An individual automatic transmission for each road wheel, independently connected to the drive shaft, so that each wheel acts without regard to the requirements of the other road wheels. With exception of some type of manual reversing system, a brake, and a gas pedal, no manually operated clutches, shift levers, or differential gearing is required. A vehicle having four road wheels has a correct torque exerted on each of the wheels as long as the drive engine is running, the intensity of which is determined by road conditions on that wheel and on the desires of the operator who controls the engine speed. Connection of each driven wheel shaft to the engine shaft can be made by bevel gears of the desired ratio and/or universal couplings.
