The Vauxhall Corsa ecoFLEX now emits 88g/km of CO2, making it the lowest emitting Vauxhall diesel ever.
The three-door Corsa fitted with Vauxhall’s stop-start-equipped 94bhp 1.3-litre diesel engine now achieves 85.6mpg while emitting 88g/km, making it 2.4mpg more efficient and 6g/km cleaner than the previous model. The five-door version of the 2012 Corsa ecoFLEX is said to manage 83.1mpg and 89g/km.
However, the cleanest Corsa is narrowly beaten by the forthcoming facelifted Ford Fiesta Econetic, which returns the same mpg, but manages 87g/km CO2 emissions from its 1.6-litre diesel engine. And both cars are beaten by the 1.1-litre Hyundai i20 Blue, which returns 88.3mpg and emits 84g/km of CO2.
In order to achieve these economy improvements, the uprated Corsa gets a variable displacement oil pump that delivers only the necessary oil pressure. The use of special low-viscosity transmission oil also contributes to efficient fuel consumption, as does revised mapping for the engine’s ECU.
From 1 November, the Corsa also benefits from a new manual gearbox, which Vauxhall promises gives smoother shifts and easier use when the transmission is cold. The Corsa also comes with improved low-rolling-resistance tyres.
Aside from improving the economy of the 1.3 diesel model, Vauxhall has also introduced improved suspension and damper settings for all Corsa models (except the VXR Nurburgring Edition) aimed at improving ride comfort.
