Fuel economy

A more stringent standard for fuel economy (WLTP) was introduced from September 2017, and this model was not required to undergo that test. Its fuel economy measured under the previous test system was 27 mpg. However these figures are less likely to be achievable in real world driving and so should never be compared to another car's mpg which was measured under the newer, more realistic WLTP system.

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.

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.

As long as you get it serviced regularly BMW M6 Gran Coupe reliability shouldn’t cause too much heartache. If you’re likely to take the car on track, inspect it thoroughly before and after to spot and rectify any issues early.

Optional service packages are available where for a reasonable sum BMW will look after servicing costs for five years/50,000 miles. The more substantial Service Inclusive Plus package can cover maintenance items including brake pads, discs and windscreen wiper blades.
