But, let's say you have a hybrid vehicle, which can spin the engine at whatever RPM, and toggle it on and off whenever. Is it going to be more efficient to spin the engine at, say, 3000rpm 90% load for 30 seconds out of every minute, or to spin it at 1500rpm 90% load and leave it running all the time?
This is basically the difference between 40mpg in the Prius and 60mpg in the Prius. If... Its warm enough and the cars warm up protocol doesn't sabotage me.
