That is a big win for the much larger, safer, and more luxurious 2021 Civic. The 1980 one was tiny and not something you wanted to be in in a crash.

Also, the EPA ratings have changed between now and then getting stricter and closer to actual mileage. That 1980 vehicle would get much lower mileage ratings now than it did then.
