Rear wheel drive (RWD) refers to a specific configuration of a vehicle's drivetrain system in which power is primarily delivered to the rear wheels. In this setup, the engine sends power through a transmission located at the front of the vehicle to a driveshaft, commonly known as a propeller shaft, which connects to the differential. The differential, situated at the rear axle, is responsible for transmitting the power to each rear wheel.
The concept of rear wheel drive involves several advantages in terms of vehicle performance and handling characteristics. One of the key benefits is improved weight distribution, as the majority of the car's weight, including the engine and transmission, lies over the rear wheels. This weight distribution contributes to increased traction, especially during acceleration, and provides better stability and control, particularly in situations like cornering.
Rear wheel drive is commonly featured in high-performance vehicles, sports cars, and large luxury sedans due to its ability to handle higher levels of horsepower and torque. It also allows for better handling dynamics, as the rear wheels are responsible for both the acceleration and steering tasks, providing enhanced response and feedback to the driver.
However, rear wheel drive can have some disadvantages in certain driving conditions, such as snow or icy roads, where the rear wheels may struggle for traction due to the lack of weight over them. Nonetheless, many modern rear wheel drive vehicles are equipped with advanced traction control systems and technologies to mitigate such limitations.
Overall, rear wheel drive is a drivetrain configuration that delivers power to the rear wheels, offering advantages in terms of weight distribution, traction, and handling characteristics, particularly in performance-oriented and luxury vehicles.
