I'm no Prius expert, but I do know that when I coast, there are green
arrows from the wheels to the motor/generator, and from the
motor/generator to the battery.  Look at the energy screen when coasting

Support the troops:  Bring them home ASAP.

Efficiency has nothing to do with it. What others were saying was that
the best *economy* can be had by not spending energy than one is
promptly going to shed with the brakes.

If one must shed energy with the brakes the Prius has a means of
recovering *some* of that energy. Is not terribly efficient but its
better *economically* than throwing it away as heat.

Elmo understood all of it.

   Actually, accelerating slowly is NOT the way to get the best fuel mileage
in a Prius.  You are better to accelerate rather quickly (not full throttle,
but close to it) and then back off and "glide," letting the ICE shut-down.
The Prius Atkinson-cycle engine has the best "specific fuel consumption",
i.e. produces the most horsepower per gram of fuel used, when the power
output is rather high, and the rpm is in the 2,000 - 2,300 range.  This
"Pulse and Glide" technique produces the best MPG figures.
