BMW 6-Series M6 Convertible (2012-2018) running costs and reliability
Miles per pound (mpp)
Fuel economy
BMW has gone to great lengths to cut emissions and fuel consumption. When you consider that the previous model’s claimed average fuel consumption was around 19mpg, this version’s official average of 27.4mpg is pretty impressive. In real-world driving though, you’ll be lucky to get 20mpg. BMW M6 Convertible running costs won’t be cheap right across the board: BMW’s servicing costs among the highest and it’ll be expensive to maintain as well.
Tyres will be pricey and the high CO2 emissions make it expensive to tax.
You’ll not be doing icebergs in the Arctic Circle much good if you buy one of these because official BMW M6 Convertible emissions make unpleasant reading. The previous M6 droptop’s CO2 emissions were a planet-melting 342g/km and this car’s 232g/km do represent a massive improvement. Still, this is not a car to take to the Greenpeace annual get-together.
Our test car seemed pretty bulletproof and fit and finish was impeccable. If you do get some irritating rattles inside your M6 you will have been very unlucky. The V8 engine has proved robust on the M5 so mechanical woes should be few and far between. Customer service surveys have revealed that BMW owners are a happy bunch so you should expect trouble-free motoring.
