The launch of the new BMW M3 Saloon and new BMW M4 Coupé heralds the arrival of the fifth-generation of the iconic high-performance sports car from BMW M. For the first time the Coupé and Saloon models receive individual model names, in deference to the different model series that provide their basis.
Another first is the adoption of a turbocharged engine for this BMW M model: the high-revving, 3.0-litre six-cylinder in-line engine with M TwinPower Turbo technology has been specifically developed for this purpose, and produces a maximum output of 431hp. Its peak torque of 550Nm is available across a very wide rev range starting at just 1,850rpm, and exceeds the figure recorded by the outgoing BMW M3 by roughly 40 per cent. In spite of this, the new engine also achieves a reduction in fuel consumption and emissions of around 25 per cent.
To maximise dynamic ability and ensure excellent efficiency, a weight loss of over 80kgs has been achieved compared to a comparably equipped predecessor model. Specific weight-saving measures include the increased use of lightweight materials: both models now feature a carbon-fibre reinforced plastic roof.
BMW M engineers have paid particular attention to the car’s aerodynamic performance, and incorporated the latest Active M Differential amongst numerous other technical highlights. During the development process the engineers worked closely with BMW Motorsport’s professional racing drivers, with extensive testing and set-up work carried out on the Nürburgring Nordschleife circuit.
