Canadian smart car aiming for 100 mpg (US)

[MetroMPG]

I got an e-mail from the person behind the web site 100mpg.ca (http://100mpg.ca)

He started the site a year or so back as a personal project to raise awareness of a Canadian federal greenhouse gas reduction program. His goal was to drive across the country, raising awareness, while aiming for a target of 100 mpg (Imperial).

He's also seen some FE numbers close to the 100 mpg (US) mark, and he's aiming for that next (for a single trip).

I invited him to drop by Gassavers to let us know what he's up to. He had some good questions about tire sizes, pressure, rolling resistance & weight reduction.

I'm particularly interested to hear about the specific driving techniques owners of these cars use to get the highest efficiency. They're 3-cyl 799 cc common rail diesels with sequential gearboxes. A whole other kettle of fish compared to most of our cars!

The smart along side one of University of BC's "IT" electric cars. (Funky NEV's made in the Vancouver area: http://www.itiselectric.com/ )

I can't make heads or tails out of that 100 mpg site...where's the data??? :D Yeah, I know - he's making more of a statement than crunching numbers.

I actually like the utility version if the IT car...kinda neat. I wonder what the prices are...

[MetroMPG]

In the right column of his site he has his FE image showing 3.6L/100 km. Click it and you get to this page with his full history:

http://www.spritmonitor.de/en/detail/119856.html

(Unfortunately the Metrically - and German - challenged may have some fun translating the data.)

Price of the IT is around $15k US. A competitor (another Canadian company) makes a 2-seat NEV/LSV that starts around $10K US:

[MetroMPG]

Oh, and I forgot to mention: he told me in his e-mail that his first car was a Suzukiclone.

Obviously this guy has smarts. :D

$10k...that's about the cost to build a decent one...if you're not going with the ForkenSwift method...:D

[MetroMPG]

True. But you know what? It's a LOT of work. :eek:

[kickflipjr]

I have seen the 100mpg site before.

Smart cars are cool, but they are not being sold in the US yet. or If they are it is in very limited sales.

Speaking of limited sales...

I saw a lotus eliese on the road the other day.

[MetroMPG]

They're selling them through ZAP! - at around $25K US (they start here at around $17K CDN). I read somewhere that ZAP recently delivered their 200th one.

[95metro]

True. But you know what? It's a LOT of work. :eek:

Yeah, but you know that's the price you pay for a hobby, isn't it? If our brains didn't find it fun we wouldn't do it.

Hard work = enjoyment & satisfaction & fun (with some occasional pain and frustration mixed in)...:cool: :D

[Randy]

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.

[smartzuuk]

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...

[Mighty Mira]

Hi Smartsuuk,

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

Thanks in advance.

[smartzuuk]

the underside of the car has covers, which may help

I also have a front spoiler

[smartzuuk]

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.

(source) (http://100mpg.ca/?p=130)
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.

[Compaq888]

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

[thisisntjared]

so this thing costs $15,000 US dollars????
Is this what I am reading??cheapest benz 3V4R!!!!!!

[Compaq888]

cheapest benz 3V4R!!!!!!

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

[SVOboy]

An extra thousand over the yaris sounds good to me.

[Compaq888]

An extra thousand over the yaris sounds good to me.

try $2k

[SVOboy]

I wouldn't pay anything more than 20% under sticker, but that's just me...

Besides, a new car, 15k, safety, reliability, low cost of ownership, waste oil power...

[thisisntjared]

woah woah wait wait wait.

are you saying you wouldnt pay $1-2k more for a mercedes over a toyota?????

i definitely would.

[SVOboy]

I'm not particularly in love with mercedes anymore, now that it's sold out to the devil.

[Compaq888]

woah woah wait wait wait.

are you saying you wouldnt pay $1-2k more for a mercedes over a toyota?????

i definitely would.

I WOULDN'T BUY mercedes if it was CHEAPER than the toyota.

[90CivicStandard]

There's a dealership that I drive by every day that has a few of these.

Funny thing is it's an exotic car dealership. lol

I thought they would be more than $15k. That actually sounds pretty reasonable to me. I wonder if the ones at the local dealership are diesel??

I should stop by and ask, although I wouldn't get much help rolling into an exotic car dealership in my 90 civic. lol.

[thisisntjared]

man your loss, guys. the smart feels wonderful to drive. for city driving there is nothing better. other that a bicycle or a comfy set of free trade shoes.

[The Toecutter]

I'm interested in the Smart Roadster-Coupe. But I'd be much more interested if they used a 200+ horsepower straight 6 turbodiesel. Since no one is making a car like that(too fast for its own good AND fuel efficient), I'll spend some time drooling over the VW Eco Racer concept.

[smartzuuk]

It's October now, and I've really kinda maxed out on what I can accomplish with the smart. Yes, I could acquire the 3.5 fron wheels from Europe with 135 tires (these were originally used with the CDI in Germany), and mount the fronts on the rear (145) and go for some new high... but really, I need a new set of wheels.

I have been contemplating acquiring an Insight, just to see what I could do with one of those (a 5 speed to be sure)... I'm thinking that day in and day out the Insight would get me 20% better mileage overall - but would it really beat the smart on a single run on the highway?

[kickflipjr]

I am glad to see you put your car in the gaslog.

I don't know heard of it but the jet car is the same engine as the smart but achives much higher mpg due to weight reduction and better areodynamics.

[MetroMPG]

Hi smartzuuk...

Thanks for the update. I keep seeing the little smart beasties around town (was coasting down a long hill behind one just yesterday, as a matter of fact). I'd jump at the chance to drive one with a fuel economy display hooked up.

As for the Insight, there are a couple of owners on this forum who may pipe up with an answer.

Dan (krousdb) owns an older Civic VX hatchback with lean burn, and he can maintain 75 mpg (US) in steady 55 mph cruising in warm weather. I suspect the Insight can exceed that, though my understanding is that its lean burn "window" is narrower than the old VX.

[omgwtfbyobbq]

I've heard ~85-90mpg@55mph average speed for the Insight from the horse's mouth, but I'm not sure if that's with lean burn or not. I know that it can go all electric at learn burn for a solid whatever mpg at a slower cruise with MIMA, but I don't think it can do 55mph all electric.

[rh77]

The secret to driving the Insight is to neither use the charge, nor the assist to get the best FE -- basically all engine. At 55, I'm guessing that a little electrical assist is necessary to overcome the wind resistance. Keep in mind that you have to use the ICE to recharge the batteries if you use them exclusively (unless you do a plug-in setup :thumbup: ) Otherwise, if the battery gets too low, you get a "Re-Calibration" of the battery back that evens the charge in each battery, and commands re-charge (which kills FE). Rather tricky from what I understand.

RH77

[omgwtfbyobbq]

Eek, sounds like it. I suppose that's where the big advantage of the Prius' parallel/hybrid setup comes from. Going pretty OT, I would absolutely love a plug-in diesel or gas hybrid that's based on something like the 1L with either a small gas or diesel engine that provides enough oomph to cruise at ~55-65mph. We'd get the price per kwh/efficiency advantage of the BEV most of the time, with the optimized gas/diesel engine efficiency for longer trips. Performance would probably be better than a straight gas or diesel setup like the UFE-III or 1L.

[Rstb88]

MetroMPG where did you get the pricing for the IT car cause. I want one.

[MetroMPG]

http://www.zapworld.com/cars/salecars.asp

There's a used 03 IT partway down that page for $9K. Shows $15K as its new price.

If you go to Dynasty's web site and go through their dealers' sites, you'll probably find more info. http://itiselectric.com

[Rstb88]

none of the dealers near me listed prices...

[smartzuuk]

I drove an Insight today. First impressions - I need to see someone drive it that knows WTF they are doing. I drove conservatively, and got a 5.2 L/100km... not so hot.

Also - I was thinking of putting the smart on eBay with a link gassavers - I usually get 1500 views on a smart diesel ad... I do it simply for promotion purposes (for my site www.100mpg.ca ). What does a scanguage look like and what does it do? I need sometthing to make my driving more interesing. Honest. I'm thinking I should get a turbo boost indicator of some kind in the smart. And a set of those 3.5" wheels with 135 on the front... and put the 145 (on 4") on the rear... 55 PSI... and you know, go for a LONG I5 trip...

[Compaq888]

I have seen the 100mpg site before.

Smart cars are cool, but they are not being sold in the US yet. or If they are it is in very limited sales.

Speaking of limited sales...

I saw a lotus eliese on the road the other day.

I see the lotus elise all the time here.
I live where all the drug dealers, rappers, movie stars and rich people live. So far I've seen at least 4 in the last couple of months. The only car I'll really drool over is the Ferrari Enzo and the BMW M5. Seen 2 M5's in the last couple of months and saw one Enzo.

In city driving you have to maximize use of the Auto Stop (engine off) feature. The super-high FE drivers install a switch to manually force Auto Stop when coasting or waiting at lights, etc. That's the FAS acronym you see all over this site (also applied to non-hybrids when drivers stop the engine manually via the key or installed switch).

Using FAS with the pulse & glide or CODfishing techniques will return the ridiculously high FE numbers achieved at lower average speeds (e.g. sub/ex/urban speeds).

Also, ironically, you should be attempting to minimize use of the hybrid system, which minimizes battery depletion, which reduces the charging load placed on the engine when the SOC drops.

In highway driving, you aim to get in lean burn cruise and stay there.

I hope some of the Insight experts will chime in and add to this, or correct my misinformation (I've only ever ridden in one, not driven one). It may be worth starting a dedicated thread if you want to pursue it. They may not be reading here.

[rh77]

What does a scanguage look like and what does it do?

It's the best thing since sliced bread:

ScanGauge (http://www.scangauge.com/)

The manufacturer just released an updated version with added features.

Basically it gives you instant feedback on a variety of items: (MPG (or L/100km), intake air temp, throttle position, speed (which often differs from the speedometer), manifold absolute pressure, etc. It helps drivers know what the car "likes" to get good FE. It also pulls "check-engine" codes and has a trip computer.

RH77

[smartzuuk]

They claim it works on ALL, except those specifically noted as incompatible. I really wonder if it would work on the smart.

We have some comptuers from misterdotcom.de that do work, but even then we aren't sure about the calibration... is the mileage really that accurate?

I take it the Insight drivers getting ridiculous numbers would be better off pulling out the hybrid system (so to speak), and make the car lighter. It sounds like Auto Stopping is the trick in urban, and the aerodynamics are the trick on the highway. Neither need a hybrid system to work. Someone really should try putting a smart diesel in an Insight, oh wait, wasn't I already thinking about that? LOL

[smartzuuk]

Oh, so I finally found the definition for CODFISHING (http://www.gassavers.org/showthread.php?t=1783&highlight=codfish), and I cannot employ that method in the smart... not a good idea.

I was thinking about covering the rear wheels (like some here have done), and pehaps adding a vortex generator or two or three to the back of the car. I think the smart is .38 CD, which is bad...

I guess the challenge would be to find 3-4 things I could do to get the aerodynamics improved and/or decrease the rolling resistance.

[MetroMPG]

but even then we aren't sure about the calibration... is the mileage really that accurate?

My SG1 is very accurate and was calibrated very closely out of the box - within 2 percent. I have tweaked it further, and it was within 0.6% on my last fill up.

It sounds like Auto Stopping is the trick in urban, and the aerodynamics are the trick on the highway. Neither need a hybrid system to work.

You pretty much hit the nail on the head. Also, lean burn on the highway is the trick in the Hondas.

Oh, so I finally found the definition for CODFISHING, and I cannot employ that method in the smart... not a good idea.

I take it that's because the smart has the sequential gearbox, yes? You can't simply go from, 4th gear to neutral, for ICE-off coasting, then from neutral back to 4th.

I guess the challenge would be to find 3-4 things I could do to get the aerodynamics improved and/or decrease the rolling resistance.

Rear skirts may gain you a couple per cent at highway speeds. Not sure about the VG's - read about them, but haven't tested them. As for rolling resistance, not much you can do there except possibly opt for LRR tires, increase tire pressure, or lighten the vehicle.

[The Toecutter]

Toes: I'm curious, what do you drive and where do you drive it?

My current daily driver is a 1994 Suzuki Sidekick. It's my step mom's. It's very slow, tops out at ~75 mph on flat ground, 0-60 time was over 20 seconds. It needs a tune up, which is probably why the performance is so poor. If I drive it like normal, full throttle to accelerate(which comes just short of keeping up with traffic), and 65-70 mph on the highway, it gets around 16 mpg. I can eek near 30 mpg out of it at a steady 50 mph, which is what I've been doing, and getting tailgaited very frequently as a result. An 18-wheeler even tried to run me off the road. It's not fun to drive and if I don't get enough speed going up a freeway on-ramp, I'll have to pull over on the shoulder and wait for the highway traffic to clear, because it isn't safe to merge into 70+ mph traffic at 15-20 mph. This POS easily gets stuck on steep hills, and thus I have to find alternate routes to them.

When I was a teenager, I had a 1996 Ford Contour with a Diablo performance chip and MSD ignition system. 0-60 was ~7 seconds, and with the electronic speed limiter rendered useless, it buried the 130 mph speedo. Stock these made 170 bhp, but I don't know what the modifications upped the power to. Given the 15.0-15.5 second 1/4 mile times achieved at Gateway International, my best guess would be ~190 bhp. Gas mileage was so-so, between 25-30 mpg. My favorite places to take it were Route 15 between Belleville and East St. Louis, and the rural areas near Freeburg, Illinois. What is currently keeping it off the road? Needs the entire emissions system replaced, needs a new alternator, and the engine itself is about ready to give out. It sits in the driveway.

I have the GT6 as well. That is my project car. I haven't taken it out much, as it doesn't have up to date license plates on it; if I get pulled over, I'd be ****ed. But it has been excellent to take out into the country to go hooning in the middle of the night while stoned off my *** with a friend. The engine has been bored to 2.5L displacement, and flooring it sounds like a Harley Davidson getting ***-raped by a Formula Race Car. It's loud enough to set off alarms of parked cars. It will be an electric car within months after getting my electrical engineering degree, as engineers make quite a bit of coin and it won't take too much cash to convert(Parts ~$10-12k in total). The straight 6 will be sold on Ebay, and in its place will be a WarP 9" series DC motor, Zilla 1k HV controller, and perhaps a 300V+ pack of Exide Orbital AGMs. This combination would give 0-60 mph ~5.5 seconds and a top speed in excess of 140 mph limited by RPM, at least according to simulation. With extensive aeromods, range could be 100 miles at 65 mph. I could do a cheaper 156V setup that would have similar acceleration and range using larger sized batteries, but it would only top around 120 or so; this would shave $4-5k from the conversion cost. Sadly, converting to electric will cause it to lose that beautiful engine noise.To get it to pass inspection, I need to weld in new floorboards and need a new windshield. I don't yet know how to weld.


My dad used to have an Audi TT. He's had that to 145, before the governor kicked in. Amazingly stable at that speed.

[The Toecutter]

I'm not so old that I've forgotten the feeling of invincibility I had as a youngster but seriously a good crash will make you think of these things a little differently. Yah and if someone was telling me this when I was 24 I'd probably nod then laugh it off after walking away. Well now I've had plenty of experiences that have finally proven to me that it isn't always the other guy that stuff happens to, no matter how smart and capable you think you are.

I don't at all feel invincible, not by a longshot... High speed driving shunts, death is seldom instantaneous. Miss one downshift? Miss the apex of the turn going too fast? Lose traction? Arms or legs get fatigued, mid-turn? Every move you make, you're crunching a level IV integral in your mind, without realizing it or consciously running the numbers. Do not falter. Pain shows no mercy. At your dying breath, ravens will first lay claim to you.

I don't even consider myself capable, really. I more or less would rather have fun. If it one day ends my life, so be it. I merely see it as my responsibility that it never harms anyone else except for a willing participant inside the vehicle. If that prospective participant is not 100% willing or able to understand the possible implications of the activity? He or she doesn't participate. Needless to say, it's quite fun baiting the AFT, continuously committing a felony on the open road, and playing with pipe bombs while intoxicated on a myriad of controlled substances.

I've been like this since I was a child, and I will more than likely stay this way. In the future when I'm on my own, I may militantly defend what liberties I have from those who wish to take them. It's my nature.


I do have access to a drag strip, and use it. But it just doesn't compare to an open country road, free of inhabitants, endowned with many beautiful curves and small fluctuations in elevation, and the pure sense of liberty that is felt...

Actually it was pretty moot before too, but in MN/North Dakota there are some really desolate areas where a person can really wring 'er out without jeopardizing anyone else's life and limb... but now if you get caught it'll really cost ya. And there's always them damn deer to consider.

The consequence of living in a society drifting towards a police state... Bureaucrats, corporations, and politicians, lusting for uncompromised control over our lives, our money, and demanding our unyielding faith and obedience, see it fit to punish most severely those activities they deem illegal which pose no risk to others or their property. They justify the existence of such laws merely because such laws exist. A logical fallacy.

Provided the mounted camera can't make out you or your license plate(or you don't have plates on your vehicle for the duration of the run!), and provided a chopper isn't on your *** in under 3 minutes, pursuit is untenable.

Sport bike guys know this and they know it well. So too do sports car guys.(corollary: rare exceptions exist where sport bike guys outrun helicoptors)

Just don't slip up, or Ponch and John will throw the book at you, even if you never hurt anyone or posed any risk to anyone but yourself. Perhaps someone could fire a few bullets in Ponch and John's direction, but that would sink them to their level. Besides, many times Ponch and John are just doing their job, even if they may not agree with it. Like many others, they will trade the tangible liberties of other people or even their own liberties for a temporary feeling of security, an illusion engineered to make them feel good, appease the over-bearing security moms for the sake of 'the children', and be patriotic. After all, it's food on the table, a roof over their head, protection from those evil terrorists that will destroy every last remaining WASP...

"But officer, it's just a forklift motor and a bunch of batteries."

I think the Tempo could get by on two cylinders. Around here there is hardly any city driving so out on the road where people come blasting up behind me, they can just pass if they don't like my pace. My most common "long" trips are 60 miles and 350 miles away. At 52 mph vs 59 mph (my old cruise speed) the time penalties are 10 minutes and 48 minutes- I can handle that. I easily fritter away 10 minutes before going or 48 minutes at breaks on six hour trips so it gets “lost in the noise” anyway.

With a few subtle changes, this would have been a fine automobile. My friend Matt has a 1989 Ford Tempo. It reeks of illegal plants and McDonalds, and he even got stoned in it with Tommy Chong(I have autographed pictures to prove they at least met), but compared to that piece of **** Suzuki I use for a daily driver, it's a Porsche! With a few changes to the rear rake of the car, rear wheel skirts, LRR tires, partial grill block, smooth hubcaps, full smooth underbelly, and updated engine technology, this would have made a fine car. The car's overall profile and dimensions lend itself to the possibility of having excellent aerodynamics without sacrificing stability, storage space, performance, handling, or any other parameter, without adding anything significant to the cost. But it just wasn't to be. But the big automakers don't really care about the finer details; they care about making subpar products with the highest possible profit margins. They answer to investors who demand maximized profits, and not the consumer who demands fuel economy, performance, reliability, and affordability. Advent of the monopoly, the 'free market society' gives the consumer choices: either buy from a selection of uniform products driven into archetypes with similar prices and traits to competitors, or do without. Price discrimination at work.

The Tempo could have very easily been a 50 mpg car with the right touch ups. I'm quite partial to the diesels myself. In my opinion, the only thing it would need after all of the above were done is more power, but not everyone shares my opinion.

Holy O/T batman... but neat, I did like Rush growing up.

Uhm, about the scanguage, okay, I need to find someone in the Vancouver area that has one. I want to try this thing out for 5 minutes. I could sell a hundred if it works.

[MetroMPG]

ScanGauge ... try contacting philmcneal (http://www.gassavers.org/member.php?u=243) on this board. He's in your neck of the woods.

[smartzuuk]

I have pm'd the fellow in Surrey.

[smartzuuk]

Okay, many thanks, I now have a Scanguage I in the smart, and will work on calibrating it over the next few days. Then I will kick some arse on numbers again...

[MetroMPG]

I'm surprised that the smart crowd hadn't discovered the SG prior to this (if I read your earlier post correctly).

Anyway - nice to hear you're equipped. Have fun & report back!

[onegammyleg]

I'm surprised that the smart crowd hadn't discovered the SG prior to this

Maybe they are a bit ...

[philmcneal]

yes that smart car has some potenial! the scangauge actually shows 0.0 LPK when the driver lifts his foot off the accelerator!

[smartzuuk]

Indeed, the smart diesel doesn't use fuel when coasting... !!!

...which more than makes up for for not putting in an auto-stop or kill switch, which isn't really a good idea on a turbo'd diesel, as you want the turbo to cool down before shutting the engine off.

I do turn the engine off after 15 seconds of being stopped, as long as I have 15 seconds more before I need to go - like when there is a train obviously.

You guys just wait til I get my skinnies back on the car and boost the PSI... :eek:

[smartzuuk]

skinnies back on and PSI set at 44

seems I can get 70 mpg US in day to day driving, mixed hwy + city + suburban... partly due to using Scanguage. I loved it so much, I've got a bulk purchase going, and already 35 units are ordered for Canadian smart owners. I'm going to get more in, and have some leftover... under $200 Canadian if anyone from Canada is interested.

[Mike T]

Hi smartzuuk!

Keep the MPG up, because I'm not doing my part for fuel economy.....
