Earlier this month, BMW revealed the 2008 M3 Concept at the Geneva Motor Show. At the time, the automaker only said the production coupe would feature a high-revving V8. The company has since released full details on the production motor, which is more powerful and lighter than the old M3′s straight-six.
- First eight-cylinder for the BMW M3 .
- 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. - 340 Newton-metres or 251 lb-ft available from just 2,000 rpm.
- 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.
- Exhaust system optimizing cylinder charge, optimized 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.
