The 4 cyl,s of today are geared to run higher rpm at cruise speed simply because of stiffer emissions standards. They aren't clean enough when they are "lugging" at 1500 rpm at 55 mph like the older ones and like the 3.8 v-6. Any engine that is turning 2200 rpm at 55 is not gonna get 30 mpg!

Guess the joke was on them,eh?
