Engine size + RPM + MPH = Best MPG?
I've always been interested in the efficiency/power of my engines. The MINI's OBC has a "constant econ" digital readout and I believe that traveling 68MPH in 5th @ 3000rpm is more fuel-efficient than 55MPH in 5th (or 4th). Partly due to having more torque/HP at higher speed permits the car to climb slight hills with less additional throttle required.
However, one day I drove along Skyline Drive's twisty roads in 3rd, revvying heavy, and econ still read 35mpg !? and avg the same at next fillup.
My suggestion for reducing consumption: MANTAIN SPEED!
I don't care if you're driving 55 or 70, just stay that speed.
