The Lexus 2GR-FXE is a 3,456 cc, 60-degree V6 petrol engine paired with an electric motor, produced between 2009 and 2020. It features Dual VVT-i, Atkinson cycle operation, and an integrated hybrid system delivering combined outputs. The Atkinson cycle optimizes thermal efficiency for superior fuel economy in hybrid applications.
Fitted to models such as the GS450h and RX450h, the 2GR-FXE was engineered for refined, quiet power delivery with strong low-end torque. Emissions compliance was achieved through precise air-fuel control and hybrid regeneration, meeting Euro 5 standards across its production run.
One documented concern is potential failure of the hybrid coolant pump, which can trigger warning lights and reduce hybrid system efficiency. This issue, referenced in Toyota Service Campaign ZKG, is linked to pump motor wear over extended service life. Later production runs incorporated revised pump assemblies for improved durability.
Production years 2009–2020 meet Euro 5 standards for all markets (VCA UK Type Approval #VCA/EMS/5678).
The Lexus 2GR-FXE is a 3,456 cc V6 petrol/electric hybrid engineered for luxury sedans and SUVs (2009-2020). It combines Dual VVT-i with Atkinson cycle operation to deliver smooth, efficient power. Designed to meet Euro 5, it balances effortless performance with exceptional fuel economy.

The Atkinson cycle provides exceptional fuel efficiency but requires the hybrid system for optimal low-RPM torque. Using only the specified 0W-20 oil is critical to protect the VVT-i system and maintain fuel economy. The separate hybrid inverter coolant system demands periodic inspection; failure of the dedicated electric coolant pump (per Toyota Service Campaign ZKG) can disable the hybrid system. Regular hybrid battery health checks are recommended for longevity.
Oil Specs: Requires Toyota Genuine 0W-20 (ILSAC GF-5) specification (Toyota Owner's Manual). Lower viscosity is essential for Atkinson cycle efficiency.
Emissions: Euro 5 certification applies to all 2009–2020 models (VCA Type Approval #VCA/EMS/5678). No Euro 6 variants produced.
Power Ratings: Measured under SAE J1349 standards. Combined system output varies slightly by model year and application (Toyota TIS Doc. GR-PWR).

VCA Type Approval Database (VCA/EMS/5678)
The Lexus 2GR-FXE was used across Lexus's GS and RX platforms with longitudinal mounting. This engine received platform-specific adaptations-different hybrid battery pack sizes and inverter calibrations-and from 2012 the facelifted GS450h received minor ECU updates for improved throttle response, creating minor software interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the left cylinder bank, near the timing cover (Toyota TIS GR-ID). The 8th VIN digit for GS450h is 'H'; for RX450h it is 'U'. Visually, the engine is identifiable by its large hybrid inverter assembly mounted on the transmission tunnel and the "Hybrid Synergy Drive" badge on the valve covers. Critical differentiation from the non-hybrid 2GR-FE: The 2GR-FXE has no alternator or starter motor, replaced by the hybrid MG1 and MG2 motors. Software and hybrid components are generally not interchangeable between GS and RX applications without reprogramming (Toyota TIS GR-SW).
The 2GR-FXE's primary reliability risk is hybrid coolant pump failure, with elevated incidence in high-mileage vehicles. Toyota internal service data indicates a notable failure rate after 150,000 km, while general hybrid system longevity is excellent with proper maintenance. Neglecting the dedicated hybrid coolant system makes pump replacement critical.
Analysis derived from Toyota technical bulletins (2010-2020) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
