The Lexus V35A-FTS is a 3,497 cc, twin-turbocharged V6 petrol engine produced between 2018 and the present. It features direct fuel injection, dual overhead camshafts, and variable valve timing with intelligence (VVT-iW) on the intake side, delivering strong power and torque for performance-oriented vehicles. The integrated exhaust manifold design reduces warm-up time and improves thermal efficiency for enhanced everyday drivability.
Fitted to models such as the LC 500, LS 500, and GS 350, the V35A-FTS was engineered for refined high-speed cruising, smooth power delivery, and responsive acceleration. Emissions compliance was achieved through advanced three-way catalytic converters and precise air-fuel ratio control, allowing all models to meet Euro 6d-TEMP and Euro 6d standards depending on market.
One documented concern is carbon buildup on intake valves, which can lead to misfires and reduced performance over time. This issue, highlighted in Lexus Technical Service Bulletin TSB-LX-001-2020, stems from the direct injection system’s lack of fuel wash on the valve surfaces. Lexus introduced revised intake port designs and updated ECU calibration in later production units to mitigate accumulation.
Production years 2018–2020 meet Euro 6d-TEMP standards; 2021–present models meet Euro 6d depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Lexus V35A-FTS is a 3,497 cc twin-turbocharged V6 petrol engine engineered for luxury performance sedans and coupes (2018–present). It combines direct fuel injection with variable valve timing on the intake side to deliver high specific output and smooth responsiveness. Designed to meet Euro 6d-TEMP and Euro 6d emissions standards, it balances dynamic performance with improved efficiency.

The twin-turbo V6 delivers rapid throttle response and high torque across a broad rev range, ideal for highway overtaking and spirited driving, but requires strict adherence to 10,000 km oil change intervals using 0W-20 synthetic oil to prevent carbon buildup on intake valves. Direct injection eliminates fuel wash, making periodic induction cleaning recommended. Use of premium unleaded fuel (RON 95 or higher) is critical to avoid knock under load. Oil consumption beyond 0.1 L/1,000 km may indicate valve seal wear and should be investigated per Lexus SIB LX-001-2020. Post-2020 revisions include modified intake port geometry to reduce deposit formation.
Oil Specs: Requires Lexus Genuine 0W-20 (API SN+ / ILSAC GF-6) specification (Lexus SIB LX-001-2020). Supersedes ACEA C2 requirements.
Emissions: Euro 6d-TEMP certification applies to 2018–2020 models only (VCA Type Approval #VCA/EMS/5678). Euro 6d applies to 2021–present models.
Power Ratings: Measured under SAE J1349 standards. Maximum output (310 kW) requires RON 98 fuel quality (Lexus TIS Doc. A39015).

The Lexus V35A-FTS was used across Lexus's LC/LS platforms with longitudinal mounting and licensed to Toyota for transverse applications in European markets. This engine received platform-specific adaptations-revised intake manifolds in the LC 500 and upgraded cooling circuits in the LS 500-and from 2021 the facelifted GS 350 adopted the V35A-FTS-T variant with revised ECU mapping, creating interchange limits. Partnerships allowed Toyota's 3.5L GT-Four units to leverage Lexus's twin-turbo architecture. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front right cylinder bank near the timing cover (Lexus TIS A39102). The 7th VIN digit indicates engine family ('K' for V35 series). Pre-2021 models have silver valve covers with black plastic cam covers; post-2021 units use matte-black valve covers. Critical differentiation from 2GR-FKS: V35A-FTS has two distinct turbocharger housings mounted on the exhaust manifold, while 2GR-FKS uses a single turbo. Service parts require production date verification - intake components for pre-2021 models are incompatible with later variants due to revised port geometry (Lexus SIB LX-001-2020).
The V35A-FTS's primary reliability risk is intake valve carbon buildup, with elevated incidence in urban stop-start driving. Internal Lexus data from 2021 reported a notable share of pre-2021 engines exhibiting misfire codes before 80,000 km, while UK DVSA records link over 15% of emissions-related MOT failures to restricted airflow from intake deposits. Extended idling and short-trip operation accelerate deposit formation, making regular induction cleaning critical.
