Converts power into amazement: The M TwinPower Turbo 8-cylinder petrol engine is the crowning glory of the M power units. Its enormous power of 423 kW and 680 Nm is available at all times thanks to the innovative TwinScroll turbocharging concept and is further increased to staggering 442kW and 700 Nm with the optional Competition package.
This is possible due to the combination of high engine speeds, turbocharging and technological highlights such as Valvetronic and High Precision Injection. And full torque goes on stream from approx. 1,500 rpm, charting an impressive output curve of virtually linear power delivery −as well as putting a smile on the driver's face. The M TwinPower Turbo 8-cylinder petrol engine demonstrates that power and efficiency are by no means mutually exclusive with its intelligent BMW EfficientDynamics technologies such as Brake Energy Regeneration. These make for an average fuel consumption of just 9.9 litres of petrol per 100 kilometres.
