new BMW M4 Coupe

The launch of the new BMW M3 Saloon and new BMW M4 Coupe heralds the arrival of the fifth-generation of the iconic high-performance sports car from BMW M. For the first time the Coupe 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 maximize 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.

The new BMW M3 Saloon and new BMW M4 Coupe mark a return to the classic six-cylinder in-line engine configuration, as used on the second and third-generatios of this iconic sports car. The new engine sees a slight power upgrade over the previous V8 to 431hp, now delivered between 5,500 and 7,300rpm, with maximum revolutions set at an unusually high figure for a turbocharged engine: 7,600rpm. Peak torque has been increased by roughly 40 per cent to 550Nm, and is maintained over a very wide rev range (1,850–5,500rpm). The standard sprint from 0-62mph takes both cars just 4.3 seconds with manual transmission, or just 4.1 seconds with the optional M DCT, while the top speed is 155mph (electronically limited). The new powerplant also boasts excellent fuel economy: the combined consumption in the EU cycle is as high as 34mpg and CO2 emissions are as low as 194g/km, an improvement of more than 25 per cent over the previous model’s figures. Regulated pollutant emissions are EU6-compliant.

The M Twin Power Turbo technology comprises two fast-responding mono- scroll turbochargers, High-precision direct injection, VALVETRONIC variable valve timing and Double-VANOS continuously variable camshaft timing. VALVETRONIC and Double-VANOS work in tandem to seamlessly control intake valve lift. The result is a smooth and efficient power delivery, with very sharp response and reduced fuel consumption and emissions.
