Reset the trip computer in a Vauxhall Insignia Ecoflex and even without making an effort to conserve fuel, you’re likely to better 50mpg. You can better 60-to-the-gallon with a bit of commitment, and while the 75mpg average that Vauxhall claims is fanciful in the real world, that's still very strong economy for a car this size.

On carbon emissions, meanwhile, the Ecoflex models are outstanding in the class, and the more powerful diesel is also very commendable, allowing you to combine 168bhp with 114g/km.

The Insignia sits in a market segment so dominated by fleet sales that running costs are king

The 1.4-litre petrol unit is also strong. CO2 emissions from 124g/km are good for a petrol-engined car of this size, and official fuel consumption figures of 53.3mpg on the combined cycle is competitive too. Vauxhall quotes almost 40mpg figures for the 247bhp 2.0-litre model, but in reality you're more likely to return very low 30s-to-the gallon.

The Insignia sits in a market segment so dominated by fleet sales that running costs are king and every new model must further improve matters. So on price, maintenance schedules and costs, insurance and ease of repair, it offers nothing less than all-round competitiveness.

More in some ways; as part of the last refresh, Vauxhall brought every model in the range down by two insurance groups, and it has been tackling its long-standing depreciation problem quite successfully since the end of the last decade.
