BMW 6 Series Gran Turismo review

BMW excepts to shift just 1,500 of these a year in the UK, which is slightly better than the best year for the old 5GT. Not a car you saw very often. So the 6GT should stay relatively rare and they're not forcing the market too much. With luck, that'll keep the residuals up and hence leasing rates down.

Also, it's got a lot of standard kit. Professional navigation, LED headlights, metallic paint, 20Gb hard drive, all-round park sensors and a reversing camera. It seems mean of BMW to ask £235 for CarPlay. but pretty much all the Apple functions are replicated by the native BMW systems, so you can probably manage without.

Leather is standard but the fancily stitched soft stuff in the photos is £775, and the gotcha is BMW lets you order it only if you also have the super-adjustable front seats, another £1,705.

Other big options include the excellent and comprehensive head-up display at £995. The stereo comes in four steps, the standard one, then levels branded BMW, Harman Kardon or Bowers & Wilkins.

For company car users, the 6GT models sit in tax bands between 26 per cent (630d) and 36 per cent (640i xDrive M Sport). That gap shows why the diesel will be the most popular, though 28 per cent for the 630i looks good given it has a lower retail price than the diesel. Interestingly, if you equip the diesel with optional xDrive, its CO2 rises above that of the RWD 630i petrol.
