The Top Gear car review:BMW 6 Series Convertible
What is it like on the road?
As part of a master plan to banish the confused legacy of the last 6 Series, BMW released this one as a convertible first. Ignoring, for a moment, the ludicrously rapid M6, there are three engines on offer. The best, we reckon, is the six-cylinder 313bhp diesel found elsewhere in BMW’s line-up (640d). If you absolutely must have a petrol, the choice is between a 320bhp straight-six (640i), or a 449bhp V8 (650i). There’s not a massive amount between them on paper (4.6 seconds to 62mph plays 5.4) but the bigger one has a colossal 479lb ft, making it perfect for overtaking peasants when you’re late for the Masonic lodge disco. Mind, the lighter front end and hi-revving nature of the 640i makes it that bit more fun - though neither version is exactly nimble.
Adaptive chassis settings and all, this is a big car with light steering, a buttery smooth auto ‘box, elastic damping and an emphasis on quiet – roof up or down.
