  • The most common layout for a rear-wheel-drive car with the engine and transmission at the front of the car is mounted longitudinally. Other layouts of rear-wheel-drive cars include front mid-engine, rear mid-engine, and rear engine.
  • A few cars have a rear-mounted engine and rear-wheel drive. The rear wheels are independently suspended. However, the wheels and the outboard CV joints do not turn through wide angles for steering. Some of these cars have plunging CV joints at both ends of each half shaft. The rear-drive axle is often suspended from the body or frame of the vehicle by leaf springs attached to the axle housing.  

The rear-drive axle uses hypoid gears. Hyoid gears have teeth cut is a spiral form, with the pinion gearset below the centerline of the ring gear. This lowers the driveshaft, which allows a lower floor pan and driveshaft tunnel. It also allows more teeth to be in contact to carry the load.
