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, despite the fact that the Superb is a little faster.
Those emissions also make the 6 an expensive option for company car buyers, and it’ll also cost more to buy outright than the Ford Mondeo and Skoda Superb. Monthly finance deals tend to be very competitive, though, and Mazda routinely offers low deposit, interest-free deals.
The entry-level SE-L comes with dual-zone climate control, 17in alloy wheels, cruise control, front and rear parking sensors, LED headlights and an 8.0in colour infotainment system with DAB radio, Bluetooth, sat-nav and phone mirroring. With this generous list of standard equipment, there seems little point in looking at the higher trims.
Sport adds leather upholstery, electrically adjusted heated front seats, keyless entry, a reversing camera and 19-inch alloy wheels. GT Sport gets the full deluxe spec, with a sunroof, 7.0in digital driver display, 360-degree camera, heated rear seats, ventilated front seats and even some Japanese wood trim around the dash. It’s only available with the 2.5-litre petrol engine, though, and is a big price jump from the lower spec models.
Mazda as a brand finished 9th out of 31 manufacturers included in our 2020 What Car? Reliability Survey, and the 6 itself came an impressive third – just ahead of executive car alternatives such as the Mondeo and the BMW 3 Series. It gets a three-year or 60,000-mile warranty, matching that of rivals.
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 a Skoda Superb Estate. Safety kit is impressive and includes automatic emergency braking (AEB), blind-spot monitoring and lane-keeping assistance.
