BMW M5 (G90) – MPG and running costs

Don’t expect anything like the claimed 177mpg on longer trips. Shorter journeys can be completed purely on electric power

  • Still does everything you’d expect of an M5
  • Plus some stuff you don’t

One of the major benefits of the M5’s PHEV switch is that it should be cheaper to run. That is, if you regularly keep the battery topped up to make use of the electric power on offer, rather than just using the engine to lug the heavy hybrid componentry around for comparatively little benefit.

BMW claims the M5 achieves 176mpg on the WLTP testing cycle, but real-world economy will depend largely on how you use it. Short trips that make use of its 42-mile electric range will of course be more cost-effective than an equivalent pure-petrol supersaloon, but drive longer distances, use more of its potential and that gap will close. BMW quotes 28mpg on the WLTP cycle with an empty battery. 

In terms of consumables, the M5’s epic performance and weight will surely take a toll on the brakes and tyres. Direct replacements for M5’s Michelins aren’t available yet, but expect a full set to cost somewhere around £1500.
