We'll start with our own experiences first: The 1.2 - litre PureTech 110 gets an official combined economy figure of 65.7 mpg, and in mixed driving we saw MPG in the high 40s, so mid-40s is a realistic estimate and 50 - plus if you have a particularly light right foot. (evo.co.uk)
As with all fuel economy figures, you'll struggle to achieve those quoted stats, but the 60hp engine will be harder than the others in real driving conditions unless you have an extremely light right foot. (nextgreencar.com)
It's a useful refresher, and the inevitable whiff of driving test emphasises the need for a light right foot if you want to make smooth progress in traffic in the Astra. (evo.co.uk)
