The Genesis G4KE is a 3,342 cc, 60-degree V6 petrol engine produced between 2016 and 2020. It features dual overhead camshafts (DOHC), gasoline direct injection (GDI), and continuously variable valve timing (CVVT) on both intake and exhaust camshafts. In standard form, it delivered 270 kW (365 PS) and 510 Nm of torque, providing strong, linear power delivery for effortless acceleration.
Fitted primarily to the first-generation Genesis G80 and G90 sedans, the G4KE was engineered for refined, powerful performance with a focus on smoothness and quiet operation. Emissions compliance was achieved through GDI and precise valve timing control, allowing it to meet Euro 6 standards across its production run.
One documented concern is potential carbon buildup on intake valves, a known characteristic of direct-injection engines without auxiliary port injection. This issue, addressed in Genesis Service Bulletin TSB-17-FL-003, can lead to rough idle or hesitation if not managed. Regular induction cleaning is recommended as preventative maintenance.

The naturally aspirated V6 provides linear, predictable power ideal for relaxed cruising but requires periodic induction cleaning (every 40,000-60,000 km) to mitigate carbon buildup on intake valves inherent to GDI systems. Genesis Genuine 5W-30 oil is critical for optimal engine protection and variable valve timing operation. While timing chains are designed for longevity, adhering to scheduled maintenance is paramount. Fuel economy is moderate for its class; using 95 RON fuel is recommended for optimal performance and emissions control.
Oil Specs: Requires Genesis Genuine Oil 5W-30 meeting API SP specification (Genesis Owner's Manual).
Emissions: Euro 6 certification applies to all 2016-2020 models (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under SAE J1349 standards. Output is consistent across model years (Genesis TIS Doc. G4KE-010).

The Genesis G4KE was used exclusively in Genesis's flagship G80 and G90 sedans with longitudinal mounting. This engine received minor ECU calibrations for different model years but no major mechanical revisions affecting core compatibility during its 2016-2020 production. All adaptations are documented in OEM technical bulletins.
Locate the engine code 'G4KE' stamped on the front of the left cylinder head, near the timing cover (Genesis TIS G4KE-002). The 8th digit of the VIN is 'L' for G80 3.3L and 'K' for G90 3.3L models. The engine features a distinctive black plastic intake manifold with '3.3 GDi' lettering. Differentiation from the turbocharged Lambda II 3.3T (G4KJ) is clear: G4KE is naturally aspirated with no visible turbochargers or intercoolers. Service parts are generally consistent across 2016-2020 model years for this engine variant.
The G4KE's primary reliability consideration is intake valve carbon buildup, a common trait of direct-injection engines. Genesis service data indicates this is manageable with preventative maintenance, while UK DVSA records show no significant pattern of related MOT failures. Extended oil change intervals or consistent short-trip driving can accelerate deposit formation, making adherence to the maintenance schedule critical.
Analysis derived from Genesis technical bulletins (2016-2020) and UK DVSA failure statistics (2018-2023). Repair procedures should follow manufacturer guidelines.
