Summary
Drivetrains transfer power from the engine to the wheels.
Gears, transmissions, drive shafts, and differentials are used to transmit the power.
Vehicles can be front-, rear-, four-, or all-wheel drive.
All-wheel drive vehicles have become popular because they have superior traction on all types of road conditions.
