Greener versions of the Vauxhall Corsa could save car buyers money thanks to a range of improvements making it cheaper to run.
The major money saver of all the models is the latest version of the diesel ecoFLEX model which has emissions of just 98g/km CO2 and can achieve an official average of 76mpg.
However, compared to the current 75bhp ecoFLEX, these results are achieved despite a power boost to 95bhp.
The revised range is on sale from April 2010, and it means many versions of the Corsa - all those with CO2 emissions at 130g/km or below - will benefit from free road tax for a year when bought new because of changes to Vehicle Excise Duty (VED) being introduced next year.
The 98g/km ecoFLEX model will continue to be free to tax afterwards, while other versions with CO2 emissions up to 120g/km will benefit from a low rate of Vehicle Excise Duty, also known as road tax.
To further maximise fuel efficiency the Corsa will also get a gearshift indicator to tell the driver the best time to change gear.
As well as the fuel consumption and emissions improvements there have also been changes made to the car's steering and suspension set-up, which Vauxhall claims will help improve the car's ride and handling.
The SE, SXi and SRi all get cruise control and trip computer as standard. For the first time ever in the UK for a small car, the Corsa SE also gets heated leather steering wheel and heated front seats as standard. Heated steering wheels is something only usually found on top-end luxury cars such as Range Rovers and BMW X5s.
Prices for the new Corsa will start from £10,285.
