VAUXHALL has confirmed the new Corsa ECO, which will make its world debut at the Frankfurt International Motor Show next month, will go on sale in the UK next year.

Using the three-cylinder 1.0-litre ECOTEC engine, the Corsa Eco will use aerodynamic modifications and an Easytronic gearbox to help it achieve a combined fuel consumption figure of 56.6mpg and carbon dioxide emissions of 120g/km.

The sequential manual gearbox with an automatic change function has been programmed so the engine will run in the lowest fuel consumption range, but will kickdown when required for overtaking. The aerodynamic changes means the Corsa ECO will reach 100mph - 4mph faster than the standard Corsa 1.0-litre.
