Jake, we still have our 1990 Honda Civic, runs like a top, burns no oil, and gets 49 MPG around the Keys. Why did cars stop getting such good efficiency? Rick
In a nutshell, thank your US Government regulations for safety...side impact ratings...air bags...the list goes on and on and continues on. There's a lot of foreign and domestic cars sold in the US from the late 70's to the early 90's that provided excellent fuel economy. A major factor in the mandatory addition of all this regulation?
It's a sailors worst enemy WEIGHT. Look at the weights of the vehicles of then and now.
