The new BMW M3 Saloon and 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 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.
The balance of the overall concept: high power, low weight, driving pleasure.
The new BMW M3 Saloon and new BMW M4 Coupe are formed from a host of finely blended elements, all working in perfect harmony to deliver outstanding performance, precision and agility on road and track.
With the new BMW M3 Saloon and M4 Coupe, the engineers sought to optimally channel the air around the car in the quest for ultimate performance, while also ensuring the engine, powertrain and brakes receive the requisite cooling. Even when operating under heavy loads on the racing circuit. The aggressively styled front apron, smooth under-body and the clearly defined lip spoiler at the rear of the M3 Saloon (or integrated bootlid spoiler at the rear of the BMW M4 Coupe) reduce lift by an equal amount at the front and rear axle, to the benefit of handling.
Albert Biermann, Head of Development at BMW M GmbH, said: “The way in which we channel the inflowing air through the engine oil cooler creates a venturi effect, which reduces front axle lift and, in so doing, improves the steering.”
The Aero Curtain and M side gills, the latter with integrated Air Breathers minimise turbulence in the front wheel arches. These elements, together with the aerodynamically optimised side mirrors in familiar M twin-stalk style, are not only distinctive design features, they also help to reduce drag.
The new six-cylinder in-line engine: high-revving, turbocharged unit combines the best of both worlds.
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-generations of this iconic sports car.
