Technicaly pulse and glide has nothing to do with engine on or off. It is just more efficient with the engine off.

Pulse and glide was taught in drivers ed as a way to conserve fuel if you were running out. It is simply accelerating to a speed and then coasting a good distance and then back up to speed and coasting again. It has nothing to do with engine on or off. Since the Prius' HSD will allow you to go into a no energy mode it is one of the best vehicles to perform this technique and prius owners have come to adopt the technique as their own, but in reality pulse and glide is more broad then the use of it in a prius.
