3.0 out of 5

Designed to be Kia's flagship performance car, the Stinger comes with relatively large and powerful engines, which has implications for running costs. The most economical choice is the 2.2-litre diesel but even this can only manage up to 40.9mpg, with CO2 emissions of 179g/km placing it in the highest Benefit-in-Kind (BiK) band for company-car drivers.

The 2.0-litre petrol model returns up to 30.7mpg and CO2 emissions of 209g/km, while the range-topping 3.3-litre V6 petrol just manages 27mpg with CO2 emissions of 233g/km. That’s quite some way off the Audi S5’s claimed economy of 40.9mpg, and the gap has only increased now Audi has put a potent diesel engine in the latest S5.

Tax is a flat £150 for the Stinger, with the exception of the GT-S, which incurs a surcharge of £325 from years two to six of ownership because it costs more than £40,000. Beware that if you spend enough on optional equipment on the other versions to tip the price over £40k, the same surcharge will apply, bringing your tax bill to £475 a year for the period mentioned.

Insurance group

Insurance is another area that contributes to the Stinger having among the highest running costs of any Kia. The entry-level 2.0-litre petrol starts in group 36, which is higher than the equivalent Audi A5's group 33. The flagship 3.3-litre GT-S sits in insurance group 42 out of 50.


One area in which the Stinger gets the better of its rivals, though, is warranty coverage. Kia’s seven-year/100,000-miles of cover is one of the best available, eclipsing the three-year/60,000-mile and three-year/unlimited-mileage warranties offered by Audi and BMW respectively.


Kia servicing costs are likely to be less than those of the traditional ‘upmarket’ brands, too. We expect the two petrol Stinger models to need a service every 10,000 miles or 12 months, with the 2.2-litre diesel requiring attention every 20,000 miles or 12 months.

Fixed-price servicing is available in the form of Kia’s ‘Care-3’ and ‘Care-3 Plus’ packages, which last for three and five years respectively. Expect the Care-3 pack to cost around £300 and the Care-3 Plus around £600. These schemes are also transferable to the new owner if you sell the car.
