This may look like the 3 Series coupe, but look again. BMW unveiled its successor at the 2013 North American International Auto Show in Detroit, and the magic number is now 4. The Concept 4 Series Coupe is a bit longer, wider and lower than its 3 Series predecessor and has an overall sleeker look.
Outside, it wears full LED headlamps and an exterior accented with satin-finish aluminum, including air intakes, door handles and side mirrors. Check out more photos below.
