The Kia Stinger GTS is powered by a 3,342 cc, twin-turbocharged V6 petrol engine produced between 2019 and 2023. It features gasoline direct injection (GDi), twin-scroll turbochargers, and dual continuously variable valve timing (CVVT). This engine was designed to offer exhilarating performance, delivering 272 kW (370 PS) and 510 Nm of torque, making it Kia's most powerful production engine at launch.
Exclusively fitted to the rear-wheel-drive Stinger GTS (CK), this engine was engineered for drivers seeking sports car-like acceleration and handling dynamics. Emissions compliance was achieved through a sophisticated three-way catalytic converter system and upstream/downstream oxygen sensors, allowing it to meet stringent Euro 6d-TEMP standards across its production run.
One documented reliability concern involves premature wear of the high-pressure fuel pump, which can lead to reduced fuel pressure and engine misfires under high load. This issue, referenced in Kia Technical Service Bulletin TSB-21-GAS-008, is often linked to fuel quality or extended service intervals. Kia later revised the pump's internal components and updated diagnostic software to better detect early failure modes.
All production years 2019–2023 meet Euro 6d-TEMP standards (VCA UK Type Approval #VCA/EMS/9876).
The Kia Stinger GTS engine is a 3,342 cc V6 twin-turbo petrol engineered for high-performance GT applications (2019-2023). It combines direct injection with twin twin-scroll turbochargers to deliver explosive acceleration and sustained high-RPM power. Designed to meet Euro 6d-TEMP standards, it balances raw performance with regulatory compliance.

The twin-turbo setup provides explosive, lag-free power ideal for overtaking but demands strict adherence to 10,000 km or annual oil change intervals to protect the turbos and timing chains. ACEA C3 (5W-40) oil is critical to handle high thermal loads and prevent turbo bearing wear. The engine is highly sensitive to fuel quality; only premium unleaded (RON 98) should be used for optimal performance and to prevent knocking. Vehicles used for frequent track driving may require more frequent inspection of intercooler hoses and turbo actuators.
Oil Specs: Requires ACEA C3 specification oil (Kia Owner's Manual OM-GTS-2019).
Emissions: Euro 6d-TEMP certification applies to all 2019–2023 models (VCA Type Approval #VCA/EMS/9876).
Power Ratings: Measured under SAE J1349 standards. Peak output requires RON 98 fuel (Kia TSB 22-PER-001).

The Kia Stinger GTS engine was used exclusively in the Kia Stinger (CK) platform with longitudinal, rear-wheel-drive mounting. This engine received no platform-specific adaptations during its production run, as it was a bespoke performance variant. The GTS trim featured unique engine tuning and cooling enhancements, but the core engine block and major components remained consistent with the standard 3.3L V6. All specifications are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the cylinder block, near the crankshaft pulley (Kia Workshop Manual WM-GTS-01). The 8th digit of the VIN is 'G' for the GTS variant. Visually, the engine is identifiable by its unique red valve covers, twin turbochargers with red inlet pipes, and the “GTS” badge on the strut tower brace. Critical differentiation from the standard 3.3L V6: The GTS uses a higher-capacity intercooler, revised ECU mapping, and a sport-tuned exhaust system. While many internal components are shared, the tuning and some ancillary parts are specific to the GTS.
The Stinger GTS's primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles using poor-quality fuel or exceeding service intervals. Kia TSB 21-GAS-008 notes a cluster of pump failures before 80,000 km under these conditions, while DVSA data indicates turbocharger actuator faults are a common cause of boost-related warning lights. Neglecting oil changes and using low-grade fuel make preventative maintenance critical.
