This 'Achates' engine is now going into the F150. It's claimed to be 45% efficient compared to an average of 25% for most engines.
a) So if that tech were applied to the Elio, and going to a smaller displacement for the same power output, in theory you could have a 151 mpg Elio compared to a 25% efficient engine.
However the Elio engine is a bit more efficiently implemented.
b) Let suggest the Elio is an optimistic 30% efficient in this application, then the Achates of same power output could make a 126 mpg result.
c) But the torque and other issues of the Achates design may not be as compatible in an Elio application, plus lets just keep the same displacement and estimate the resulting efficiency equivalency at 40%. That would be a vehicle at 121mpg.
Anyway, seems with Achates tech the worst case seems to be a 110-115mpg Elio. And the best case seems to be 145-155mpg.
But in my car concept? low 150 mpg, high 275mpg.
And then, let's consider Hybrid design....
