BMW unveiled today the 2013 4 Series Coupe Concept, the replacement for its old 3 Series Coupe. Renamed with the mark 4, the car is set to be unveiled at this year Detroit Motor Show, anticipating the street version of the car no later than march 2013 in Geneva Motor Show.
The new 2013 BMW 4 Series Coupe will mark the begining of a new era: the one of the fourth generation of its sporty mid-range coupe.
BMW has given the new model its own individual character and a standalone design. The “4” stands for greater sportiness, greater exclusivity and even clearer differentiation from the BMW 3 Series range.
The new 4 Series Coupe has grown in size. The wheelbase (2,810 mm) is 50 millimetres longer than that of the existing 3 Series Coupe, while 45 mm has been added to the front track (1,545 mm) and 80 mm to the rear track (1,593 mm). At 1,826 mm wide, the BMW Concept 4 Series Coupe is 44 mm broader than its predecessor, its roof line is 16 mm lower (1,362 mm) and it is also longer (4,641 mm).
On the outside, the concept uses a kidney grille that is closed off in the interests of optimising aerodynamics and keeping fuel consumption low. The areas between the elaborately designed, satin-finish grille slats are blanked off by dark surfaces.
The full-LED headlights are hexagonal and adopt the link between the lights and kidney grille familiar from the BMW 3 Series, taking them it to the next level, rendering this connection visible in darkness as well.
