The entry-level three-cylinder 1.2-litre petrol unit is surprisingly lively given its meagre power but although it’s fine once up to speed, it struggles a bit when the car’s fully loaded. The supercharged 1.2 DiG-S petrol is stronger but still has to be worked quite hard to make decent progress. The 1.5 diesel’s extra torque is useful, and it pulls well if you keep it in its sweet spot, which sits lower down the rev range than the petrol engines’. It quickly runs out of puff at high revs, but it happily keeps up with traffic on the motorway.
Low-mileage drivers will be best off with the higher powered petrol engine. Those who regularly drive with a full load on the motorway, or who cover high mileages (over 15,000 miles a year), should plump for the diesel.
