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.
