BMW M5 Competition F90 review – ​MPG and running costs

With great power comes great fuel consumption – it’s thirsty, while the complex power and drivetrains bely its familiar shape

Evo rating
RRP
from £111,425
  • Powertrain devastatingly effective; more dynamically capable than rivals and beautifully built
  • It’s big; steering lacks life; soundtrack is too augmented

Hot-V V8 engines have a reputation of quite astonishing fuel consumption when being worked and BMW’s is no different.

The near-two-ton kerb weight has other compromises such as an appetite for tyres, brake pads and suspension components. BMW’s standard-fit Michelin Pilot 4 S tyres aren’t as aggressive as some, but the 275- and 285-section front and rear tyres to fit the Competition’s standard 20-inch wheels will cost around £1200 a set to replace.
