3.5 out of 5

The cost of owning a BMW 6 Series coupe largely depends on which model you buy. The diesel 640d will naturally be the cheaper option overall, so the choice depends on what you want from your coupe and whether running costs are a major concern or not.

If the high initial purchase price isn’t enough to make you look elsewhere, the 6 Series offers stellar resale values.

BMW 6 Series coupe MPG & CO2

Out of the three engine variants available, the 3.0-litre diesel 640d is the most economical by a considerable margin. Fuel economy stands at 52.3mpg, and emissions are at a relatively low 143g/km given the 6 Series’ size and performance, but this is for the SE version on smaller wheels. It goes up to 147g/km for M Sport models with larger alloys.

Though the base model 640d is around £3,000 more than the basic petrol-engined 640i, it’s widely considered to be the best investment for owners covering big miles and company car drivers. Road tax is £130 per year and benefit-in-kind stands at 27%. However, despite being the most economical model in the range, the comparable Mercedes E-Class coupe hits a higher figure of 60.1mpg, while CO2 levels are at a lowly 122g/km if you go for the BlueTEC diesel.

A 3.0-litre six-cylinder petrol engine in the 640i and 4.4-litre V8 engine in the 650i models form the petrol options. The 640i is the cheapest model in the entire range, priced at around £60,000, but the higher running costs derived from this model’s 37.2mpg and high CO2 emissions of 176g/km (180g/km with larger wheels) will eventually negate any initial savings on the cost price.

The 4.4-litre V8 in the 650i is purely reserved for those looking for a little extra excitement in their life. The most expensive M Sport model is priced at £72,000 and comes with a hefty road tax figure of £265 per year.

Insurance

All three variants of the 6 Series coupe fall into the highest insurance category, at group 50, so expect to pay a sizable amount of money for insurance bills.

Warranty

All 6 Series models have a three-year warranty that is offered with unlimited mileage.

Servicing

BMW offers servicing packages for the 6 Series coupe starting from £525 for the Service Inclusive package, which offers MOT cover, oil changes, brake fluid top-ups and vehicle service checks.
