Vauxhall Insignia cleans up

Vauxhall's Insignia range will now feature a diesel version with carbon dioxide emissions of less than 120g/km.

The Ecoflex diesel model has a 128bhp 2.0-litre engine and, for the first time in an Insignia, stop-start technology. It has also been given aerodynamic tweaks and low-rolling-resistance tyres. These which help contribute to the car's emissions of 115g/km and an expected average economy of 63mpg.

The car falls into the lowest (13%) company car tax band and costs from 20,345.

Vauxhall is also offering a new 1.4 turbo engine in the Insignia. It's capable of 51.4mpg and emits 129g/km of CO2. Prices start at 18,680.

Both versions are available to order now.
