Don’t worry, just a little bump - $70 is just around the corner. Short traders just keep making those margin calls, mortgage the house if you have to. Fortunes await you! PO is for pansies and doomers. At $70 short some more ..... it is going back to $22 .... the world is awash with oil ........ reality has nothing to do with it, its all in those charts!!!!!!!!!!

The USA version only gets about 35 mpg city. Not very good considering how small it is.
In the old days a subcompact was cramped and had very little creature comforts. Today, all the new subcompacts are nothing more than full size cars with the front and back chopped off. They have most of the same interior room as a regular compact, but with a tiny engine (hence little hood overhang) and no trunk space. In the case of the Smart they take out the back seat. But they have all the accessories and safety features that adds a lot more weight to the mix than, let's say, an old Ford Fiesta.
One of the drawbacks of building a car shaped like this is it's more dificult to get good aerodynamics as the car becomes more cube-shaped. The drag on the Smart Car I've seen published is 0.34 which is mediocre. On the freeway, the higher drag will take away a lot of the advantages of the weight savings.
The Toyota Yaris has a published Cd of 0.29 which is much better.
So I really think reducing the size of cars quickly reaches a point of diminishing returns and for many, the Smart Car is over that threshold.

I heard of someone who designed and built a compressed-air car that gets about 800-1000 miles on a 10 gallon gas tank. If only the big automakers put all their focus into that technology, we might see some hope for the personal vehicle. _________________ "If humans don't control their numbers, nature will." -Pimentel

Disadvantages:
* Limited range due to available tank technology.
* Using energy to compress air is less efficient than charging a battery with that same energy.
* Less efficient than electric motors.
* Overall efficiency is approximately one third of a comparable electric car
To me the only big advantage of air cars is avoiding the expense of batteries.

The Air car pops up now and then, scams investors off their money and dissapears for again. Rinse and repeat with the next batch of gullible investors.

The main advantage is that they are cheaper to build than electric or internal combustion engine cars, and efficiency is somewhere in between. I wouldn't mind driving around with 80-100 miles per gallon. _________________ "If humans don't control their numbers, nature will." -Pimentel

Why would anyone buy the crippled fuel mileage of the US based Smart car when you can have a Toyota Yaris, a Honda Civic, or similar regular sized car for just a bit more money and get THE SAME FUEL MILEAGE?
The Yaris is actually cheaper than the Smartcar if you get a base model (and compare it to the lowend smartcar, there are 3 smartcar models)
Also, bear in mind you have to put PREMIUM gasoline into the smartcar. With the mpg figures I've seen for the smartcar (41/33 vs the yaris 40/30 (manual trans)) it really makes no sense to buy one.

The Yaris is the "in" car it seems. I've noticed so many on the road around here. That car would get 10mpg more then my current ride, just not sure about parting with the cash. _________________ "Oil is going up because we use too much oil, and the capacity to replace reserves is dwindling"

Don't trust official declared mileage.
Here in the EU car magazines made a huge research into it and there was a scandal: official mileage are almost always 20-30% overestimated.
Before buying a car, check for yourself with a friend already owning it, don't trust what automakers declare.
I have a WV Polo 1400 turbodiesel, with a declared mileage of 67 per gallon, but all I get is 50 maximum... which is OK, but much lower than they say. _________________ **no english mothertongue**

Sure, but what kind of cheap energy will you use to fill that tank with suffiently amounts of compressed air? What kind of losses do you have when compressing air into air tanks? What kind of losses do you have when using that compressed air to propel the car forward? They ain't small, I tell you. The air car isn't even as efficient as a conventional diesel car, say nothing of the air cars miniscule range. Show me the calculations and I'll stand corrected, but until then I'll call it a hoax. _________________ "We cut the earth until it bleeds, rain ashes from the sky

Not really the advantage.
The advantage of the aircar over electric is rapid refueling. Obviously the recharging station needs to consume a lot of energy to compress air (coal or nuke probably, but the idea of using a large air tank at a station to even out wind/solar intermittancy is clever). The biggest problem with electrics right now is the "oh crap, I'm out of power and it will take 2-5 hours to recharge". Advanced batteries or supercaps might take that last advantage away from the aircar.
I would *so* drive a car with a 15 mile range, if there were a rapid recharger at/near a in-range train station (for longer trips) and at/near work. _________________ At 1% annual growth, human bodies will incorporate every gram in the observable universe in approximately 10,170 years.

The auto companies and the government are not serious about increasing fuel efficiency. Auto mileage can easily be increased by 25% or more by raising compreshion ratios. I once had a '71 Vovlo P1800 with a compresion ratio of 12.5:1 that got 43 mpg at 90 mph (my typical driving speed in those days).
Increasing mileage by increasing the compression ratio, increases NO2 output, but not as much as the decrease in fuel consumption would reduce it.
We have again been sold a load of BS by government agencies that are primarily employeed at finding ways to justify their own exisistance, and we are too lazy, and too stupid to bring them to task.
To do that would mean we would have to learn some science and some mathematcs! Lord help us!! Instead we would much rather take the word of some stuffed shirt bureaucrat who doesn't know any sciece or math either.
So much for democracy in a technological society, when the society does not even understand the technology that keeps them alive!

Ditto for my daughter's old VW Golf. Has an onboard computer that tracks mileage, now at 39+, lifetime average, and it has 140,000 miles on it. Summer mileage is 40+, winter a bit less.
Has high compression and wants premium gas. But, old as it is, it will still burn the tires in 3 gears, and run off from a lot of cars that get lesser mileage.
Yup. We got sold a bill of goods on the NO2 thing. I was there, at GM when they were fighting that battle. I drew the first throttle body fuel injection unit they made, while at Delco Electronics, back before 1970.
It gets really disgusting to listen to some of the myths about what has gone on in the US auto industry. I see a lot of misinformation even here on that topic. But I'm tired of it, and refuse to try to bring people up to speed any more. Let 'em live with their bullshit dreams.
