Now that May is finally acting like May, I can make recurring trips with the soft windows removed and the top lowered. Previously, I'd sneak in an occasional drive with the top in the Sunrider position as conditions would allow.
I've accumulated enough miles to notice a consistent 1.x mpg reduction in fuel efficiency with the top down, when compared to the same trips (errands) on the same roads at similar times of the day. Have any of you observed an efficiency penalty when comparing sustained top up to top down driving?
