Hyundai i30 review - MPG, CO2 and running costs

There’s no dedicated i30 eco model, but all versions should return decent fuel economy

All Hyundai i30 models return reasonable fuel economy, though if rock-bottom running costs are a priority, then opt for the fleet-friendly diesel. The 1.6-litre CRDi 113bhp diesel engine will return 60.1mpg on the combined cycle, while also emitting 123g/km of CO2. 

Next best is the 118bhp 1.0-litre turbo petrol. It’s our pick of the range, feeling sprightly and agile, while also returning a decent 49.6mpg and emitting 130g/km of CO2.

The 1.4-litre turbo petrol is the least economical of the standard i30 models, emitting 143g/km of CO2 while returning 44.8mpg. 

All cars come with Hyundai’s stop-start technology, which shuts off the engine in traffic. Unfortunately, there’s no super-frugal eco model like Volkswagen has managed with the Golf BlueMotion. If you want a hybrid or electric Hyundai, you'll need to look towards the excellent Ioniq family car.

Insurance groups

The extensive list of safety kit should keep insurance prices low, while relatively modest engine outputs will ensure younger drivers can afford to run an i30 without too much trouble. Hyundai i30 insurance groups start at group 8 (for the most basic i30 1.0 in S spec) and rise to 13 for the higher-powered diesel in Premium SE guise. If you want an i30N Performance model, you'll need to prepare yourself for a bigger premium as it sits in group 28.

Depreciation

Expert data suggests the i30 will not be the best performer when it comes to residual values, with an average of just 37% saved over 3 years and 36,000 miles. The 1.0-litre T-GDI models fare a little better overall, as does the 2.0-litre N Performance version.
