drivetrain
drivetrain
Noun
pl: drivetrains
This term describes the entire mechanical sequence that transfers energy from a power source to the point of contact with the ground. It is a collective noun encompassing several distinct subsystems, meaning it refers to the holistic assembly rather than a single part.
In automotive contexts, it is used primarily in technical manuals and by mechanics to distinguish the power delivery system from the engine itself. While the engine creates the power, the drivetrain manages and distributes it.
