context_page_description: In a motor vehicle, the powertrain comprises the main components that generate power and deliver that power to the road surface, water, or air. This includes the engine, transmission, drive shafts, differentials, and the final drive. Hybrid powertrains also include one or more electric traction motors that operate to drive the vehicle wheels. All-electric vehicles eliminate the engine altogether, relying solely on electric motors for propulsion. Occasionally the term powerplant is casually used to refer to the engine or, less often, the entire powertrain.
  A motor vehicle's driveline or drivetrain consists of the parts of the powertrain excluding the engine. It is the portion of a vehicle, after the prime mover, that changes depending on whether a vehicle is front-wheel, rear-wheel, or four-wheel drive, or less-common six-wheel or eight-wheel drive.
  In a wider sense, the powertrain includes all of the components used to transform stored energy into kinetic energy for propulsion purposes. This includes the utilization of multiple power-sources and non–wheel-based vehicles.

Hybrid powertrains also include one or more electric traction motors that operate to drive the vehicle wheels.  All-electric vehicles ("electric cars") eliminate the engine altogether, relying solely on electric motors for propulsion.
