Tested rpm-mpg

[basjoos]

The 92-95 Honda Civic VX and CX turn 1925rpm @ 60mph (2000rpm @ 100kmh). My CX when it had its original engine with 70 horsepower had enough power to maintain speed on all except for 3 of the uphills on the interstates in western NC. And on those few hills that it won't maintain speed on in 5th, well, that's what 4th gear is for.

...a very crude "rule-of-thumb" estimation of MPG for our Cruze LTZ seems to be:

MPG ~ 2000 / MPH

Exactly! Honda has been downright stupid with gear ratios since 1995. Exceptions were the HX which was ok but not great and the Gen1 hybrid but that had other stuff tacked on. Even now, the new Hf model they're advertising... automatic only.

Ugh, stop, you are bumming me out. My Element, with plenty of engine and plenty of torque, is geared so low. At 60 mph, I am running 3000 rpm. If it were properly geared, it looks like I could break 30mpg on highway tanks, vs the ~26 I get now. Sigh.
