  • What Car? says: 4 star rating
  • Fuel economy: up to 50.4mpg
  • What is it? It's designed to let you cover big distances in style and luxury, and get you get a suntan along the way

Great

  • Luxurious furnishings and look-at-me styling
  • Faster than a British summer
  • A powerful cruiser with jaw-dropping acceleration

Gripes

  • Back seats are best for tiddlers
  • You'll have to pay extra for a wind deflector
  • Big petrol engines sound great but will cost a fortune to run
  • Drive

    More of a mighty cruiser than a sports car but none the worse for that, and we love the engine's ferocious growl

  • Inside

    Lots of seat adjustment and the sensible layout you'd expect in a BMW

  • Safety

    Enough electronic safety kit to soothe the most anxious traveller; security kit is good, too

  • Reliability

    BMW has a good record for reliability and the car looks and feels beautifully put together so we wouldn't fret

  • Space

    You and a pal are fine up front but the back seats are best for kids or tall items of luggage: the boot is a fair size but shallow

  • Standard and extras

    Plenty of goodies including heated electric leather seats and sat-nav, but surely the wind deflector shouldnt cost extra?

  • What's it like to drive?

    Theres a firm edge to the ride at town speeds, but it smoothes out when you go faster and is superb at a motorway cruise.
    The 6 Series Convertible also benefits from strong grip and tight body control in corners, although it's too big and heavy to feel like a sports car, even in the most driver-focused, M Sport spec.
    BMW offers a 3.0-litre diesel model (misleadingly badged 640d) that combines gutsy performance with around 50mpg. Alternatively, if you believe petrol power is a must in a convertible, theres a 3.0-litre turbo (the 640i) and a 4.4-litre twin-turbo (the 650i).
    The fabric hood is good at keeping out unwanted noise, but some other convertibles are better at protecting occupants from roof-down buffeting. Its also disappointing that a wind deflector costs extra given the high price of the 6 Series.

  • What's it like inside?

    The cabin is beautifully trimmed, and the dashboard has the same orderly layout as most other modern BMWs.
    Theres no shortage of space up front, but limited legroom means the back seats are best left for children. Adults can just about squeeze in, but for short journeys only.
    More positively, the boot is long and wide  if a little shallow  and every 6 Series comes with heated, electrically adjustable leather seats, climate control, satellite-navigation and automatic lights and wipers.

  • How reliable is it?

    The 6 Series was too new to be included in the most recent JD Power customer satisfaction survey, but BMW as a brand finished in the top half.
    Safety equipment is fairly comprehensive, with every 6 Series Convertible getting four airbags, a rollover protection system and stability control. You also two sets of ISOFIX mounting points in the rear and a front passenger airbag deactivation switch that lets you mount a rear-facing child seat beside you.

  • Should I buy one?

    Other luxury convertibles - such as the Jaguar XK - are more fun to drive, but the 6 Series is one of the best cruisers. As long as youre not hoping to fit lanky teenagers in the back on a regular basis, its worth considering.
