What are the running costs?

The i20 is a small, light supermini equipped with a mild-hybrid system, so it should be easy on your wallet at the pumps. Hyundai says the entry-level manual model will return 55.4mpg on the WLTP combined cycle – and every model in the car’s line-up has a claimed economy figure of more than 50mpg.

Automatic models are marginally less economical than the manuals – and fuel consumption increases gradually as you climb up the i20’s range, adding larger alloy wheels and more equipment. However, drive carefully, and the trip computer will regularly display an average figure in the high-40/low-50mpg bracket.

CO2 emissions are low across the line-up, ranging between 118–122g/km depending on the trim-level and gearbox. That means annual road tax is cheap. You can view detailed MPG and CO2 figures on the Hyundai i20 specs page here.

Servicing and warranty

Hyundai’s five-year warranty isn’t quite as long as the seven-year plan offered by its sister brand Kia – but i20 buyers can cover an unlimited number of miles during that five-year period and the car will still be covered. Buyers also get a roadside assistance plan and five annual vehicle health checks thrown in as part of the package.

Buyers can use Hyundai’s online tool to specify a tailored service plan for their car. We filled the form out for an i20 N Line and received a three-year plan that included three MOTs and three services, with the cost spread over 23 payments of around £30.


The Hyundai i20 has only been on sale since 2020, so it’s still too early to make informed judgements about its long-term reliability. Hyundai’s other cars have proven to be pretty bulletproof, though – and we’re expecting a similar record from this supermini.

It’s also worth bearing in mind that every i20 on the road today is still covered by Hyundai’s five-year warranty. So, even if you’re buying nearly new, you won’t have any enormous repair bills to worry about until 2025 at the earliest. Just make sure you take the car back to an approved Hyundai dealer for its services and repairs so you don’t void the warranty.
