Hot-V V8 engines have a reputation of quite astonishing fuel consumption when being worked and BMW’s is no different. During our time with the non-Competition M5 on our Fast Fleet we usually averaged between 26 and 28mpg, but given enough space would easily drop into the teens when you put your foot down.
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 between £800 and £1200 a set to replace.
