All You Need To Know About Rear Wheel Drive

RWD stands for Rear Wheel Drive. In rear wheel drive, the power from the engine is delivered only to the rear wheels of the vehicle. That means the rear wheels are pushing the car and the front wheels don’t receive any power from the vehicle.

Several components such as driveshaft, also known as propeller shaft and differential are used to provide RWD (Rear Wheel Drive).

Due to the weight of an RWD vehicle being more evenly spread than an FWD vehicle, it creates a better balance of weight.

Most of the sports cars such as the Corvette and Camaro are RWD and are more exciting to drive.

How does it work?

RWD

A longitudinally mounted engine, with the directly bolted transmission, sends power via a driveshaft to a differential unit at the rear axle. The differential turns the power 90° and sends it to the rear wheels. (Some sports cars such as Corvettes, Ferraris and Porsches place a combined transmission and differential or transaxle in the rear.)

The driveshaft connects via yoke type universal joints and a splined expansion joint to allow for vertical and longitudinal suspension movement.

Possible Configurations

According to the position of engine and gearbox, RWD (Rear Wheel Drive) layout can have the following arrangements:

  • Front-mounted engine with rear-wheel drive
  • Mid-mounted engine with rear-wheel drive
  • Rear-mounted engine with rear-wheel drive

Pros:

Pros of a vehicle with RWD are reasonable enough to like them.

  •  Simple in design and configurations.
  • A vehicle with RWD can give you the best ride of your life, due to its high-end performance.
  • Rear-wheel drive tends to have less costly maintenance as there aren’t so many parts packed into a small space.
  • You won’t experience “torque steer”.
  • Pro drivers and enthusiasts prefer RWDs.

Cons:

  • Can’t perform well in bad weather conditions
  • RWD vehicles are more prone to loss of traction on slick roads.
  • Compared to other drivetrain vehicles, RWD drive system vehicles are not the cheapest one.
