Power of 6

Can a bigger diesel propel the Mazda 6 ahead of Vauxhall’s Insignia?

Choosing your perfect partner in the family car class is far from straightforward. While the all-conquering Ford Mondeo rules the roost, a host of alternatives vie for your attention, each with their own unique range of talents.

The Mazda 6 is one of our favourites in the sector, and after running one for a year, we know it’s more at home on twisty back roads than it is trawling the motorway network. The 2.0-litre diesel engine of our long-termer simply didn’t cut it against the best of the competition, though.

For that reason, the arrival of the firm’s new 161bhp 2.2-litre oil-burner is big news. To find out if the 6 now has the firepower to take on the class leaders, we’ve lined up one of the latest arrivals.

The Vauxhall Insignia looks more like a prestige saloon than a mainstream family hatch, and it comes with a 2.0-litre diesel engine that on paper promises to match the 6 blow-for-blow.

The SE Nav spec model tested here has a comparable standard equipment list, but the Insignia is more expensive than its mid-range Mazda TS2 rival. What it does come with is a luxurious cabin that has been designed to meet exacting European tastes, plus a reputation as an incredibly refined cruiser.

Is it good enough to take victory against the Mazda, or does the new engine transform the 6 into a family car front-runner?

Verdict

THESE two cars are very different members of the family hatch class. When it comes to showroom appeal, the Insignia is the clear leader. Its smart looks and quality interior will be more familiar to the owner of a compact executive saloon than someone who drives a family hatchback. But don’t be put off by the plain styling of the Mazda, because on the road, the tables are turned.

The 6 is better to drive, thanks to its lively new engine and sharper dynamics, while the Vauxhall’s supple suspension and quiet cabin make it one of the sector’s most refined cars.

So, which gets the nod? There’s no denying the Insignia’s class, but it’s hard to ignore the fact it’s nearly £3,000 more expensive and has higher emissions than its rival. So helped by its more entertaining handling and stronger performance, the top-value 6 takes the win.
