For such a large car with a range of relatively powerful engines, the 6 delivers very good fuel economy, but CO2 figures aren’t so impressive. The frugal star is the 148bhp 2.2 diesel, which pumps out 117g/km, making the 6 as cheap to run as a company car than any similarly engined rival. It managed 47mpg in our True MPG fuel testing – a decent effort.
The 6 is more expensive to buy outright than a Ford Mondeo and Skoda Superb. It also suffers from heavier depreciation than the Mondeo, so this might put private buyers off.
Entry-level SE-L Nav+ comes with dual-zone climate control, 17in alloy wheels, cruise control, front and rear parking sensors and an 8.0in colour infotainment system with DAB radio, Bluetooth and a USB connection. It’s brilliantly equipped, so unless you’re desperate for luxuries there’s little point in looking at the higher trims.
Move up to SE-L Lux Nav+ and it adds leather and electrically adjusted heated front seats and a reversing camera. Sport Nav+ gets 19in alloy wheels, an upgraded stereo and keyless entry, while range-topping GT Sport Nav+ features a 360deg camera, a 7.0in digital driver display, heated rear seats and ventilated front seats. It’s worth pointing out that the resolution for the reversing and 360deg cameras are terrible; it’s like you’re watching a video from 1994.
Mazda finished joint 11th out of 31 manufacturers in our 2018 reliability survey, while the 6 itself beat the likes of the Audi A3 saloon and Skoda Superb to come in third in the executive car class. Every 6 gets a three-year or 60,000-mile warranty, matching that of rivals.
Euro NCAP has given the 6 its full five-star crash test rating. This was a few years ago, though, and Euro NCAP has since tightened its testing criteria, meaning its category scores can’t really be compared with those of, for instance, the Skoda Superb, which also scored five stars. The 6 does get a very impressive amount of safety kit as standard, though, including automatic emergency braking, blindspot monitoring and lane-keeping assistance.
