What is it?
Vauxhall’s take on the familiar eco-car recipe. Take your all-new model, add tall gearing and a small diesel engine and you have a very frugal car. This is exactly what Vauxhall has done with the Astra EcoFlex, with a 94bhp 1.2-litre turbodiesel motor and a five-speed gearbox.
What’s it like?
Producing this sort of model makes a lot of business sense and occasionally makes a very nice car, but often it results in an underpowered engine hampered even more so by the gearing. This is exactly what you have with the new Astra EcoFlex. At a steady cruise on the motorway or at urban speeds the engine settles and it’s easy to appreciate the Astra’s supple ride and an interior that avoids the piously basic finish that some rivals get.
But gathering momentum requires a lot of patience. The tiny turbodiesel motor struggles to tow the burden of the heavy Astra if you want to make normal progress through traffic, forcing you to work the engine beyond 2500rpm much of the time - harder than would be necessary with a bigger or more powerful unit.
