I think P&G is the most commonly misunderstood term on hybrid forums and is often cited in situations where the reference is incorrect. Don't misunderstand me, P&G is a proven and valid technique for improved FE. It's just that I think it has limited applicability in typical commuter traffic conditions. If you try to use it in heavy traffic, then IMHO you chance the frustration and ill-will of drivers behind you, and that sets a bad tone relaive to the hybrid community for these drivers. If the objective here is to expand the hybrid community -- for whatever reasons each of us harbors, then this action is contrary to that goal.

With my new TCH, I am rapidly discovering that the "heretical mode" is a far more practical technique to achieve vastly improved FE anyway. I do not know if a parallel situation exists in non-toyota hybrids, but this electronic recirculation mode has proven to me to be most useful in heavy commuter traffic moving in the 40 to 55 mile speed range (which is most of the time in my own commute). This operating state maintains those speeds over reasonably level terrain for extended periods with the MPG indicator either pegged at 60 or on mild uphill grades moving up (down) to 45 or so. That is great mileage for a mid-range speed in my middle weight hybrid. It is also reasonably compatible with traffic flow, so no-one gets held up behind me.

It is the ignorant among us that will eventually destroy us all.
