Toyota 1AR-FE (2.7L Inline 4-Cylinder Gasoline Engine)
The 1AR-FE is a 2.7L naturally aspirated engine in Toyota's AR series, put into production in 2008. It emphasizes smoothness, durability, high torque, and high reliability, and is suitable for mid-size SUVs/MPVs.
Key Parameters:
Displacement: 2672cc (2.7L)
Structure: Inline 4-cylinder, DOHC 16-valve, Dual VVT-i (Variable Valve Timing)
Bore × Stroke: 90mm × 105mm
Compression Ratio: 10.0:1
Maximum Power: 182–187 hp (135–139 kW) @ 5800 rpm
Maximum Torque: 246 N·m @ 4200 rpm
Block/Cylinder Head: All-aluminum alloy (lightweight)
Timing: Single-chain (maintenance-free, long lifespan)
Fuel: 95 octane or higher gasoline
Combined Fuel Consumption: Approximately 9.9L/100km L/100km Net Weight: Approx. 139 kg Design Life: 300,000 km + (with proper maintenance) Compatible Models (2008–present) Toyota: Highlander (XU40/XU50), Sienna (XL30), Venza (GV10), Harrier Lexus: RX270 (AL10) Common Advantages and Disadvantages Advantages: Robust and durable, ample torque, smooth high-speed driving, reasonable fuel consumption, lightweight all-aluminum construction Disadvantages: Relatively loud cold start noise; water pump lifespan approximately 40,000 km; timing chain prone to stretching after 150,000 km; compression ratio may decrease at high mileage Positioning and Replacement Positioning: Replaces the older 2AZ-FE, primarily targeting the 2.7L mid-size SUV/MPV market Successor: Gradually replaced by the A25A series (2.5L hybrid/naturally aspirated).
