What are Front-Wheel Drive and Rear-Wheel Drive Vehicles?
1 Answers
"Front-wheel drive vehicles connect the engine to the transmission, which then directly transmits power to the front wheels via two drive shafts. In contrast, rear-wheel drive vehicles are powered by the rear wheels. Depending on the engine's position, rear-wheel drive can be further categorized into front-engine rear-wheel drive, mid-engine rear-wheel drive, and rear-engine rear-wheel drive. Simply put, the structural difference between the two is that front-wheel drive vehicles pull the car, while rear-wheel drive vehicles push it. The engine difference between front-wheel and rear-wheel drive vehicles lies in the fact that rear-wheel drive vehicles typically use longitudinally mounted engines, which occupy significant rear cabin space and increase the vehicle's weight. The additional drive shaft also leads to greater power loss. On the other hand, most front-wheel drive vehicles employ front-mounted engines positioned further forward, benefiting from better cooling conditions. This design helps reduce unnecessary power loss and improves fuel efficiency. Handling is a major advantage of rear-wheel drive vehicles. In front-wheel drive cars, the front wheels must simultaneously handle steering and driving, which can lead to compromised performance, especially during sharp turns where understeer (commonly known as 'pushing') often occurs. Rear-wheel drive vehicles, with their heavier rear ends, are more affected by inertia and are prone to oversteer (or 'fishtailing') on icy or snowy roads."
