BMW 6-series GT review – a high-class 5-series or a cut price 7-series? - MPG and running costs

BMW’s 6-series GT offers space, luxury and refinement and in 630d form a decent drive, too

MPG and running costs

BMW’s latest generation of engines offer an excellent blend of power and economy when it comes to claimed figures although as with all manufacturers real-world MPG won’t match the showroom claims. The 630i GT is claimed to return 43.4mpg with emissions of 148g/km while the 640i xDrive comes in at 35.3mpg and 183g/km. Unsurprisingly it’s the diesel that should be the economy champion with 55.3mpg (49.5 for the xDrive) on the combined cycle with emissions of 135g/km (150 with four-wheel drive). 

Realistically we’d knock up to 10mpg off those figures, and the 640i in particular seemed to like a drink when using the performance whereas the 630d was a little more parsimonious while on test.

With a three-year unlimited mileage warranty and the option to lock in servicing costs with BMW’s fixed price plans ownership should be a painless experience while residuals should sit in between the 5- and 7-series.
