VEHICLE LAYOUT II

Rear wheel drive

Rear-wheel drive (RWD) is a vehicle layout where power is delivered to the rear wheels, which are responsible for propulsion, while the front wheels are primarily for steering. In this configuration, the engine is typically positioned longitudinally (front to back) in the front of the vehicle, with the transmission located behind it.

Advantages of Rear-Wheel Drive

  1. Balanced handling: RWD vehicles tend to exhibit better balance and weight distribution compared to front-wheel drive counterparts, resulting in more neutral handling characteristics.
  2. Enhanced performance: RWD vehicles often provide better acceleration and cornering capabilities, particularly in high-performance and sports car applications, due to the rear wheels driving the vehicle and the front wheels being free to focus solely on steering.
  3. Towing capability: RWD vehicles generally have higher towing capacities compared to front-wheel drive counterparts, as the weight distribution allows for better stability when towing heavy loads.
  4. Durability: The drivetrain components of RWD vehicles are typically more robust and durable, as they are designed to withstand the higher torque and stress levels associated with rear-wheel drive systems.

Disadvantages of Rear-Wheel Drive

  1. Limited traction: RWD vehicles may struggle with traction in slippery conditions such as rain, snow, or icy roads, especially if they are not equipped with traction control or limited-slip differentials.
  2. Reduced interior space: The drivetrain layout of RWD vehicles often results in a tunnel running through the center of the vehicle, limiting interior space and potentially compromising passenger comfort.
  3. Higher manufacturing costs: The design and engineering required for RWD vehicles can be more complex and costly compared to front-wheel drive counterparts, which may translate to higher purchase prices for consumers.
  4. Handling challenges in adverse conditions: RWD vehicles can be more challenging to control in adverse conditions such as heavy rain or snow, as the rear wheels are prone to losing traction and causing oversteer, where the rear of the vehicle slides out.

EVALUATION: 1.  What is rear wheel drive?

  1. Mention 4 advantages of rear wheel drive
  2. State 4 disadvantages of rear wheel drive
