Today, BMW steps into a new segment where the differentiation between similar vehicles are made at the numbering level. Following Audi’s steps, BMW splits the 3 Series family into separate offerings: the 3 Series Sedan and sports wagon remains under the old nomenclature, while the coupe and convertible variants get a new name – 4 Series.

The BMW Concept 4 Series Coupe adds a new dimension to the qualities of the BMW 3 Series Coupe in terms of aesthetics, dynamics and elegance.

The latest addition to a nomenclature that sees BMW building on the fine tradition of its large BMW 6 Series and BMW 8 Series Coupes, the “4” stands for greater sportiness, greater exclusivity and even clearer differentiation from the BMW 3 Series range.

In the photo comparison below, the 4 Series takes on the aforementioned Audi A5 and the Mercedes-Benz E-Class Coupe.

The Audi A5 starts at $37,850 with a 211 hp 2.0 turbo TFSI motor and quattro all-wheel drive but can be
optioned all the way to a RS5 450-horsepower version that has a 0-60 mph of 4.5 sec and a top speed of 174 mph. The RS5 starts a $69,975 and is targeted at BMW’s M version of the 4 Series, M4, that will come to market in 2014.

The C-Class Coupes – the C250, C350, and C63 AMG Coupe has an MSRP which ranges from $37,800 for the C250 Coupe that comes with a 1.8L turbo charged 4 cylinder with 201 horsepower, all the way to a MSRP of $62,330 for a normally aspirated 6.3L AMG V8 that produces 451 hp, 443 lb-ft of Torque.

Visually all these competing models have a certain appeal that can and are catering to a wide range of customers, some may enjoy the sportiness and dynamics of the 4 Series (just in concept form for now) or the fluid lines and interior luxury of the A5 and the classic design of the C-Class Coupe.
