BMW officially introduced today the new M3 Sedan and M4 Coupe. As expected, the vehicles are powered by a new 3.0-liter high-revving six-cylinder in-line engine with M TwinPower Turbo technology that produces a maximum output of 431 hp and 550 Nm (406 lb-ft) of torque.
This means that the new six-cylinder engine delivers more power than the previous V8 found on the previous M3. With the new engine, the BMW M3 Sedan and the M4 Coupe sprint from 0 to 100 km/h (62 mph) in 4.1 seconds, while the top speed is electronically limited at 250 km/h (155 mph). Still, for those who want more, there is the optional M Driver’s Package, that raises the top speed at 280 km/h or 174 mph.
Despite these impressive numbers, fuel consumption in the EU cycle remains low: 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.
Regulated pollutant emissions are EU6-compliant. On the outgoing model, the CFRP roof was offered only on the Coupe version, but now, for the first time, the four-door BMW M3 Sedan gets this functional feature as well. On the sedan, the CFRP brings weight savings of five kilograms and more than six kilograms on the M4 Coupe. Made from aluminium rather than conventional steel, the front side walls and the bonnet (with power dome) make an important contribution to the models’ lightweight design concept, while at the same time improving axle load distribution.
Viewed from the front, both the M3 Sedan and M4 Coupe show their powerful contours and a strongly defined three-dimensionality. At the rear, the M3 Sedan comes with a Gurney spoiler to reduce lift, while the M4 Coupe features an integrated spoiler made from lightweight carbon-fibre-reinforced plastic.
Inside, we find the traditional BMW M equipment such as M door sill finishers, an M driver’s footrest, M gearshift lever, M-design circular instruments with white graphics, M leather steering wheel with chrome trim, colour contrast stitching and electroplated- look shift paddles (if the M DCT gearbox is specified).
The most important features of the vehicles is the Smokey Burnout function that allows the driver to indulge in a degree of rear wheel spin while the car is moving at low speeds. Stability Clutch Control opens the clutch when the car is understeering to bring it back into line.
