Car: Prius C.
this is cross-post from PC, so bare with being fragmented
Original:
was traveling last weekend. After stopping for gas and pulling back to interstate, "from the start" MPG was holding on at steady 38-39MPG. This is on flat surface with cruise set at 73mph, ECO on and instant consumption staying in green zone.
and it was like that for 1.5-2hr, until we pulled to lower speed limit zone and dropped speed. Gen3 in such situation would get 6-8MPG more.
It normally gets 58-60MPG in commute.
