As far as his grandfather's 60 yr old idea, the concept of variable valve timing to take advantage of both horsepower and mileage has been conceptual for a very long time, although in Grandpa's day the mechanism would have been a mechanical one most likely.
Taking it a couple of steps further, a solenoid valvetrain would make cylinder deactivation a simple affair. Over on a couple of mopar/hemi forums the general concensus is the the hemi would cruise just fine on 2 cylinders, the penalty being engine vibration. The engine could also switch between otto cycle and atkinson cycle depending on demand.
