You can choose from a quartet of 1.0-litre three-cylinder petrol engines: one with 59bhp, another with 74bhp, a turbocharged version with 89bhp and a finally a 113bhp turbo.
The two lower-powered engines are a little weedy, so we'd recommend paying for the 89bhp version. It brings much punchier acceleration, particularly at low revs, making the Up far more relaxing to drive and a much more competent out-of-town car.
All engines are available in regular or stop-start (S/S) form, the latter of which improves fuel economy and cuts CO2 emissions by switching off the engine whenever you come to a standstill.
The 113bhp engine is exclusively offered in the range-topping Up GTI and can propel the tiny car to 62mph in just 8.8sec.
There’s also an all-electric version called the e-Up. It feels genuinely nippy around town, although acceleration quickly tails off above 40mph.
