Description in brief:

• First eight-cylinder for the BMW M3 sports car.
• Supreme performance ensured by 309 kW/420 hp from 4.0 litres.
• Maximum torque of 400 Newton-metres (295 lb-ft) at 3, 900 rpm,
85 per cent of maximum torque over a speed range of 6,500 rpm.
• Unique thrust and muscle ensured by consistent implementation of the M
high-speed engine concept, maximum engine speed 8,300 rpm.
• Consistent lightweight construction of engine and ancillary units,
new V8 power unit one of the lightest eight-cylinders in the world,
lighter than the straight-six power unit in the former model.
• Variable camshaft control, low-pressure double-VANOS for an
optimum charge cycle, system offering full power and performance even with
normal engine oil pressure.
• Eight individual throttle butterflies for spontaneous engine response.
• Consistent and reliable oil supply with longitudinal and lateral
acceleration up to 1.4 g ensured by two oil pumps and wet sump oil lubrication
optimised for supreme dynamic behaviour.
• Exhaust system optimising cylinder charge, optimised for weight and
function by means of internal high-pressure remoulding, exhaust emissions
fulfil EU4 and LEV 2 standards.
• Upgraded MSS60 engine control unit for optimum coordination of all engine
functions with the various control systems in the car.
• Ion flow technology recognising and distinguishing engine knocking
phenomena as well as misfiring and miscombustion by measurement of ion flow in
the combustion chambers.
• Brake Energy Regeneration with intelligent alternator control.
