You can choose from a trio of 1.0-litre three-cylinder petrol engines: one with 59bhp, another with 74bhp and a turbocharged version with 89bhp. The two lower-powered engines are a little weedy, so we'd recommend paying for the more powerful car. It brings much punchier acceleration, particularly from low revs, making the Up far more relaxing to drive and a much more competent motorway car.
Both non-turbocharged engines are available in regular or Bluemotion Technology form, the latter of which improves fuel economy and cuts CO2 emissions by switching off the engine whenever you come to a stop. The turbocharged 89bhp engine gets this stop-start system as standard.
There’s also an all-electric version, called the e-Up; it actually accelerates more quickly than all but the most powerful of the conventionally propelled models and feels genuinely nippy around town.
