I do not feel that cars have become significantly more efficient over the years, what do we say? They become bigger and heavier, while more or less maintaining their fuel economy?
They do seem to have become more powerful.
Eric the Car Guy bought a 1979 Ford Fairmont with a 3.3L six-cylinder with 85 BHP. My 1987 Honda Prelude Si had a 2L engine with 110 HP, my HX has 115 HP out of 1.6L, and the current Civic gets 143 HP from 1.8L.
While Civic engines keep growing, aren't manufacturers making smaller engines that are as powerful as their older ones?
Isn't that some kind of progress?
