At the beginning of next year, BMW fans will have to get used to calling the new coupe version of the 3-Series the 4-Series as BMW previewed the production model through a very thinly disguised concept at the North American International Auto Show in Detroit.
In comparison to the current 3-Series that is out, the 4-Series concept features a slightly longer wheelbase, wider stance, and considerably lower roofline. Along with getting rid of the full leather interior trims, the exterior mirrors, bumper designs, and large alloy wheels will be toned down a bit on the concept when it is put into production.
Although this car shows a different name on the front, the 4-Series will borrow its entire lineup from the 3-Series sedan, with offerings in the U.S. to include the 428i with a 240hp 2.0 liter turbocharged gasoline unit and the 435i with a 300hp 3.0 liter twin-turbo inline six. Europeans will get a more extensive engine lineup that will include diesel options. Later in 2014, a hotter M4 variant with a turbocharged six delivering around 450 hp will follow the 4-Series.
