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.

Thanks for the
straightforward explanation. I do have some questions though for my HCH2:
1. I dont like the idea of shutting down the ignition with key during the glide - are there still significant FE benefits if I switch from D to N during the glide (keeping ICE "running")? In N, Seems like the rpms drop to <1k and FE does rise versus keeping it in D at least.
2. Is keeping the rpms below 2k or 2.5k still a good rule of thumb for the pulse - or should I try to max out EV assist at higher RPMs?
3. Are there better FE benefits using this in slower city driving (stop lights/signs) versus using this on faster freeway speeds?
4. Is this
better FE (for an HCH) than just keeping it in cruise control at say 35mph versus P&G from 45-->25mph?
