MPG and running costs
Running a twin-turbo 4.4-litre V8 is never going to be cheap, but BMW claims a reasonable 28.5mpg on the combined cycle. On a motorway run that could just creep into the 30s, but the moment you stretch the car over an inviting stretch of road it could equally drop into the low teens.
An 80-litre fuel tank means real world range now tops 400 miles at a gentle cruise, which is a significant improvement over the previous model.

Running costs mount up when it comes to consumables. Tyres come in the form of Michelin Pilot Super Sports, which are 265/35 at the front and 295/30 at the rear – expect to pay the best part of £1000 for a full set. The car is also in road tax band L, which means £485 a year thanks to its 231g/km of CO2.
