3.5 out of 5

Hyundai resale values are considerably better than what they used to be, so you can expect to get a fair amount of your money back on the used-car market when the time comes to sell your i40. Good residual values will also help you secure a better finance deal if you’re buying the car that way. And if that time falls within the duration of the car’s five-year warranty, the unlimited-mileage ‘triple care’ package (including roadside assistance and free dealer health checks) goes with the car to the new owner. That’s quite a package, by anyone's standards.

Hyundai i40 MPG and CO2

The i40 is a pretty cheap car to run, combining an economical diesel engine with affordable servicing and reasonable insurance costs across the range. The 1.7-litre diesel engine comes in two different power outputs, with the less powerful version offering claimed average fuel economy of 67.3mpg and CO2 emissions of just 110g/km. The more powerful version of the same engine returns 65.7mpg and emits 114g/km of CO2, so it isn’t any more expensive to tax per year and will be only slightly pricier to fuel in the long run. This means there’s no real downside to choosing it as long as don’t midn the marginally higher price.

Insurance group

Insurance ratings for the i40 saloon range from groups 13 to 20, so cover should be quite reasonable whatever model you go for. In comparison, a top-of-the-range Peugeot 508 (which is admittedly more powerful than the i40) hits insurance group 37.


This is one area where the i40 really shines. You get five years of manufacturer cover, with no mileage limit, and the warranty can be transferred to the car’s second owner if you sell it before then. The Hyundai’s Kia Optima sister model has a seven-year warranty, but there’s a 100,000-mile limit so it’s not quite as good a deal for high-mileage motorists.


Hyundai offers three and five-year fixed-price servicing plans for the i40. For a one-off payment of £499 or £799 respectively, all scheduled services are covered. The amount can be paid in full up front, or incorporated into your finance payment.
