4WD on a car stands for four-wheel drive, which distributes the engine's output torque to the wheels in varying proportions based on road conditions to achieve better handling and traction. Types of four-wheel drive systems: 1. Full-time 4WD: The vehicle is always driven by all four wheels independently; 2. Part-time 4WD: The driver manually switches between two-wheel drive and four-wheel drive modes via a transfer case based on road conditions; 3. On-demand 4WD: The system automatically switches between two-wheel drive and four-wheel drive depending on driving conditions, engaging four-wheel drive when necessary while remaining in two-wheel drive otherwise.

What is the fuel tank capacity of the Toyota RAV4?

RAV4 Rong Fang-2021 2.0L CVT Two-Wheel Drive Urban Edition has a fuel tank capacity of 55L. The engine is a 2.0L naturally aspirated engine, and the transmission is a 10-speed continuously variable transmission (CVT). The drive type is front-engine, front-wheel drive. The front suspension type is MacPherson independent suspension, and the rear suspension type is E-type multi-link independent suspension. Among vehicles in the same class, the Honda CR-V-2021 240TURBO Manual Two-Wheel Drive Classic has a fuel tank capacity of 53L, and the Wildlander-2022 2.0L CVT Two-Wheel Drive Leading Edition has a fuel tank capacity of 55L. During actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity marked by the car manufacturer is from the bottom of the tank to the safe limit, and there is still some space from the safe limit to the tank opening. This space ensures that the fuel in the tank can expand when the temperature rises without overflowing the tank's safe space. If fuel is added up to the tank opening during refueling, the actual refueling amount may be larger than the calibrated fuel tank capacity. If the owner wants to know the remaining fuel in the tank, they can observe the fuel gauge on the right side of the dashboard, which is marked with E and F. When the pointer is close to E, it means the fuel is almost empty, and when it is close to F, it means the fuel is sufficient.
