The new BMW M3 Sedan and new BMW M4 Coupe from BMW M GmbH see a return to a six-in-line engine configuration, as used on the second and third generations of this iconic sports car. The new turbocharged engine combines the best of both worlds -- reaching a maximum 7,600 rpm, it is unusually high-revving for a turbocharged engine, resulting in linear power delivery over a wide engine speed range and a characterful engine note, while M TwinPower Turbo technology ensures that peak torque is on top over a broad rpm range. A further hallmark of this engine is its outstanding efficiency.
The new engine sees a slight power upgrade over the previous V8 to 431 hp, which is delivered between 5,390 and 7,000 rpm. Peak torque has been increased by roughly 40 per cent to 550 Newton metres, and is maintained over a very wide rev band (1,800--5,390 rpm). The standard sprint from zero to 100 km/h (62 mph) takes the new BMW M3 Sedan and new BMW M4 Coupe 4.1 seconds respectively. Top speed is 250 km/h / 155 mph (electronically limited), or 280 km/h / 174 mph if the optional M Driver's Package is specified. The new powerplant also boasts excellent fuel economy: the BMW M3 Sedan and BMW M4 Coupe achieve consumption in the EU cycle of 8.3 l/100 km (34 mpg) and CO2 emissions of 194 g/km, an improvement of more than
25 per cent over the previous model's figures.
