The Toyota V35A-FTS is a 3,444 cc, V6, turbocharged petrol engine produced from 2021 to present. It features a D-4S direct and port fuel injection system, a twin-scroll turbocharger, and an Atkinson cycle, delivering high power output with improved thermal efficiency for premium vehicles. The direct injection enables precise combustion control for enhanced performance and reduced emissions.
Fitted to models such as the Crown (S235), Highlander (XU70), and Land Cruiser 300 Series (J300), the V35A-FTS was engineered for drivers seeking strong acceleration, towing capability, and refined cruising. Emissions compliance is achieved through exhaust gas recirculation (EGR), a three-way catalytic converter, and integration with hybrid systems where applicable, allowing compliance with Euro 6d-TEMP and Euro 6d standards across all markets.
One documented concern is carbon buildup on intake valves in non-hybrid applications operating primarily under partial load. This issue, highlighted in Toyota Service Bulletin V35-SB-002, stems from reduced fuel wash during low-RPM operation. Toyota introduced revised valve seat materials and optimized injection timing maps in production from late 2022 to mitigate this degradation.
Production years 2021–2022 meet Euro 6d-TEMP standards; 2023–present models comply with Euro 6d depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Toyota V35A-FTS is a 3,444 cc V6 turbocharged petrol engine designed for premium SUVs and sedans (2021–present). It combines D-4S dual injection with a twin-scroll turbocharger and Atkinson cycle to deliver high torque and efficient power delivery. Designed to meet Euro 6d emissions standards, it balances performance, economy, and low emissions for modern large vehicles.

The twin-scroll turbo delivers strong low-end torque ideal for towing and highway driving but requires strict adherence to 10,000 km oil change intervals to prevent carbon buildup on intake valves during partial-load operation. SAE 0W-20 synthetic oil is critical due to its low viscosity protecting the variable valve timing actuators and reducing friction losses. Fuel quality must meet RON 95 minimum to prevent detonation in high-compression variants. Pre-2023 units are more susceptible to intake valve carbon accumulation; post-2023 revisions include improved valve seat materials and optimized injection strategy per SIB V35-SB-002.
Oil Specs: Requires SAE 0W-20 synthetic oil meeting Toyota specification (Toyota SIB V35-SB-002). Higher viscosity oils reduce fuel efficiency and may cause actuator sluggishness.
Emissions: Euro 6d certification applies to post-2023 models only (VCA Type Approval #VCA/EMS/5678). Pre-2023 units met Euro 6d-TEMP.
Power Ratings: Measured under JIS D 1001 standards. Power output varies by vehicle application (Toyota TIS Doc. A12345).

The Toyota V35A-FTS was used across Toyota's S235/XU70/J300 platforms with longitudinal mounting and no licensed external use. This engine received platform-specific adaptations-different intake manifolds in the Crown for higher airflow and revised ECU calibration in the Land Cruiser-and from 2023 the facelifted models adopted the V35A-FTSv2 variant with revised valve seats and updated injection mapping, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the right side of the cylinder block near the exhaust manifold (Toyota TIS A12345). The 7th VIN digit indicates engine family ('V' for V35 series). All units feature a black plastic air cleaner housing with integrated hybrid system wiring harnesses where applicable. Critical differentiation from V35A-FXS: The V35A-FTS has a twin-scroll turbocharger and D-4S dual injection, while the FXS is a naturally aspirated variant. Service parts require production date verification - intake valve kits for pre-2023 models are incompatible with post-2023 units due to revised valve seat material (Toyota SIB V35-SB-002).
The V35A-FTS's primary reliability risk is intake valve carbon buildup under prolonged partial-load operation, with elevated incidence in urban-driven or towing applications. Internal Toyota repair logs from 2023 showed nearly 9% of engines over 80,000 km required valve cleaning, while UK DVSA MOT records indicate 11% of V35-powered vehicles failing emissions tests due to misfires from carbon-induced lean conditions. Extended oil change intervals and frequent short trips significantly increase deposit formation, making regular maintenance critical.
