BMW 6-Series Convertible

BMWs top of the line convertible is a fine piece of engineering offering exceptional handling, elegant looks and a fine interior. The previous BMW 6-Series Convertible was an excellent car, but wasn’t as handsome as competitors from Porsche and Mercedes. The 2011 released car cleaned up its act on this count as well as making general improvements all round.

  1. Dave Dave says:

    I’ve had my 640d m sport for a year now, 51mpg is only achieved in Eco mode 36 mpg is a far more realistic figure! The m sport has the body kit, sport steering wheel and M entry plates, the roof is faultless’!
    0-60 in 5.5 from a diesel is awesome, and has a nice little roar when booted…. you won’t believe it’s a diesel engine only at first start Up.
    There have been no faults whatsoever, I tend to drive it in sport mode as this sharpens up the throttle response considerably there are 4 modes to play with comfort, sport, sport+, eco mode, it’s a big car and needs concentration while parking or you will bash the 20 inch M alloys.
    Plenty of room in the back even for long journeys (which is rare for a cabrio, a lot boast 4 seats but don’t deliver in reality) the boot is a decent size, again a rarity in a convertible.
    In summary a very accomplished vehicle and I would award it 9 out of 10. Don’t pay full price as BMW will do deals.
