Trucks (semi's and big 'uns) have had diesel all along. "Small cars" in America that were built by AMERICAN companies (GM or General Mismanagement) and had diesels were not that small - My BIL had a full sized luxury diesel Caddilac which he swapped the engine on, it also leaked a can of freon about every 100 miles.
From the Wicki (

It was a grand idea to get around emmission regulations and a knee-jerk response to a gas crisis but it didn't work.
During the same time period (1979-1983) I and several of my coworkers bought VW Rabbit diesels which were EXCELLENT, ran well and got 50 MILES PER GALLON routinely around town. This is when the gas version Rabbit got 30 mpg WHEN driving. However for those that were there it was also when one may idle in long lines just to get gasoline, effectively getting ZERO miles per gallon.
Only us old f@rts remember the long lines for gas and the rationing of the '70's. It was truly a pleasure for me to drive by a long line of cars waiting to fuel up while I went to the diesel pump with NO line and no worries.
GM's sudden response with a diesel engine for a passenger car was first seen as similar to America's response to the Russians in the space race. However it was a dismal failure. By 1985 almost anyone I talked to about diesel cars thought they were totally unreliable, while it was actually only another example of GM's mis-management. The average "American public" herd mentality broadened that to ALL diesel CARS, not being smart enough to realize that there were a lot of small diesel trucks. This did not apply to the rest of the WORLD.
