BMW has abandoned its traditional launch approach with the third-generation 6-series by introducing the soft-top version of the new two-door before the successor to the fixed-head coupé.
Pictured here at its public premiere at today's Detroit motor show, the upmarket convertible is planned to go on sale in the UK in March, six months before the new 6-series coupé is set to reach local BMW showrooms.
The new convertible is a clear evolution of the outgoing model. It carries fresh new styling first revealed on the four-door BMW GranCoupé back in April, plus increased exterior dimensions and a roomier four-seat interior.
It also gets an advanced new multi-layer cloth hood, developed in partnership with German-based roofing specialist Edscha.
The fully automatic structure, which retains the characteristic buttresses that extend back over the bootlid, is claimed to open in just 19sec and close in 24sec.
It is covered by a plastic tonneau cover when lowered to preserve the car’s elegant new lines. The glass rear screen, mounted vertically, can be opened independently of the cloth hood.
At 4894mm in length, 1894mm in width and 1365mm in height, the new convertible is 74mm longer, 39mm wider and 9mm lower than its predecessor. It also rides on a wheelbase that has been extended by 74mm at 2855mm.
Inside, there’s a more driver-orientated dashboard and centre console than in the old model, and greater leg, head and shoulder room. Luggage capacity remains the same as before, at a nominal 350 litres when the roof is up and 300 litres in open-top guise.
