Hyundai i20 review - MPG, CO2 and running costs

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

The i20's 1.0-litre petrol engine is respectably frugal – and indeed, nearly identically frugal regardless of whether you opt for the iMT 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.

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. 

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.

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

The previous generation i20 model retained around 37-39 per cent over a typical three-year/36,000-mile ownership period, while the third-gen model is a stronger bet, holding onto 51-54 per cent. The sporty N Line versions are the best performers, although the standalone N model is predicted to be worth 59 per cent of its original value after 36 months of driving.
