Ok, you try getting 50+ with your engine while you're charging a *whatever* amp hour battery pack at full load...
That was kinda my point. In conventional engines, we have traded efficiency for flexibility. I couldn't get that kind of efficiency in my car. But if an engineer is told, "Hey, design me a super-efficient engine. It needs to output XhP at Yrpms. No load or speed variability, just on or off," you'd end up with a very efficient design. Probably a miller or atkinson cycle, though a brayton engine would not be out of the question (just much more design intensive). In fact, for a fixed speed and fixed load, brayton would be ideal (though not Carnot ).
