And a good driver. Further more a good manual with a good driver, heck even with a bad driver a real manual transmission will get far better mpg than a automatic.
6.5-8 manual, 5-6 with a automatic.

A over-stroke engine at lower RPM is going to be more efficient than a smaller engine size that would require a higher RPM for the same power.
What I've heard from some one I know that ran a trucking company, if that an RPM governor makes the driver actually use his gear box, rather than revving up to redline, and skipping gears. HUGE fuel savings in this case.
A speed governor helps in that the drag at higher speeds increases quite stiffly. From a safety stand point, I'm not sure I'd go this route.
