Hyundai i30 hatchback - MPG, running costs & CO2

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 now only available with a choice of smaller petrol engines 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 1.5-litre petrol – manages 44.8mpg in manual form and 46.3mpg with the seven-speed auto, while the turbocharged 1.0-litre petrol officially returns up to 54.3mpg. Both now come with mild-hybrid technology, essentially an advanced stop-start system that saves some fuel by using stored electrical energy.

16

When it was available, the diesel engine was the most economical on offer, but because it cost nearly £1,800 more to buy when new, it was only really suited to very high-mileage drivers. The 134bhp model returned 58.9mpg, whether you chose the manual or automatic gearbox.

After the first year's CO2-based road tax (generally included in the on-the-road price), all Hyundai i30s are subject to the standard annual tax rate. Company-car drivers will find 1.0-litre petrol i30 models to be the cheapest in terms of Benefit-in-kind (BiK) tax.

Every petrol-powered i30 equipped with mild-hybrid electrical assistance will cost the discounted VED rate (road tax) from the second year onwards.

Insurance group

The 1.0-litre i30 starts in group 10 out of 50, so it should be affordable to insure. Premium trim is a little more with a group 11 rating, while the more powerful 1.5-litre car sits in group 15 with the dual-clutch auto, and group 16 if you opt for the manual.

Servicing

Fixed-price Hyundai Sense service packages mean budgeting for maintenance will be easy. Three years’ worth of services for a petrol model comes in at around £550. Hyundai also offers fixed-price servicing for cars outside of its five-year warranty.

Warranty

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.
