Vauxhall has added a lower emission ecoFLEX option to its Astra range. Available as three- or five-door hatchback, and an estate, each ecoFLEX Astra emits just 119g/km CO2 thanks to a frugal 1.7-litre turbodiesel. Using common rail fuel injection technology, the engine produces a useful 108bhp yet Vauxhall’s figures predict a combined average of 62.8mpg.
EcoFLEX Astras are based on ‘Life A/C’ trim (which includes air conditioning) but ecoFLEX adds a six-speed gearbox with special ratios, low rolling resistance tyres and a particulate filter to remove nasties from the exhaust.
The ride height is also reduced to improve the aerodynamics. Its low CO2 output means VED (Vehicle Excise Duty, or road tax) of just £35 a year.
However, with prices starting at £16,340, it’s not particularly cheap compared with rivals like the Fiat Bravo Active Eco (£14,200) and VW Golf Bluemotion (£15,595). Haggle hard for a discount. Or read more about the alternatives in our Fiat Bravo first drive and VW Polo Bluemotion first drive
Further down the Vauxhall range, the Corsa ecoFLEX uses a 74bhp 1.3-litre diesel to achieve 119g/km. It’s now available in high-spec Design and SXi trims, in addition to the existing Life and Club versions.
Additionally, the 1.3 diesel and 1.0 petrol Agilas will now also feature the ecoFLEX badge.
