The recently-launched Vauxhall Corsa and Astra ecoFLEX models, both with a 1.3 CDTi 95PS engine, are about to become the most popular Vauxhall models in the UK.
Vauxhall says the popularity of the models, which boast CO2 emissions as low as 98g/km and combined fuel economy of 76.3mpg, is down to the low costs of owning one.
The Corsa and Astra models are exempt from first year VED under the new government tax rates and lower fuel consumption lead to reduced running costs, says Vauxhall.
All ecoFLEX models feature technology to improve fuel economy such as ultra-low rolling resistance tyres, modified gearing, revised fuel mapping and an aerodynamic exterior.
Vauxhall has also announced it will introduce fuel-saving Start-Stop technology across the ecoFLEX range. The first model to be fitted with the system will be the Corsa in September.
‘Eco’ ranges are becoming more prevalent in recent years, and Ford, Seat and Citroen all have their own iterations of the Eco name.
Most models, such as the Ford Focus ECOnetic, boast Start-Stop technology and sub-100g/km CO2 emissions.
Vauxhall alone offers 50 different ecoFLEX models in all but two of its ranges and sales of the range has reached 7,000 this year.
The manufacturer will reduce emissions further when the extended electric hybrid Ampera arrives in UK showrooms in 2012.
