Best tank on my dsl smart car

[GasSavers_Antoine]

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.

That is a fantastic result, over a whole tank!

We are so lucky to have over 10,000 of these things on the road throughout Canada. The best I've done in US MPG is 74 MPG, but then I don't try too hard

Very impressive and dedicated driving. I don't think I could go 35-40mph for that long.

Wow. Felicitations, Antoine!

Someone finally hit the 100+ MPG tank, and it came out of left field! Good job! Thanks for sharing it wish us.

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.

I read this week that the new TDI smart will be even more efficient than the first version, as well as being slightly more powerful in a slightly heavier car.

Outstanding. Very nice job. 34 mph average speed for a tank is what I do just about every tank. So that's a practicle and solid 100+. Great job.

The % improvement in the new model they cite for the model 451 cdi is against the 2006 model European model 450 cdi, which was a botch-up job with short gearing and open loop particle filter.

The first cdi was rated at 3.4 L/100 kn in the NEDC cycle, and the new one is rated at 3.3: an improvement, but not as large as it may seem.

Still, I wish it was sold here....
