The BMW M6 Gran Coupe is an extreme high-performance four-door coupe and one of three models in the M6 range, alongside the two-door coupe and convertible. It offers a slightly more practical alternative to the two-door M6 Coupe without sacrificing the car’s massive performance and imposing looks.

Running costs

Predictably, BMW M6 Gran Coupe running costs are anything but cheap. The ultra-wide high-performance tyres will be costly to replace and given the car’s prodigious power and tail-happy balance you’re likely to get through a fair few sets of rear rubber.

It also sits in insurance group 50 and towards the top of the VED tax scale (see below).

Officially it will average 28.5mpg but you will get through fuel at a rather quicker rate than that if you begin to scratch the surface of its performance credentials.

Compared to the yowling V10 of the old 2005 BMW M6 it’s a great improvement, though – that averaged a claimed 19mpg.

Two optional service packages are available - BMW Service Inclusive, where the company will look after servicing costs for five years or 50,000 miles and BMW Service Inclusive Plus which covers both service and maintenance costs over the same period.

Emissions summary

BMW M6 Gran Coupe emissions are officially rated at 232g/km of CO2, which isn’t going to keep too many polar bears happy but is actually very impressive for a 552bhp car with the performance to embarrass most supercars – especially considering the old 2005 M6 Coupe’s V10 emitted up to 352g/km of CO2.
