What is the Powertrain exactly?

I've heard a lot about the Powertrain and was wondering what it is exactly, what it is not and how it enhances the vehicle and what its main purpose is.

Thanks!

The powertrain is the engine, transmission, and rear axle. If its 4wd add the transfer case and front axle.

The powertrain really is a hold over in English from earlier times when we had horse drawn carriages, steam power, etc.

Essentially its a term that applies differently to different applications ... But we use it now exclusively for internal combustion engines.

Anyhow the original use of the term comes from the 15th century.

wheelwork consisting of a connected set of rotating gears by which force is transmitted, or motion or torque is changed

Here's the Wikipedia definition.

Powertrain | powerplant | running gear
refers to the group of components that generate power and deliver it to the road surface, water, or air. This includes the engine, transmission, drive shafts, differentials, and the final drive.

I get it now. So, the powertrain is multiple/group of components?
