Hyundai i20 review - MPG, CO2 and Running Costs

Both engines are frugal enough in the real world, but the 1.0-litre has more competitive CO2 figures

The 1.0-litre three-cylinder models are the most frugal units on paper, with the older non-turbo 1.2 models delivering only similar numbers, despite their performance deficit. The lesser powered 1.0-litre unit achieves figures of 56.5mpg and 114g/km, whether equipped with the manual or the automatic gearbox. The 118bhp version is only marginally less frugal in official tests, capable of 54.3mpg and 118g/km.

The 74bhp and 83bhp 1.2-litre petrol sit pretty much between the two for efficiency with both variants achieving 55.4mpg and CO2 emissions of 119g/km.

Those numbers for the 1.0-litre unit aren’t quite on par with its rivals. The 1.0-litre TSI version of the Volkswagen Polo produces a similar 114bhp, yet hits 60.1mpg, while Ford claims that the Fiesta EcoBoost with 123bhp will top 65.7mpg. A Peugeot 208 is also more fugal on paper: its 1.2-litre Puretech engine achieves 62.8mpg and CO2 emissions of 103g/km.

Insurance groups

Choose the most powerful engine in the i20 range, and you're still only looking at a group 11 rating. That's a good 4-5 insurance groups below rivals like the VW Polo and Citroen C3, even though the i20 is a more powerful car. The lowest-rated 1.2-litre is just group four and the slightly more powerful version groups six and seven, both of which should make them ideal choices for new or inexperienced drivers.


Even with the more powerful 1.0-litre engine, the Hyundai i20 compares favourably with it rivals when it comes time to sell on. Predicted residuals 43.5 per cent are close to the 44 per cent the VW Polo 1.2 TSI is expected to hold on to after three years. And this is far better than the Citroen C3, which offers a low 32.7 percent rating.
