Low figures relate to the least economical version; high to the most economical. Based on WLTP combined fuel economy for versions of this car made since September 2017 only, and typical current fuel or electricity costs.

Fuel economy

Petrol engines 27.7 - 30.7 mpg
Diesel engines 40.9 mpg
  • No hybrids, but a frugal mix of petrol and diesel engines
  • Cheap servicing and reasonable insurance
  • Plenty of dealers dotted around the country

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.

The 197hp 2.2-litre CRDi turbodiesel engine is set to be the most economical, returning a claimed average fuel economy figure of 50.4mpg. There’s then a big drop down to the 244hp 2.0-litre T-GDi turbocharged petrol engine, claiming an average fuel economy of 35.8mpg.

Finally, the least-economical engine is, unsurprisingly, the top-of-the-range 365hp 3.3-litre T-GDi V6, managing a claimed 28.5mpg on average.

The Kia Stinger’s emission levels are unremarkable, with even the least-powerful 2.2-litre CRDi diesel engine producing 147g/km of CO2. As for the petrols, the 2.0-litre T-GDi unit emits 181g/km of CO2, while the 3.3-litre T-GDi rates poorly at 225g/km – more than a Porsche 911 Turbo…

A hybrid or electric version has not yet been confirmed, however given Kia’s use of the technology in the Niro, Soul and Optima models, don’t be surprised to see a part- or fully-electric version later down the line.

  • 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.

For those looking for the best reliability, the 2.2-litre CRDi diesel and 2.0-litre T-GDI petrol have been extensively used on other Kia models in the UK – the 3.3-litre T-GDi V6 is an all-new engine.
