2012 Vauxhall Insignia on sale this month

Vauxhall has revamped the engines available in the Vauxhall Insignia hatchback, saloon and Sports Tourer (or estate) for 2012.

The Insignia has been a big success for Vauxhall since replacing the Vectra and regularly appears in the top ten best-sellers, outselling its key rival the Ford Mondeo in recent years.

Now Vauxhall has capitalised on its popularity by introducing its much-vaunted Ecoflex signature to the range.

The Ecoflex name means more efficient diesel engines and that is the case with the Insignia. A 2.0-litre CDTi engine has been made available in 130PS and 160PS configurations in the new 2012 Insignia.

In all three body styles the engines deliver sub-120g/km of CO2 emissions and subsequently qualify for zero first year road tax. This is achieved through tweaks to the engine design, aerodynamic features such as low-rolling resistance tyres and Start/Stop technology as seen in the likes of the Vauxhall Astra and Vauxhall Corsa.

However, Vauxhall has not neglected its petrol offering. A new 1.4-litre turbocharged engine replaces the 1.8-litre currently available.

At 140PS, output remains the same but the smaller engine increases fuel economy by a third to 50mpg and reduces CO2 emissions by 25 per cent to just 134g/km.

Vauxhall has not ventured into a redesign of the exterior for 2012, but some more gadgets are now available inside in certain specification levels.

These include a new front camera capable of recognising traffic signs and relaying the information to a screen on the dashboard. It will also alert the driver if the car in front is too close.

Other equipment include a revamp to the ‘infotainment’ system to include points of interest along a route and advice on avoiding heavy traffic and saving fuel.

The new Vauxhall Insignia will go on sale towards the end of September, but order books are now open for the 2012 model year car.
