DETROIT LIVE: BMW’s Concept 4 Series Coupe previews production model

BMW is showing its 4 Series Coupe concept car in flesh and bone for the first time at the Detroit Motor Show.

Although the automaker calls it a concept car, the production model will look almost identical when it goes on sale at the end of this year. The car will replace the 3 Series Coupe in BMW’s lineup, with all coupes and convertibles to wear even numbers from now on (2 Series, 4 Series, 6 Series). Hopefully the production model will retain as much as possible from this concept.

The BMW Concept 4 Series Coupe has a wheelbase (2,810 mm) that 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). All this translates into dynamic proportions that please the eye.

Technical details are yet to be announced, but the car is likely to offer the same engines from the 3 Series sedan. Expect a 2.0-liter turbocharged four-cylinder and a 3.0-liter turbocharged six-cylinder that may wear the 428i and 435i/440i designations.
