A prototype of the 2014 BMW M3 Sedan (F80) was seen on German roads wearing a Mineral White exterior paint scheme.

It was only yesterday when an M4 Coupe was spotted on Audi's turf in Ingolstadt and now its M3 four-door sedan sibling was immortalized on German roads with an attractive Mineral White paintjob and a red leather interior cabin.

BMW developed a new 3.0-liter inline-six engine outputting 431 HP (317 kW) and 406 lb-ft (550 Nm) of torque working with either a standard 6-speed manual or an optional 7-speed M DCT. With the latter, the M3 Sedan does 0-62 mph (0-100 km/h) in 4.1 seconds and a top speed of 155 mph (250 km/h) or 174 mph (280 km/h) when configured with the M Driver's Package.

For more money customers will be able to equip their M3 Sedan with an optional carbon fiber roof that will shed 5 kg (11 lbs) from the car's weight and it will also lower its center of gravity.

The all-new M3 and M4 will be showcased in January at the North American International Auto Show (NAIAS) in Detroit.
