2014 Detroit Auto Show Live: BMW M3 Sedan image

After it was officially unveiled along with its M$ Coupe sibling, the hot M3 Sedan was publicly unveiled at the 2014 North American International Auto Show.

As usual, besides the fact they look great, the M3 versions bring a powerful “heart” – for the 2014 M3 in the form an inline-six high-revving TwinPower Turbo 3.0-liter engine churning 431 HP (317 kW) and a maximum torque of 406 lb-ft (550 Nm).

“The superior performance of the BMW M3 Saloon and BMW M4 Coupé should be obvious at first glance,” explains Karim Habib, Head of Design at BMW Automobiles. “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.”

We also have a standard CFRP roof, that brings weight savings of 5 kg (11 lbs) for the sedan and more than 6 kg (13 lbs) for the coupe. BMW says the cars will do 26.7 mpg US (32.1 mpg UK or 8.8 liters / 100 km) in the combined cycle with the manual and 28.3 mpg US (34 mpg UK or 8.3 liters / 100 km) with the DCT. Compared to the outgoing generation, the new M3 is approximately 25 % more fuel-efficient and is around 80 kg (176 lbs) lighter.

Just like its coupe sibling, the M3 sedan will do 0-62 mph (0-100 km/h) in 4.1 seconds when fitted the optional 7-speed M DCT or 4.3s with the standard six-speed manual gearbox. Top speed is the usual electronically limited 155 mph (250 km/h), but if the client orders the M Driver’s Package, the limiter can be raised at 174 mph (280 km/h).

As an interesting fact, besides being blazing fast, the seven-speed M DCT comes with launch control and a “smokey burnout” mode that allows a certain degree of wheel spin at low speeds, while stopping will be dealt via the standard compound brakes or optional lighter BMW M carbon ceramic brakes.
