powertrains
Vehicle propulsion systems
Powertrains are the components that generate and deliver power to move a vehicle—typically the engine, transmission, driveshaft, and axles working together.
The term appears most often in automotive contexts: Electric vehicles have simpler powertrains than combustion engines.
A powertrain warranty covers these mechanical systems specifically.
