What is it?
BMW has made it tradition to introduce coupe versions of new models prior to its cabriolet siblings, the time gap between the two usually running to around six months depending on production capacity. The new 6-series curiously dispenses with this habit.
It’s a smart move, providing the new 6-series with a distinct kick start to sales. Not that BMW is relying solely on seasonal weather to generate showroom traffic. It’s also given its new open top a heady dash of style as part of a complete re-engineering job that sees it adopt a new rear-wheel drive platform, more contemporary engines created under BMW’s EfficientDynamics banner and a whole host of electronic chassis components included in the company’s recent Dynamic Drive initiative.
What’s it like?
Gone is the bullish and bloated look of the old model, replaced by a much more elegant and cohesive lineage. Not surprisingly, given it is based on the same underpinnings as the latest generation 5-series, the new 6-series cabriolet has grown in length and width, putting on 74mm and 39mm respectively, although height is down by a scant 8mm – all of which serves to give it a longer and more lithe profile together with a more confident and athletic stance.
As with the exterior, the interior has also been thoroughly reworked, with a unique dashboard and centre console – the latter now angled slightly towards the driver for a more cosseting feel than that of the old 6-series cabriolet. The perception of quality has also received a welcome lift thanks to the inclusion of higher grade materials and added attention to detail.
The increased dimensions provide front seat occupants with plenty of accommodation, although entry is impeded somewhat by the heavily raked nature of the windscreen despite the generous length of the doors, which like the bonnet are fashioned from aluminium in a bid to trim weight. The individual rear seats, like those up front, are generous in size but, for a car measuring almost five metres in length, lack for any real legroom and are not at all easy to climb into with the roof up.
As with the first-generation 6-series cabriolet launched in 2004, this new one uses a fabric hood that can be operated at speeds up to 40km/h. The vertical rear window, which can be automatically lowered into the rear bulk head via a switch on the driver’s door, is brought over from the old model.
When the new 6-series cabriolet reaches the UK in March, buyers will get to choose between two petrol engine options. They include a turbocharged 3.0-litre in-line six-cylinder with 316bhp and 332lb ft of torque in the 640i as well as a twin-turbocharged 4.4-litre V8 packing 401bhp and strapping 442lb ft in the 650i driven here.
Although it weighs a good deal more than the in-line six-cylinder the V8 delivers truly heady levels of performance along with extraordinary levels of refinement.
Despite lacking the automatic stop/start system that will be standard on the 640i cabriolet here in the UK, BMW claims the new 650i cabriolet’s engine records a slight two per cent reduction in fuel consumption over the naturally aspirated 5.0-litre V8 it replaces in the 650i cabriolet at a combined 26.4mpg.
