I have a hypermiling question on hills if anyone has any experience.
My speed limit is 60mph, and I have been ranging 45-65 mph when no one is around. Using "L". While on the incline, I slowly let the car decelerate (slowly release gas in "L") as low to 45. At start of the decline, I start accelerating (slowly) the car until it reaches 65, then let it regen back to 55 on the flats.
Does this conserve or benefit the overall mileages? Does gravity on the incline help with accleration where it woudl be effective to accelerate faster on the decline and conserve more by decelerating slower in the incline? Does regening energy when the wheels are spinning at 65-55 produce more energy effectively than to have a constant speed?
Or, would I have been equally off by setting the cruise control to 60 mph?
