Now I could certainly be wrong, but I think that given that even the best diesel is only 40% efficient (60% of fuel goes to waste heat) that any vehicle, regardless of gearing or aerodynamics or turbo or whatever, would potentially benefit from P&G, so long as the glides were at least twice as long as the pulses, because then for 2/3 of the trip, that 60% loss is eliminated.
In other words, because ICEs are SO inefficient, just having the engine turn actually takes more fuel than actually moving the car. Therefor the greatest potential reduction in fuel comes from it not turning at all.
Someone please explain to me differently if I am missing something.
