Despite the time period “drivetrain” sounding like a singular factor, it is really a special grouping of parts (and there is some overlap) — the transmission, differential, driveshaft, axles, and wheels. However, one other half we have not touched on but that additionally belongs to the drivetrain is the Constant Velocity (CV) joints. These CV joints sit at every finish of the drive shaft and never solely join the wheels to the axles (and transmission) however switch torque to them as nicely. 

So, what did not we listing that we have already mentioned? The engine. The motor is part of the powertrain however not part of the drivetrain.

In essence, the drivetrain is simply part of the general powertrain, however the motor is — dare we are saying — the pinnacle of the practice, and with out it, nothing else down the road works. Therefore, all the opposite elements of the drivetrain mix to make up the powertrain, which, as a unit, “transforms kinetic energy into propulsion motion,” says authorized auto dealer Maxwell Ford.

Think of the powertrain because the all-encompassing umbrella time period that features all the transferring elements whereas the engine and the drivetrain sit fortunately beneath. But wait! What about electrical vehicles? While they’ve each a powertrain and a drivetrain, they differ from autos with inside combustion engines as a result of most EVs haven’t got multi-speed transmissions. That, nonetheless, is a subject for one more time.
