Vauxhall Corsa beats the congestion charge

Changes to the criteria for free use of London’s roads came into force on 1 January, allowing all cars emitting 100g/km exemption from the charges, which rose from £10 to £12 for 2011.

All cars must also comply with Euro 5 air quality standards which cover pollutants such as NOx and harmful particulates – or soot.

Vauxhall’s low-CO2 ecoFLEX range of diesel engines now boasts eight models of the popular Vauxhall Corsa supermini that are exempt from paying the charge.

While many manufacturers have a single eco-leader falling below 100g/km, three- and five- door models of the Vauxhall Corsa 1.3 CDTi ecoFLEX are available in a variety of specifications to match the criteria.

These include the most eco-friendly model in the range, the three-door Vauxhall Corsa S, which emits 94g/km and is capable of delivering 78.5g/km on the combined cycle.

These figures are achieved through the use of fuel saving technologies such as Start/Stop and lighter materials to reduce the overall weight of the car.

Duncan Aldred, Vauxhall’s Managing Director, said: "Not only do our Corsa ecoFLEX models ease the pain of ever increasing fuel costs, but some models are now set to save London commuters even more expense."

The 100 per cent discount from the London Congestion Charge is available for eight Corsa models, split evenly between three- and five-door models and covering S and Exclusiv trim levels offered with the 1.3 CDTi 95PS diesel engine.

The congestion charge-beating Vauxhall Corsa prices start from £14,080 on the road and finish at £15,580 for the five-door model in Exclusiv trim.

The Vauxhall Corsa ecoFLEX is available from Perrys Vauxhall dealers across the country.
