I just wanted to see how far down in fuel consumption I could go with this car without modification, just by judicious use of HE rules of driving. ( HE = Hyper-Econo).
The result : 1063 km on 23.8 liters for 2.24 li/100 km.
660 miles with 6.29 gal of fuel, for 105 MPG
So my rules were : a full tank 1000+ km ( 630 miles), non-modified basic car, return trip, and without any tricky help like a tail wind. It could be done in one day or several days on the same tank, but always returning home on the same day to have identical climatic conditions on the return leg.
I did it on 4 days. I went on 4 lanes highways and rural roads. Wind was mostly light and twice up to 10 knots. Temperature was on the cold side, once down to 5°C, and up to 23°C. Topography mostly flat with light ups and down. The only modification to the car was the tires inflated to 44 psi.
I have lots of intermediate datas but of no interest to most. Scangage2 gave an avg speed around 34 mph most of the time and max speed around 44-50 except once 57 mph.
kickflipjr, it is indeed difficult to go 35 mph for almost 20 hours. Even doing it in 4 days is mind bogging. One has to check speed in relation with gas pedal, the topography of the road to increase or decrease power at the right time, and check at all time incoming traffic, mostly coming fast back so not to be rear-ended, and also at the same time respect other drivers, mainly semis. I had to go on the side of the highway a few time, to let semis pass. After four hours a day, my mind was very tired and I could hardly concentrate at the end.
Very happy to resume my regular driving around 70 mpg. I have been HE driving for the last 3 months, thus showing an avg of 89 mpg, while my car life avg is just below 70.
Too bad Hockey4mnhs, you can't get one of those DSL smart in the states. They are wonderful gas savers with their small 800cc, 41 hp, hi-tech powerplant. Not perfect for extreme hypermiling, since their 6 speed sequential doesn't allow a perfect choice of speed, nor pulse and glide, but wonderful economy car for everyday use. The new us introduce 1000cc mitshubishi gas engine smart should be an interesting choice, even if more thirsty.
