The Hyundai i10 isn’t going to set any land speed records, but what’s more important to city car buyers or perhaps those on a tighter budget is its ability to deliver great efficiency, leading to low running costs. 

The i10 is one of the cheapest new cars on sale in the UK right now, with the range starting from around £15,000. Alternatively, you should be able to find a lease deal for one well under £200 a month without having to fork over an enormous initial payment, either.

The small-capacity petrol engines that power the i10 return decent fuel economy and relatively low CO2 emissions. The base 1.0-litre unit with 66bhp achieves a claimed 55.3mpg on the combined WLTP test cycle and emits 116g/km of CO2 in entry-level Advance trim with the five-speed manual gearbox. The slightly larger 1.2-litre motor with 83bhp offers an average of 54.3mpg, again in entry-level spec, with emissions standing at 119g/km.

Opting for the five-speed automated manual with either engine causes fuel economy to dip slightly to 52.3mpg and CO2 emissions to rise to 122g/km. 

When we tested a 1.2-litre i10 with the manual gearbox we managed to average 53.1mpg, compared to the 51.9mpg we got from a Toyota Aygo X during the same group test. 

Even the sportier N Line version, with its 99bhp turbocharged 1.0-litre petrol engine, promises impressive fuel economy figures of up to 52.3mpg and CO2 emissions of 123g/km. After covering nearly 450 miles in an i10 N Line, we achieved an average of 42.3mpg – exactly 10mpg short of Hyundai’s claimed stat, but still very respectable for a souped-up city car.

Insurance groups

If you’re worried about how much it’ll cost to insure an i10, you’ll be reassured to learn that the entry-level 66bhp 1.0-litre car sits in insurance group 4 out of a maximum 50. Even the boy racer-esque N Line version should be relatively inexpensive to cover as it only sits in group 10.

In comparison, the Kia Picanto range starts from group 5 and tops out at group 11, although the Toyota Aygo X manages to fall in just groups 5 or 6.

Our latest expert data suggests that Hyundai’s city car will hold onto an average of 53 per cent of its original list price after three years of ownership and 36,000 miles on the clock come trade-in time. Its Korean counterpart, the Kia Picanto, is a similar performer on the used market, although it’s expected to retain an average of 49 of its list price after the same three-year period.
