Toyota engineers have set a potential record of 80.3 PMH for a car that's powered entirely by air. However, you're more likely to see the technology incorporated into a hybrid than a standalone vehicle.
The air functions like steam in a steam engine - by expanding and driving pistons, which ultimately moves the vehicle. A tank mounted in the back of the car provides its compressed air “fuel,” propelling it to speeds up to 129.2 kilometers per hour.
Toyota’s engineers are seeking certification from Guinness World Records for the world’s fastest air-powered car, Japan Broadcasting Company reports. The test run happened on Sept. 9 in Shirosato Japan. The tank was filled using a conventional air-conditioner compressor manufactured by Toyota.
Here's a video of it in action:
The aforementioned “steampunk” reference is relevant, because inventors have been tinkering with air-powered vehicles for nearly two centuries. Range has always been an issue due to the low energy density of compressed air; Toyota's prototype can only go 3.2 KM before running out of "steam."
So, don’t except to see an air powered car in your Toyota dealership’s lot anytime soon – this was a proof of concept. You may, however, one day be able to purchase a hybrid vehicle that is partially air powered.
Researchers in Sweden have recorded a 60 percent increase in fuel economy by using a compressed air hybrid engine. They achieved that efficiency by retrofitting existing internal combustion engines and capturing energy from braking.
This goes to show that what’s old is in a way new again. The technology still has to be scaled to a street legal engine, but the economics of a hybrid drivetrain sans costly batteries could carry it forward.

toyota engineer have done a great job with all of the things yet produced and I am positive this is going to be a success as well. http://www.national.co.uk/branch-50-Macclesfield.aspx
science is really progressing alot that we have now discovered the air filled car i'm quite hppy by learning about it. http://www.sellyourcarfast.com.au/sell-my-car-fast/
air system might be the future, to powered cars. Science we are running out of resources. But is it possibly to use normal air?
I hope for the best:) What i do know is there in NO reason we should still be using gas i wish the scientists would stand up to the oil companies for the rest of us. We are actually having a discussion about this..... http://www.mforums.org/showthread.php?tid=101
Oops.... vid has been pulled. (at least from your link). ""?????????"????????????????????????..." This video is no longer available due to a copyright claim by NHK. Sorry about that.
This is just one of 3 air cars under development or already being sold in France. http://news.bbc.co.uk/2/hi/europe/2281011.stm
None of the car companies seem to be interested in my idea. I know how to make an all-electric powered vehicle that NEVER will need to be plugged into electricity and will never use a drop of gas. Not nuclear or sun-powered, either. America, nor the world, would have to be held captive by the oil companies, no fumes, and no global warming from these vehicles. If any car company wants to become #1 in the world, contact me and we'll talk. I don't think I am a quack.
I'd like to see more about the ICE-pneumatic hybrid concept. Does all the energy to compress air come from braking or does the engine run the compressor while the car is stopped? Would the tank be pre-filled by using house current like a plug-in hybrid?
How do energy/volume and energy/weight of compressed air compare with chemical batteries? If problems of moisture and adiabatic efficiency can be solved it certainly sounds like a more ecologically benevolent way to store energy than nasty chemicals.
THIS TIME, I was NOT deceived by the lie in the headline (the sub-head I saw, that said this car was powered "entirely" by air). And that's because I have been so deceived before, by this site. Maybe you guys need to learn what English words mean, before being allowed to use them on the unsuspecting public. Let's be oh-so clear. The air was used to TRANSFER power from the "conventional air-conditioner compressor" to the car's air engine. The "powered by" part of the equation is called "electricity." And please don't go away thinking that my criticism is mere fluff. The misrepresentation of science is in fact one of the major factors in science's low approval ratings among those who do NOT have the nonsense filters I've developed over time. That is a problem that COULD be better dealt with, if sites like this took better care in marketing scientific concepts -- without alluding to TRUE fluff like "steam punk" to do it.

What you say makes sense, even to a lay person like me. Clearly, there must be an expenditure of energy to compress air to the requisite 4,000 plus pounds per square inch needed to drive the 'air engine'. That compression costs energy, time and money. Then, the 'stored' air in the vehicle's air cylinder must be moved out of the cylinder and through the 'air engine'. In essence, then, the 'air' is being used as an energy and transfer' medium. So, can you tell me what the costs are, in some comparative way, to compress air the the required pressure? Jeff Garrett, Boise, Idaho
