Many cars have front wheel drive. With front wheel drive, the engine power is connected to the front wheels by a transaxle The transaxle does all the things that the drive shaft and differential do in rear-wheel-drive car.

Front wheel drive makes better use of the car's inside space because it eliminates the big bump in the floor that rear-wheel-drive cars have. The bump results from the latter's drive shaft, which is needed to carry engine power to the read wheels. And because most of the car's weight is over the drive wheels, front wheel drive has better traction.
