Rear-Wheel Drive advantages and disadvantages

Rear-Wheel Driv Advantage

Acceleration: When the acceleration is started, the weight of the car is transmitted backwards, thus increasing the pressure of the rear wheels, so that the rear wheels get more grip and improve the acceleration.

Easy to maintain: Unlike a front-wheel drive, all powertrain components are concentrated in the front of the car, making it mechanically simpler than front-wheel drive. Therefore, it is easier to disassemble and maintain.

Torque Steering: There is no bias problem that may result from uneven front wheel torque distribution.

Weight distribution: The rear-wheel drive car's engine and gearbox can be mounted behind the front-wheel drive. This way the weight of the car is more evenly distributed between the front and rear wheels. This will help improve the handling of the car.

Turning radius: Due to the relatively simplified transmission structure of the front wheels, the front wheels can often be rotated by a larger angle. This way, rear-wheel drive vehicles usually have smaller turning radii.

Drag force: In the case of a trailer, the rear wheel drive is closer to the trailer's attachment point for better steering performance and drag.

Rear-Wheel Driv Disadvantages

Maneuverability: Compared with front-wheel drive, rear-wheel drive vehicles are prone to over-steering, which is difficult for people with general driving skills to control.

Internal space: For the sedan, the space of the front passenger is compressed because the rear-wheel drive vehicle's engine and gearbox are positioned rearward. Since there is a drive shaft leading to the rear wheel, the floor below the rear seat must be raised. It is also possible to reduce the volume of the trunk.

Car weight: Although the mechanical design of the rear wheel drive is simpler, the components are more distributed and the total weight of the power system increases.

Price: Since the power system cannot be self-contained like the front-wheel drive vehicle during assembly, it is inferior in work efficiency, thus increasing assembly costs. In addition, the power system material costs are also more. Therefore, the general rear-wheel drive vehicle is slightly more expensive than the front-wheel drive vehicle of the same class.
