The Kia Stinger (Generation I - CK) is a grand touring sedan (fastback) that marked a major turning point for the Korean manufacturer. Developed under the leadership of Albert Biermann (former head of BMW M), it is based on a rear-wheel drive (or AWD) architecture shared with the Genesis G70. Designed to compete with the German benchmarks (Audi A5 Sportback, BMW 4 Series Gran Coupé), it offers top-flight dynamic behavior, a plethora of equipment, and an unbeatable price-to-performance ratio. Although its production continued until 2023 with a slight facelift at the end of 2020, the 2018-2021 period covers the core of its career. It is an enthusiast's vehicle, generally reliable, but which requires rigorous maintenance, particularly on its turbocharged engines.
The Kia Stinger is a formidable driving machine that proved Kia could compete with the German premium brands on their own turf. The verdict is clear: favor the 3.3 T-GDI V6. It is the engine that best matches the Grand Touring spirit of the car, and paradoxically, it is also the most reliable in the long term, provided the turbo oil pipe recall has been performed. The 2.0 T-GDI (Theta II) should be approached with more caution due to its mixed reliability history at Hyundai/Kia. Scrupulously check the maintenance history, the condition of the brakes (vibrations), and take advantage of depreciation that makes it one of the best deals on the used market for enthusiasts.
