MPG, running costs & CO2 Rating

4.0 out of 5

Running costs are a crucial concern for most car buyers, and family hatchbacks must be economical and cheap to maintain if they’re to have mass appeal. It’s no surprise, therefore, that the latest Hyundai i30 is available with engines – both petrol and diesel – that offer good economy; similarly, Hyundai’s fixed-price servicing deals are well priced, while the standard warranty is excellent.

Hyundai i30 MPG & CO2

Even the least efficient engine offered with i30 – the turbocharged 1.4-litre petrol – manages 46.3mpg, while the turbocharged 1.0-litre petrol officially returns 45.6mpg.

The diesel engine is even more economical, so could be worth going for if you spend lots of time on the motorway. The 113bhp model gets 58.9mpg with a manual gearbox, while the automatic version does 60.1mpg.

After the first year's CO2-based road tax (generally included in the on-the-road price), all Hyundai i30s cost £145 a year to tax. Company-car drivers will find i30 models fit in towards the lower end of the Benefit-in-kind (BiK)rating on all models except for the i30 N.

Insurance group

The 1.0-litre i30 starts in group eight out of 50, so it should be affordable to insure. The diesel sits in groups 10 to 12, while the 1.4-litre petrol is in groups 14 and 15.


Fixed-price Hyundai Sense service packages mean budgeting for maintenance will be easy. Three years’ worth of services for a petrol model is likely to come in at £550, with diesel i30s being roughly £150 more expensive.


The i30 benefits from Hyundai’s excellent five-year/unlimited-mileage warranty, which is fully transferable to secondhand buyers. This is one of the most generous in the industry, with only Kia’s seven-year warranty lasting for longer.
