Hyundai i20 review - MPG, CO2 and running costs

Single engine option is no barrier to economy, with low fuel consumption and emissions.

With just the one engine and a pair of transmissions you get what you’re given when it comes to economy, though thankfully the i20 is respectably frugal – and indeed, nearly identically frugal regardless of whether you opt for the manual or DCT automatic. The important figure is the WLTP combined fuel economy rating of 55.4mpg. Premium and Ultimate versions take a small hit on their larger wheels, at 54.3mpg for the manual and 53.3mpg for the DCT.

That’s a touch more than a Renault Clio with the TCe 100 engine, but despite the i20’s hybrid tech, it still can’t quite match the few remaining diesels in this class – the diesel Clio, for comparison, manages 67.2mpg.

Hybrid tech does result in low CO2 emissions figures, however, at 115g/km for the manual and 117g/km for the DCT. Premium and Ultimate versions emit a touch more, but not enough to change their tax bands. As an alternative fuel vehicle that means a first-year bill of £165 for all i20s, and £140 per year thereafter. The numbers do have a slight effect on BIK rates for company users, with most i20s in the 28 per cent band but Premium and Ultimate DCT i20s, with their 121g/km ratings, falling into the 29 per cent segment. All figures remain unchanged through the 2022/23 tax year.

Insurance groups

Insurance premiums shouldn't prove to be too expensive with entry-level SE Connect cars placed in group 12. Higher-spec i20 Premium and Ultimate versions will cost a little more as they are ranked in group 14 and 15 respectively. In comparison, base Renault Clio models start from group 10.

Depreciation

Specific residual value data isn't yet available for the i20. The previous generation i20 model retained around 37-39% over a typical three-year/36,000-mile ownership period, so the boxfresh third-gen model should prove to be a slightly stronger bet. Again, by way of comparison, the Renault Clio manages to hold onto around 42-46% of its original value after the first three years.
