BMW 6 Series fuel economy (UK)
Official figures for the BMW 6 Series from the Vehicle Certification Agency's new car lists, 2004–2018: 153 versions after removing repeats between lists. Economy is in UK (imperial) mpg; electric versions show miles per kWh and range instead. In the most recent lists (2005–2018, NEDC) combined economy is 18.6–57.6 mpg.
All figures on this page come from the NEDC test. NEDC was the official test before WLTP. NEDC figures are noticeably more optimistic, so do not compare them with WLTP figures.

Using these figures
"In lists" shows which yearly VCA lists include the version; it is not the model year. Manufacturers supply figures to the VCA voluntarily, so some makes are missing from some years' lists (for example several large brands between 2019 and 2024); a gap in the years does not mean the car was not sold. Click an mpg figure to open the trip fuel cost calculator with it in UK units, or convert it with the fuel economy converter. Real-world economy is usually lower than official figures — measure yours with the MPG calculator.
