models have an only engine (or electric/hybrid powertrain) option available, while other models have multiple powertrains available such as Front Wheel Drive, Rear Wheel Drive and Four Wheel Drive.

In North America, a model can also be called a nameplate. The Chevrolet Suburban is the oldest automobile nameplate in continuous production, dating to 1934, and the 1940-1996 Chrysler New Yorker was another long-running North American car nameplate.
