The Toyota 2AR-FE is a 2.5-liter inline-four engine from Toyota’s AR engine family, designed for a balance of performance, fuel efficiency, and low emissions. It features an aluminum alloy block and head, DOHC (dual overhead camshaft) with 16 valves, and Dual VVT-i (Variable Valve Timing with intelligence) on both intake and exhaust camshafts. The engine uses sequential multi-port fuel injection and a timing chain for reduced maintenance needs. With a high compression ratio of around 10.4:1 and an efficient combustion design, the 2AR-FE produces between 169 to 180 horsepower and around 170 to 175 lb-ft of torque, depending on the application. It is known for smooth power delivery, quiet operation, and long-term reliability.

The 2AR-FE has been widely used in Toyota and Lexus mid-size vehicles since the late 2000s. Common applications include the Toyota Camry, RAV4, Highlander, Venza, Scion tC, and Lexus ES 250 (in some markets). It’s also used in hybrid variants like the 2AR-FXE, found in the Toyota Camry Hybrid and RAV4 Hybrid, which operates on the Atkinson cycle for enhanced fuel efficiency. The 2AR-FE has earned a strong reputation for its low operating costs, fuel economy, and dependability, making it a popular choice for daily drivers, family cars, and fleet vehicles around the world.
