As of spring 2010, the high-performance model BMW M3 consistently combines its outstanding driving performance figures with further reduced fuel consumption and exhaust emission levels. The range of BMW EfficientDynamics measures fitted as standard in the models BMW M3 Coupé, BMW M3 Convertible and BMW M3 Sedan is now to be supplemented with the Auto Start Stop Function. This reduces the average fuel consumption and CO2 levels of the BMW M3 by up to 8 per cent or 24 grams of CO2 per kilometre.
The BMW M3 achieves its outstanding performance with impressive efficiency. Its 4.0 litre V8 high-revving engine mobilises 309 kW/420 bhp, enabling superior acceleration response due to its unique propulsion. In addition to its fascinating performance characteristics, the 8-cylinder engine - developed exclusively for the BMW M3 - is characterised by an unusually high degree of efficiency.
