What are the most fuel efficient old cars? ?

Curious saw ads from the 1980s of fuel efficient cars, I was curious what were some of the most fuel efficient cars back in the day? (What are still drivable cars that have good mpg from 1970 onward?)

    fuel changes too, daddio.....in the 80's I bought a 67 ford, that still had the original motor, rated at higher octane that was available at the time, it was pre-alcohol based, but slowly it was changing, anyways a book talked of mixing octanes to raise it higher so the knock it got stopped knocking when I mixed fuels, til when no alcohol was no longer available.....so don't forget the octanes, your good deal may bite you in the azz

    if it knocks.....

    The Honda CRX achieved 40 mpg to 50 mpg with the 1.3 liter engine.  They are hard to find.

      Yeah, because the paper thin sheetmetal tin can cars rusted away to nothing. They were so light and flimsy which is why they got good mpgs.

    Back then, the most fuel efficient cars were Japanese cars like Toyota, Honda, and Mazda. Of American cars, the Ford Escort was easily the most popular fuel efficient car. The most popular German "econo-box" was the VW Rabbit. 

    Until the 1980s, fuel efficiency wasn't ever a focus. It took until the oil crisis for that to become a thing, and then after that, it took several years, until the beginning of the 1980's, for car makers to really start bringing fuel efficient models to market, models where fuel efficiency was an objective. In fact, that's how Japanese car manufacturers broke into American markets, because they were the first auto manufacturers to bring cars to market where fuel efficiency was a major factor in design and a principle selling point.

    Honda Civic 1970’s got 40/highway but today it’s probably 30/highway if it’s still got original engine.  VW Rabbit pickup truck got 30/highway so figure 22/hw today
