Sure, 25-43(34)P&G means:
- 25 miles per hour minimum glide speed
- 43 miles per hour maximum pulse speed
- 34 miles per hour average speed on level ground
- P&G is pulse and glide
This defines P&G in a form that anyone can replicate. It also means that with a steady-state, MPG vs miles per hour chart, we can evaluate the effectiveness of P&G versus just setting the cruise control to the same speed:
I have found only one practical use of P&G with my NHW11 Prius, during the warm-up phase. Using a block heater or thermistor hack eliminates this very limited, 3-5 minutes. In all other cases, it is as or even more efficient to use steady-state speeds for 35-38 miles per hour. I simply choose routes that have 4-lanes and maximum speed limits of 40-45 miles per hour. Huntsville is fortunate to only have a 'rush minute'. But rush hour congestion works just fine for a Prius if all of the other elements have been addressed.
