MPG, running costs & CO2 Rating

4.0 out of 5

Choosing a car like the Hyundai i30 N rather than a diesel supermini clearly indicates you’re more interested in performance than economy, but a good hot hatch should be able to be used as a family car, capable of covering decent mileage without frequent and costly pit stops.

Hyundai i30 N MPG & CO2

The i30 N doesn’t fall down in this regard, with economy officially pegged at 34.9mpg for the standard model and 34mpg for the 271bhp version. This places the 247bhp i30 N roughly on a par with the petrol-engined Ford Focus ST that has an official 34.4mpg figure.

With CO2 emissions of 185g/km for the 247bhp i30 N and 188g/km for an i30 N Performance, you’ll be liable for the highest Benefit-in-Kind rate of 37% if you want either as a company car. The i30 N will cost £150 a year in VED road tax and consumable items such as tyres and brake pads and discs will be more costly than those fitted to a regular i30.

Insurance group

The Hyundai i30 N sits in insurance group 27 out of 50, while the N Performance version is only one group higher. The Golf GTI sits in group 29 and hot hatchbacks tend to attract relatively high premiums – although we’re not talking supercar money here.


Hyundai offers one of the best warranties in the business, with a five-year/unlimited-mileage guarantee.


Hyundai’s fixed-price service plans run from two to five years in duration, and cost between £250 and around £1,200 depending on the length of the policy you take out and the model you take it out on. As this is a performance car from a brand-new performance subdivision, it’s possible Hyundai will design a unique service plan for the i30 N – but this should still be relatively affordable.
