The wraps have finally come off the second-generation BMW 4 series Convertible. It’s available to buy now, priced from £45,785 – and, when the first examples hit the UK next March, it’ll offer fresh competition for the Mercedes C-Class Cabriolet and Audi A5 Cabriolet.
The 4 series Convertible’s styling is pretty much similar to the Coupe’s – save for a new chrome fit together radiator grille and the missing roof. However, for this second-generation model, BMW has tried something different, dropping the old car’s folding metal hardtop for a new fabric roof.

BMW says the new roof is 40 per cent lighter than the outgoing model’s tin-top – and that there’s bit appreciable difference in the amount of acoustic or thermal insulation. The roof can also be operated at speeds of as much as 31mph, taking 18 seconds to open or close.

The company’s engineers have also tried to retain as much of the coupe’s structural rigidness as possible, adding a bracing shear panel for the front end and stronger side skirts. BMW says that its efforts have made the new 4 series Convertible around four per cent more stiff than the old model.

Unlike the 4 series Coupe, the Convertible comes as conventional in BMW’s M sport specification, which includes 18-inch alloy wheels, uprated suspension, LED headlights and a more aggressive M-Sport bodykit. The same theme continues inside with an M-Sport steering wheel and a pair of leather-trimmed, M-badged sport seats.
