There are five engines in the C3 range, but so far we’ve only driven three of them: these are the three-cylinder 1.2-litre Puretech petrol engines, in outputs of 81bhp and 109bhp, and the 1.6-litre BlueHDI diesel with 99bhp.
The lower-power version feels fine for pottering around town, but on the motorway it starts to run out of puff. To make any decent progress, you’ll need to rev it very hard. As it doesn’t come with start/stop technology like the 109bhp Puretech, you do feel vibrations through the seat and steering wheel when you’re stationary.
So if you regularly travel the highways and byways outside the city, we’d recommend plumping for the 109bhp model. Although at its core this is basically the same engine as above, a turbocharger adds a bundle of helpful extra pace. Not only is it punchier on all roads, its extra performance is available from much lower revs, making it considerably more relaxing to drive.
As for the diesel, it has plenty of power that makes getting up to speed and staying there easy. It does send quite a lot of vibration though the controls at idle and you’re always aware that it’s a diesel, though. Considering the high purchase price, we’d avoid unless you do an awful lot of miles.
