Despite the improvement in fuel consumption and emissions, the ecoFLEX packs 21 per cent more power from its 1.3 CDTi turbodiesel engine, its output rising from 75 to 95PS. Torque is also up by 20Nm to 190Nm available at just 1750rpm, allowing drivers the kind of flexibility normally vacant in eco-class cars.
To achieve this rare combination of performance and frugality, the Corsa ecoFLEX's 1.3 CDTi now employs a variable geometry turbocharger which significantly improves both performance and efficiency. To support the higher turbo pressure, the compression ratio has also been reduced from 18.0 to 16.8:1, while the injection system's calibration has been revised to boost low-end torque and peak power.
As a result, the Corsa ecoFLEX's performance is enhanced further, despite using taller gearing. It will now accelerate from 0-62mph in 12.3 seconds and reach a maximum speed of 110mph.
Using the chassis and aerodynamic modifications from the current Corsa 105g/km model, the new ecoFLEX also benefits from a 20mm lower ride height than standard and in Life trim gets 175/70 low-rolling resistance tyres on 14-inch steel rims (Club models get 15-inch steel rims with alloys as an option) and aero-optimised wheel trims.
The Corsa ecoFLEX is available in Life and Club trim only. Full pricing will be announced soon.Vauxhall launches most economical car
