How much does it cost to run?

Kia Stinger running costs will likely be a mixed bag. On the one hand cheap servicing should be complemented with exceptional reliability and an unrivalled seven-year warranty. However, the claimed fuel economy figures are far from class leading and could negate the savings on maintenance costs over more premium rivals.

A hybrid or electric version has not been confirmed.

  • 3.3 T-GDI: 28.0mpg, 229g/km CO2

During our time of testing we saw fuel economy hover around 24mpg when driving on short journeys around town. Motorway journeys saw this creep up to the high 20s, with scope of breaking into the low 30s on a longer cruise.

With a 60 litre tank, fuel range was approximately 320 miles, which isn’t great if you’re looking for a long-distance GT cruiser type of vehicle – even if some performance saloons don’t achieve much more than this. This range also tumbled when doing short journeys, so 300 miles might be possible.


The service intervals for the Stinger GT S are frequent, at every 6 months or 6,000 miles, whichever is sooner – that’s not much more than the highly-tuned Mitsubishi Lancer Evo IX’s 4,500 miles.

How reliable is it?

  • Standard seven-year warranty speaks volumes
  • Too soon to say for sure, but Stinger should provide excellent reliability
  • No complicated hybrid or EV components to go wrong

The standard seven-year warranty indicates that Kia Stinger reliability levels should be about as sound as the rest of the South Korean manufacturer’s range. And, although the Stinger is a brand-new model, many of the components will have been tried-and-tested on other Kia products.

There’s only been one recall in late 2020, relating to the fuel pump nozzle – and that only affected one vehicle.

There are only a few owner’s reviews on the Kia Stinger on the Parkers site, but this is hardly a surprise considering how few we see on the roads.
