Once it got going, not much could stop it. But it came nowhere near the Insight in mpg. Not counting Green Grand Prix competitions, it's best tanks were in the upper 40's mpg.
That is why I mentioned extra ballast. Great coasting is as much a function of density as it is aero drag. Fill up the hatch area with bricks and you might see 100 mph down that hill.
