The scene-stealing 2018 Kia Stinger sure is a shock to the industry system. Riffing on the GT concept, this super powerful fastback sport sedan is absolutely unlike anything this carmaker has ever produced before, and growling beneath that gorgeous prowling bodywork is a choice of a 2.0-liter turbocharged four-pot with around 190kW and 353Nm, or a 3.3-liter twin-turbo V6 developing an estimated 272kW and 510Nm—mated to a sole eight-speed automatic transmission.
