Audi RS7 Sportback Performance review – MPG and running costs

While a 621bhp two ton superhatch is never going to be efficient, all of Audi’s little eco-minded details do add up to something that’s merely thirsty, rather than irritatingly so. Stay at a cruise, leave the drive-select mode in Auto and it’ll schlep up and down motorways and even potter around town while returning nearly 30mpg. Put your foot in it though and things change very quickly, diving down into the teens when you make full use of the loud pedal. 

Consumables are another matter, as the RS7 will not be an inexpensive car to run thanks to the big tyres, brakes and engine. If the near-£10,000 price of those ceramic brakes turns you off, at least you’ll theoretically not need to change them any time soon, however stick to the still huge steel discs and come change day it’s likely to be a painful bill. The 22-inch Continental SportContact 7 tyres will also take a beating thanks to the forces exerted on them.
