A vehicle powered by gasoline; an automobile that runs on gasoline fuel.
From 'gasoline' plus the agent noun suffix '-er,' created in the early automotive age to distinguish gasoline-powered vehicles from electric cars and other alternatives.
When cars first appeared, 'gasoliner' was actually competitive terminology—it was one option among many, and early 1900s consumers could choose between gasoline, electric, and steam-powered vehicles, making the term pragmatic rather than generic.
