MPG and running costs
The M3 has never been a cheap car to run, and the new one is no different. BMW claims the M3 can achieve 34mpg, but in reality that will plummet to mid- to low-20s if you tap into the car’s true performance.
With such significant power and torque, the M3 is going to go through rear tyres relatively quickly. The 275/35 19 Michelin Pilot Super Sport tyres, that are standard fitment for the M3, cost around £220 each. The Competition Pack comes on bigger 20-inch wheels with larger versions of the same tyre; it runs 285/30 20 rear tyres. Thankfully the bigger, wider tyres aren’t much more expensive at £230 each.

Front tyres for the M3 are cheaper, at about £177 for the regular car and £220 for the Competition pack, but won’t have to endure quite as much pain and probably won’t need changing as frequently as the rears.
As with many high performance cars the M3 has a running-in period of 1200 miles, at which point it needs to be serviced. This is also when the car’s launch control is activated.
