Final answer:
Front wheel drive (FWD) powers the front wheels, rear wheel drive (RWD) powers the rear, and 4 wheel drive (4WD) powers all four wheels, each offering differing benefits in terms of handling, fuel efficiency, and traction.
Step-by-step explanation:
The difference between front wheel, rear wheel, and 4 wheel drive lies in the wheels that receive power from the engine. In front wheel drive (FWD), the engine sends power to the front wheels, which then pull the car forward.
Conversely, in rear wheel drive (RWD), the engine powers the rear wheels, pushing the car forward. 4 wheel drive (4WD), sometimes also known as all-wheel drive (AWD), sends power to all four wheels, providing better traction and control in varied driving conditions. The main benefit of FWD is typically better fuel efficiency and traction in slippery conditions, whereas RWD offers improved handling and performance. 4WD systems are especially beneficial in off-road or extreme weather conditions, as they can provide maximum traction and power distribution to the wheels that need it the most.
