Today in Automotive History

1977 Diesel Debut

General Motors (GM) introduced the first diesel automobiles in America on this day, the Oldsmobile 88 and 98 models. A major selling point of the two models was their fuel efficiency, which GM claimed to be 40% better than gasoline-powered cars. By compressing air, rather than an air-fuel mixture, the diesel engine achieves higher compression ratios, and consequently higher theoretical cycle efficiencies. In addition, the idling and reduced power efficiency of the diesel engine is much greater than that of its spark engine cousin. However, the diesel engine's greater efficiency is balanced by its higher emission of soot, odor, and air pollutants.

I guess this just proves how strange I am as Diesel (trucks) just turn me on.

I love the sound and smell of them.

There is nothing like a F250, Power Stroke pulling up next to me that will get me all hot and bothered.
