Lowest-CO2 Vauxhall Corsa

(Monday 15 October 2012)

Vauxhall has done some work to improve the fuel economy and lower the CO2 emissions of what was already its greenest model. The Corsa 1.3 CDTI ecoFLEX with start/stop has had its engine management system retuned, and is now fitted with a variable displacement oil pump that provides only as much oil pressure as the engine needs in a given situation.

These changes, plus the use of lower-viscosity transmission oil, mean that the three-door now has combined fuel consumption of 85.6mpg and CO2 emissions of 88g/km, with the heavier five-door not far behind at 83.1mpg and 89g/km. The previous best figures for the Corsa were 80.7mpg and 94g/km.

Elsewhere in the range, all Corsas other than the VXR Nürburgring Edition (did we mention we'd competed in a hillclimb with that one?) have had their suspension modified to provide a more comfortable ride. Vauxhall has also developed the manual transmission fitted to lower-spec models for better shift quality, particularly at cold temperatures.
