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.

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 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.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The Stinger GTS engine is robust when maintained meticulously. Its primary weakness is the high-pressure fuel pump, which can fail prematurely with poor fuel or infrequent servicing. Using premium RON 98 fuel, adhering to strict oil change intervals, and addressing boost system warnings immediately are crucial for longevity. Later production models incorporated pump revisions for improved durability.
The most frequent issues are high-pressure fuel pump failure, turbocharger wastegate/actuator faults, intercooler hose leaks, and carbon buildup on intake valves. These are well-documented in Kia service bulletins and often relate to fuel quality, maintenance neglect, or the inherent stresses of a high-performance twin-turbo engine.
The 3.3L twin-turbo V6 engine in the GTS specification was used exclusively in the Kia Stinger GTS (CK chassis) from 2019 to 2023. It was the highest-performance variant of the Stinger, featuring unique tuning, cooling, and visual enhancements over the standard 3.3L V6 model.
Yes, the engine responds exceptionally well to tuning. A Stage 1 ECU remap can safely increase power by 40-60 kW and torque by 80-100 Nm. For Stage 2+, upgrades like a downpipe, intercooler, and intake are recommended. The stock internals are strong, but aggressive tuning increases stress on the fuel pump and turbos, demanding even more rigorous maintenance.
Fuel economy is typical for a high-performance V6. Expect around 14.5 L/100km (city) and 8.5 L/100km (highway), or approximately 22 mpg UK combined. Real-world figures are heavily dependent on driving style; spirited driving will significantly reduce efficiency. The official WLTP figure is 10.2 L/100km combined.
Yes. The Stinger GTS V6 is an interference engine. If either of the timing chains were to fail or jump, the pistons would collide with the open valves, causing catastrophic internal engine damage. The chains are generally durable with proper oil maintenance.
Kia mandates a fully synthetic oil meeting ACEA C3 specifications, typically in 5W-40 viscosity. This is crucial for handling the high thermal loads of the twin-turbo engine and protecting the turbochargers. Using the correct oil and changing it every 10,000 km or annually is non-negotiable for engine health.
