During the gasoline price surge in the early 1980s, the cost of diesel fuel was significantly less than gasoline, resulting in new interest in diesel light-duty vehicles. Many manufacturers at that time produced diesel cars and light trucks. In model year (MY) 1984, there were 101 different models of light vehicles with diesel engines, including many common models like the Chevrolet Chevette, Ford Escort, Buick Regal, and Toyota Camry. Diesel engines in light vehicles, however, were not widely embraced by American consumers and by MY 2000, there was only one manufacturer selling diesel light vehicles. A slow resurgence of diesel models culminated in 2014 with 24 diesel models. By MY 2017, four different manufacturers had 11 light vehicle models for sale with diesel engines.
