BMW unveiled today the brand new 2014 M3 Sedan and M4 Coupe, ahead of their public debut scheduled for the 2014 Detroit Motor Show. Under the bonnet of the fifth generation M3 is the brand new inline six TwinPower Turbo 3.0 liter engine. The unit can deliver 431 horsepower and 550 Nm peak of torque which is available across a very wide rev range starting at just 1.850 rpm.
Compared to the old generation, the new German performance sedan is 25% more fuel efficient and approximately 90 kg lighter. According to German officials, the 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.
Under these conditions, the BMW M3 Sedan and M4 Coupe can sprint from stand still to 100 km/h in 4.1 seconds, while the top speed is clocked at 250 km/h (280 km/h when equipped with M Driver Package). According to BMW, both cars can offer a combined fuel consumption of 31.1 mpg with 194 grams of CO2 per kilometer.
The standard transmission specified is a six-speed manual gearbox with a robust double-plate clutch. This unit is considerably more compact than its predecessor and also 12kgs lighter. The optional transmission for the new BMW M3 Saloon and M4 Coupé is the third-generation M Double Clutch Transmission (M DCT). As well as changing gear automatically, in manual mode it enables ultra-fast gear changes with no interruption in the flow of power.
“The impressive stiffness and low weight of the CFRP tubing allow the driveshaft to be constructed as a single-piece unit with no centre bearing. As well as a weight-saving of 40 per cent over its predecessor, we have achieved a reduction in rotating masses and therefore improved drivetrain dynamics”, explains Albert Biermann.
The 2014 BMW M3 Sedan and M4 Coupe are featuring a more aggressive and sporty design. The expressive face is dominated by the double-slat kidney grille and by the twin headlights.
The front apron is featuring larger intakes, while the bonnet is completing the unique styling. The dark color of the CFRP roof (with its contoured roofline) gives both models a lower-slung and more compact appearance. At the rear, there are greater differences in the two models. The BMW M3 Saloon is fitted with a lip spoiler to reduce lift, while the tailgate of the BMW M4 Coupe features an integrated rear spoiler and is made from a carbon-fiber compound.
“The superior performance of the BMW M3 Saloon and BMW M4 Coupé should be obvious at first glance. Indeed, the exterior design has a visual impact that elevates the BMW M design language to a new level of expression, highlighted by a purposeful character, emotional appeal and dynamic verve”, explains Karim Habib, Head of Design at BMW Automobiles.
