Toyota and Honda seem to have done an exceptional job at maximizing fuel efficiency in their minivans. About a week and half ago I drove 3 hours on the highway in my family's minivan averaging no less than 5 mph below the speed limit and no more than the speed limit, and coasting just a little, and averaged 32.5 MPG for the whole trip with probably a thousand pounds worth of weight from passengers and luggage. It did get up to 33.1 MPG before we exited the interstate and all the weight killed MPG in stop-n-go traffic where we "only" averaged mid to upper 20s MPG.
Our van ('04 Toyota Sienna) is only rated at 25 MPG highway compared to the 28 MPG that the Odyssey is (I think the new Pacifica is rated the same as the Odyssey)? Beats me how Fuelly says the average minivan driver gets only 18-20 MPG....
does this mean a 40 MPG minivan is possible with hypermiling and ecomodding?
