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.
Both dripping with tech, for the first time the Coupé and Saloon models receive individual model names.
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.
With new engine seeing a slight power upgrade over the previous V8, 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.
To maximise dynamic ability and ensure excellent efficiency, a weight loss of over 80kgs has been achieved - 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 new BMW M3 Saloon and new BMW M4 Coupé 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 Coupé, 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 Coupé) reduce lift by an equal amount at the front and rear axle, to the benefit of handling.
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 cars launched on June 21st and are priced at £56,175 OTR for the M3 Saloon and £56,635 OTR for the M4 Coupé. BMW UK expects to sell 1,000 BMW M4 Coupés and 180 M3 Saloons in their first full year of sales.
