The Ka+ comes exclusively with a 1.2-litre petrol engine, but you do get a choice of two power outputs: 69bhp or 84bhp. So far, we’ve only tried the more powerful of the pair, but even with that option, the Ka feels really very slow, even for a cheap supermini. The engine needs lots of revs to achieve even moderate acceleration, and even then, it feels pretty breathless. It’ll just about keep up with most motorway traffic, but if you find yourself having to slow down for any reason, it’ll take a fair old while to get back up to speed. The engine doesn’t make a particularly pleasant noise when you work it hard, either, but the volume always stays low and you don’t feel much vibration from it, which helps towards the car’s overall impressive level of refinement.
