspirated engine merges motorsports technology with everyday driving usability.
Consistent application of lightweight construction technology and eight electronically-controlled individual throttle valves enable the V8 powerplant to produce thrilling performance. Proven on the racetrack, the use of individual throttle valves is a characteristic of all BMW M engines. They achieve greater responsiveness at low engine speeds and enhanced spontaneous power output.
A further design highlight of the V8 M engine is its oil pump technology, which delivers full functionality even at lateral and transverse g-forces of up to 1.4 g. The innovative ionic-current anti-knock system monitors every combustion process, recognising and counteracting any signs of engine knock or misfiring. A boost to fuel efficiency is achieved by Brake Energy Regeneration, which uses intelligent alternator management to recharge the car's battery by converting the engine's energy to electricity during coasting or braking.
