BMW’s future 4-series line-up will include a coupe and a convertible version, as well as their M4 variants, but the lineup still isn’t complete. BMW is planning on bringing out a competitor for models like the Audi A5 Sportback and the upcoming Mercedes CLA. Their solution? A 4?series Gran Coupe that will follow in the path of the recently released 6-series GranCoupe. The BMW 4-series Gran Coupe will be based on the upcoming 4-series Coupe, but will get two more doors, a slightly longer wheelbase, and a set of usable rear seats. Its exterior design will be similar to the one found in the 3-series, but will add gaping air intakes and smooth aluminum style inserts for a more upmarket feel.
Under the hood, BMW will be placing the same engines found in the coupe version. This means there will be a choice of four engines – two petrol and two diesel – with the most powerful version being the 435i with an output of 306 HP. BMW will also be offering an M4 Gran Coupe model that will be powered by a 450 HP six-cylinder turbo engine.
