I'm getting ahead of myself. Anyway, what kind of MPG do you see going 50-55mph?[/QUOTE]
With or without tail wind
Steady state driving:
With a light tail wind I can get 54-58.
No wind 52-56
light head wind 50-54
Adding the coasting I do from the given speed:
light tail wind 1-1.3 miles of coasting (depending on wind speed)
no wind 1-1.1
light head wind .8-1.0
my normal commute is made up of 19 miles of back roads (55MPH speed limit) and 3 miles of city (4 lane 40 MPH speed limit). On the way to work the city roads are empty and It only slightly hurts MPG. on the way home its busy and the traffic lights suck (three or 4 are blinking yellow on the way to work) but on the way home you are going to get 2 red no mater what you do and 3 or 4 is not uncommon. Half are sensor operated and no or short crosswalk signals, the rest are timed but the timing is a forced stop. After 18 months I have the cycle down and its a nasty section to do.
