On a steep grade, the Insight will burn less fuel during the climb even though the RPMs were higher due to the EV assisting. The instant MPG rate will show poor milage, but the overall MPG will climb. While the milage appears poor for a short period of time, there is a "happy spot" where the shorter burn duration uses less because of the EV assist. Wanted to see if the CMax would respond the same way.
I might add that the Insight hypermilers recommend full acceleration from a start in order to get the EV to kick in. Again, as traffic and speed limits allow.
