Vauxhall Insignia come with significantly reduced CO2 emission and fuel consumption to the key models in Europe.

The well-known 2.0-litre Turbo petrol engine dropped the harmful emissions with 5 per cent on the Sports Tourer. The upgrades are mainly on the engine's engine management system.

The emissions of ecoFLEX have also dropped from 136g/km to just 129g/km, with a corresponding improvement in fuel consumption from 54.3mpg combined, to 57.6mpg. This means that not only is the ecoFLEX cheaper to run, but since it falls under 130g/km, customers will pay no VED for the first year.

Insignia Sports Tourer ecoFLEX has CO2 of only 134g/km and returns 55.4mpg. The power unit develops 160PS, with 350Nm of torque from 1750-2500rpm.

The 2.0 CDTi 160PS model emits just 144g/km of CO2 and the fuel consumption has dropped with 6.5 per cent.

The 130PS version of the diesel engine now has 11.5 per cent lower emissions – 136 g/km thanks to an all-new turbocharger.

Although, all engines have significant improvements in efficiency and refinement, the latest Insignias' cost the same on the road and are available to order from today.
