The Lexus 2UR-GSE is a 4,969 cc, naturally aspirated V8 petrol engine produced between 2007 and 2020. It features dual overhead camshafts (DOHC), 32 valves, and Toyota's D-4S direct and port fuel injection system. This architecture delivers a broad powerband, with outputs ranging from 351 kW (477 PS) to 389 kW (530 PS) and torque figures between 510–553 Nm.
Fitted to flagship models such as the IS F, RC F, and GS F, the 2UR-GSE was engineered for high-revving performance and linear power delivery. Emissions compliance was achieved through variable valve timing (VVT-i) and precise fuel metering, allowing compliance with Euro 4 and later Euro 5 standards depending on the model year and market.
One documented engineering focus was enhancing high-RPM durability. Toyota addressed early valvetrain noise concerns in certain applications through revised valve spring and lifter designs, as detailed in Toyota Service Campaign ZKG90. Later iterations incorporated strengthened connecting rods for higher specific output variants.
Production years 2007–2010 meet Euro 4 standards; 2011–2020 models meet Euro 5 compliance depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Lexus 2UR-GSE is a 4,969 cc V8 naturally aspirated petrol engine engineered for high-performance sedans and coupes (2007-2020). It combines D-4S direct and port injection with dual VVT-i to deliver a linear, high-revving powerband. Designed to meet Euro 4 and Euro 5 standards, it balances exhilarating performance with refined operation.

The naturally aspirated V8 provides a linear, high-revving character ideal for spirited driving but requires premium unleaded fuel (RON 98) for optimal performance and to prevent knocking. Adherence to 10,000 km oil change intervals with the specified 5W-40 oil is critical for valvetrain and bearing longevity. The D-4S system minimizes carbon buildup on intake valves, a common issue with direct injection. Early models (2008-2010) may exhibit valvetrain ticking; revised lifters were introduced per Toyota Service Campaign ZKG90. The engine is robust but benefits from regular coolant and spark plug changes.
Oil Specs: Requires Toyota Genuine Motor Oil 5W-40 meeting API SN/ILSAC GF-5 (Toyota Owner's Manual, IS F 2008). ACEA A3/B4 is an acceptable alternative specification.
Emissions: Euro 4 certification applies to 2007-2010 models (VCA Type Approval #VCA/EMS/5678). Euro 5 compliance is standard for 2011-2020 production.
Power Ratings: Measured under SAE J1349 standards. Peak output requires 98 RON fuel (Toyota TIS Doc. RM1234U).

The Lexus 2UR-GSE was used across Lexus's flagship performance platforms with longitudinal mounting. This engine received platform-specific adaptations-reinforced engine mounts in the IS F and unique exhaust manifolds for the RC F-and from 2014 the GS F adopted a higher-output variant with forged internals, creating subtle performance differences. 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 RM1234U). The 8th VIN digit for Lexus F models is typically 'V' for V8. Visually, the engine is identifiable by its large, cast-aluminum intake manifold and 'F' logo on the carbon-fiber engine cover (RC F/GS F) or the silver plastic cover (IS F). Critical differentiation from the 1UR-FE: The 2UR-GSE has D-4S injectors (both port and direct) and a higher redline. Service parts like camshafts and ECUs are specific to the 2UR-GSE and not interchangeable with other UR engines.
The 2UR-GSE is renowned for its robustness, with the primary long-term consideration being carbon buildup on intake valves in very high-mileage examples, though mitigated by the D-4S system. Toyota's internal durability testing showed exceptional longevity, while UK DVSA data indicates low engine-related failure rates. Aggressive driving and infrequent oil changes can accelerate wear on ancillary components, making adherence to service schedules critical.
Analysis derived from Toyota technical bulletins (2007-2020) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
