Vauxhall has reduced the CO2 emissions of its Insignia ecoFLEX diesel model by 10 per cent, from 129 g/km to 115 g/km.
There’s also a new 1.4 Turbo petrol engine which emits just 129 g/km of CO2 along with 51.4mpg in the hatchback and saloon.
The 2.0 CDTi ecoFLEX’s CO2 savings are achieved in part by the inclusion of Start/Stop technology, available for the first time on an Insignia, along with underbody aerodynamic measures and low rolling resistance tyres.
The Insignia’s two revised Euro 5 compliant 2.0 CDTi diesel engines are available with 130 PS or 160 PS power outputs. Even fitted with the lower-powered 130 PS engine, the Insignia ecoFLEX achieves a top speed of 129 mph, with 0-60 mph taking just 10.4 seconds.
The 160PS variant is still quicker, posting a 137 mph top speed and 0-60mph in 8.9 seconds. Torque is also maintained against the outgoing model with 300Nm for the 130PS engine and 350Nm on the 160PS unit.
The new-to-range 1.4 Turbo petrol engine has improved torque, from 175Nm to 200Nm.
The new Insignia ecoFLEX diesel now falls in to the lowest 13 per cent Benefit-In-Kind tax band for the first time, and there is no VED on the hatchback and saloon, and no VED in year one on the Sports Tourer .
The 1.4 Turbo petrol engine also offers low 15 per cent BIK for the 2011/12 tax year.
The new Insignia models also benefit from updated 18-inch five spoke alloy wheels and the inclusion of new satellite navigation units, Navi600 and Navi900. The Navi600 offers UK and Ireland mapping and main road networks across Europe, whilst the Navi900 features detailed European mapping.
Prices for the sub-120g diesel models start from £20,345 for the ES 2.0 CDTi (130PS) ecoFLEX Start/Stop Hatchback and go up to £29,385 for the top-of-the-range SRi Nav Vx Line Red Sports Tourer (160PS) ecoFLEX.
The 1.4 Turbo is priced from £18,680 for the ES Hatchback up to £27,110 for the SRi Nav Vx Line Red Sports Tourer.
Vauxhall Insignia Exclusiv 1.4 Turbo Start/Stop – a downsized 1.4 litre turbo easily outperforms the 1.8 litre it replaces whilst also being much more efficient.
Vauxhall Insignia BiTurbo – a twin-sequential turbocharged diesel engine with nearly 200 PS yet emissions as low as 129 g/km CO2
