My previous car was a Del Sol with a B18B and B16A transmission. At 70mph it was something like 4200rpm? I got around 30mpg cruising at those speeds, and improving aero didn't do jack. Pulse and glide helped tremendously. I expect it was nearly all drivetrian losses.

What's the combination that would result in the tallest gearing for a K series? None of the calculators I've looked at include transmissions other than those in the RSX and -S.
