Mazda6 Tourer estate (2012-2022) review - MPG, running costs & CO2

The Mazda6 Tourer is quite efficient for a car of its size, but it’s petrol only

MPG, running costs & CO2 Rating

3.5 out of 5

Instead of focusing on just one area to improve the efficiency of its cars, Mazda has chosen an all-round approach it calls SkyActiv. That means the car has a lighter and stronger body than its predecessor, as well as lighter components and hi-tech, ultra-efficient engines. All models also come with i-Stop, Mazda’s stop-start technology, which rests the engine when the car is at a standstill to reduce fuel consumption. Every engine besides the entry-level petrol also comes with ‘i-Eloop’ brake regeneration that saves a little bit of energy.

Mazda6 Tourer MPG & CO2

We used to recommend the diesel engines which are no longer available new, but the petrols are certainly well worth considering if you’re not planning to rack up lots of miles. The 2.0-litre petrol engine, with 143 or 163bhp, can return 41.5mpg and CO2 emissions of 155g/km, and you should be able to achieve these figures in real driving. Because CO2 emissions are now rated on the stricter WLTP system, it means the Mazda6 Tourer is no longer so appealing to company-car drivers. Both these petrols sit in a high Benefit-in-Kind (BiK) band, which is why we’d recommend a plug-in hybrid like the BMW 330e Touring or Peugeot 508 SW for business drivers.

The 2.5-litre petrol is bigger in size than many rivals’ engines, but this engine (limited to top-spec cars) isn’t too far behind at 37.2mpg. Its CO2 emissions put it in the highest business tax band.

The diesel engines are likely to be less expensive to run for most drivers, so are worth seeking out by used buyers. The 148bhp engine can return 53.3mpg, with CO2 emissions of 141g/km. These figures change a little for the slightly less economical Sport Nav+ version, which was also available with the 181bhp diesel. We like the extra overtaking power of this engine, and it’s barely less economical at 51.4mpg.

Insurance

Even with impressive performance figures across the range, the Mazda6 Tourer broadly matches the insurance costs of the Ford Mondeo Estate. Sitting in group 19, the 143bhp petrol Mazda6 SE-L offers the cheapest premiums, while the top-of-the-range 181bhp GT Sport diesel has a group 27 rating.

Servicing

All Mazda6 Tourers will need to be serviced every year or 12,500 miles, whichever comes first. A three-year service plan costs £679 for petrol models and £779 for diesels, but Mazda lets you pay for your car’s maintenance in low monthly instalments.

Warranty

All Mazdas get a three-year/60,000-mile warranty, which is similar to most of its rivals, although the smaller Kia Ceed Sportswagon and Toyota Corolla Touring Sports have much longer warranties if you’re planning to keep the car a long time and can live without some of the Mazda’s extra space.
