MPG and runnings costs
Even the least fuel efficient variants, in the shape of the 59bhp manual and 74bhp automatic, achieve returns of 64.2mpg on a combined cycle. The leanest runner is the 74bhp manual model, that returns 68.9mpg on combined cycle.
All the models fall into two VED brackets, although the difference of £25 between the dirtiest and cleanest models is unlikely to influence you one way or the other. Service intervals are every 10,000 miles and the Citigo should be light on consumables.
