the mileage and estimate the MPG (the max the HCHII can read on
trip is 150mpg).
4. When you reach your desired low speed turn key to on position till
the ICE starts, depress accelerator slightly to increase revs and shift
into drive.
As far as coasting resistance I can only compare to a Nissan Altima that
I tried coasting in Neutral a few times and it would drop speed very slowly
in comparison. That's why we need an experianced FAS driver to try it
out in the HCHII for a comparison.
Also one of my issues with FAS once you end a segment you then have to
accelerate back to a desired driving speed again which drops your mpg during
the process. I basically like to get to a desired speed then backoff on the gas
pedal as much as possible without dropping speed, then I can cruise at
70 mpg and higher for as long as traffic does not interfere. I do use P&G
alot but only with hills and stop & go traffic, I don't go looking for a P&G
opportunity they just show up as part of my traffic conditions.

What you are talking about is P&G (which I generally do not use). True you do FAS whild P&Ging but what I call a FAS is when you do the same thing as a regular AutoStop (while stopping) just a lot sooner than the car would. I guess I also call it a FAS when you kill the ICE near the top of a hill and let the downhill maintain your speed. P&G is the same thing except on the flat when you are not thinking of stopping. I might not be useing the terms correctly but I don't FAS on flat land unless I need to slow down or stop anyway. I FAS all the time on downhills or when coming to a stop.
If someone knows more precise terms please post em.
