BMW is expected to introduce a concept version of the next-generation 3 Series Coupe at the North American International Auto Show (NAIAS) in Detroit in January, and with it a new name.
With the BMW Concept 4 Series Coupe, the company says it is looking ahead to the fourth generation of its sporty mid-range coupe, which will bear the same designation. So will a convertible body-style, expected to follow later next year.
The "4" marks the start of a new cycle, BMW says. It has given the new model its own individual character and a standalone design, with greater sportiness, greater exclusivity and even clearer differentiation from the BMW 3 Series range.
It's the same pattern Audi followed with its A5 coupe and convertible, elevating them above the A4 – in both status and price. Presumably, BMW will take advantage of the 4 Series' differentiation to achieve the same ends.
Dimensionally, the Concept 4 Series Coupe's 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, it 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 of which is said to enhance its dynamic proportions.
It's a familiar BMW template: long wheelbase, long hood, set-back passenger compartment and short overhangs, with the surfaces stretched taut. The profile is both sporty and elegant.
Functional elements such as air intakes and vents, door openers and exterior mirrors are highlighted with satin-finish aluminum on the Concept.
