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 31 - 47 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.

Lower depreciation than most mainstream large cars and competitive list prices mean the Mazda6 is good value. Fuel consumption is average, but maintenance costs are relatively low.

6 performs quite well on the eco front. With an average of 188 g/km CO2 across the range, its emissions are fairly standard for a medium-sized saloon. However, it’s worth noting that the line up has a high number of diesel models, bringing the average down and giving buyers more choices of low-emission versions. Diesels typically produce less CO2 than petrol engines with similar power outputs.

The range is not particularly economical, averaging 38 mpg.

The Mazda6 has been quite a reliable car. The interior should also stand up well to general wear and tear.
