Costs & verdict
Everyday costs, plus how reliable and safe it is
The lack of diesel, hybrid and plug-in hybrid options for the Mazda 6 means that its economy and emissions look very high in a class that’s dominated by those more efficient engine types.
The most frugal member of the 6 family is also our favourite – the 2.0-litre petrol with a six-speed manual gearbox. It manages 152g/km regardless of which of the two power outputs you go for. We don’t yet have True MPG figures available for this engine, but the official economy of 42.2mpg is a long way off what the Skoda Superb 1.5 TSI manages.
Mazda as a brand finished in an impressive eighth place out of 30 manufacturers in our 2021 What Car? Reliability Survey – above Skoda in 12th. The 6 comes with a three-year or 60,000-mile warranty.
The 6 gets a full five-star crash test rating from Euro NCAP. The adult and child occupancy scores are very good for the class but the pedestrian protection is only average, and slightly behind that of the Skoda Superb Estate. Safety kit is impressive, and includes automatic emergency braking (AEB), blind-spot monitoring and lane-keeping assistance.
