- - Canadian smart car aiming for 100 mpg (US) (https://www.fuelly.com/forums/f12/canadian-smart-car-aiming-for-100-mpg-us-2234.html)

I spotted a smart fortwo here the other day. It was booking along in the left lane in a 70 mph section.

Even if they officially bring it here, I doubt the diesel would be an option. What American buyers want and all that.

I've done a couple runs now on B80, but the mileage results aren't spectacular. About 90 mpg imperial... not that close to the 113 I got last year.

I am reducing the biodiesel content on Wednesday and running again. We'll see how it goes I guess. Wind has a big effect on the smart.

BTW - I am running 43 PSI cold. Cruise control, 81 kmh ( 51 mph ), and not much else...

Hi Smartsuuk,

A few questions:
1) Is the underside fared?
2) Any plans to do some aftermarket aero mods to it?

Thanks in advance.

the underside of the car has covers, which may help

I also have a front spoiler

Here's the story from my site:

Mission Complete
Posted by NRG SVR in 100 MPG Challenge | Edit
7:45 pm, Wadena, SK
Excellent wind conditions today, blowing from the south-east, allowed me to accomplish my goal of beating 100 miles per US gallon.
I departed Yorkton, SK at approx 4 pm and made a near perfect 81 kmh trip to Wadena, passing through Canora on hwy 9, and then through Buchanan, Rama, and a few other small towns on Hwy 5.
As per the GPS, the trip was 151.13 km. I filled at the Wadena Coop - twice in fact - to make sure the fuel level was as full as it could be? I filled 3.104 litres and then another 0.273 litres - and each time painstakingly made sure there was no foam. Even 5 ml overflowed. I was brutally AR on this, more than ever before - the Coop attendants were curiously dumbfounded as to why, but nevermind. :-)
151.13 km on 3.377 litres works out to 44.75 kms to a litre, or 2.23 L/100km.
That in turn works out to 126 mpg (imperial), and for my US friends, 105 mpg (US).
I had dwindled the B80 biodiesel I ran with yesterday to approx B20. I will recap this in detail later. Temperature today was 24 to 26 celcius.
Also - I did make this trip with all of my luggage and extra biodiesel. Based on a government scale yesterday in Melfort, let?s call that 80 kgs, or 170 lbs, minimum, probably more, as I picked up another 15 litres of biodiesel today at Foam Lake. The car and luggage scaled in at 810 kgs yesterday, and I?m 110 kgs.
I have some pictures to post of course, but for now, I?m going to shower and get a hot meal. A storm has also moved in, and lightening with it.

This was my fourth serious attempt at beating 100 mpg US since yesterday. I only wish the distance had been longer, but I am out of weather (and time) to do anything further in this area this time around.

so this thing costs $15,000 US dollars????
Is this what I am reading??

$15k is kinda steep. Doesn't matter if it's getting 100mpg. Sorry but 15k is too much.

An extra thousand over the yaris sounds good to me.
