Sorry to disappoint. Took the title from the name of the car company.
Car powered by compressed air. Pretty cool stuff. The web page I quoted has a pic.

India's largest automaker Tata Motors is set to start producing the world's first commercial air-powered vehicle. The Air Car, developed by ex-Formula One engineer Guy Nègre for Luxembourg-based MDI, uses compressed air, as opposed to the gas-and-oxygen explosions of internal-combustion models, to push its engine's pistons. Some 6000 zero-emissions Air Cars are scheduled to hit Indian streets by August of 2009.
The Air Car, called the MiniCAT could cost around Rs. 3,50,000 ($ 8177) in India and would have a range of around 300 km between refuels. The cost of a refill would be about Rs. 85 ($ 2).
The MiniCAT which is a simple, light urban car, with a tubular chassis that is glued not welded and a body of fiberglass powered by compressed air. Microcontrollers are used in every device in the car, so one tiny radio transmitter sends instructions to the lights, indicators etc.
There are no keys - just an access card which can be read by the car from your pocket. According to the designers, it costs less than 50 rupees per 100Km (about a tenth that of a petrol car). Its mileage is about double that of the most advanced electric car (200 to 300 km or 10 hours of driving), a factor which makes a perfect choice in cities where the 80% of motorists drive at less than 60Km. The car has a top speed of 105 kmph. Refilling the car will, once the market develops, take place at adapted petrol stations to administer compressed air. In two or three minutes, and at a cost of approximately 100 rupees, the car will be ready to go another 200-300 kilometers.
As a viable alternative, the car carries a small compressor which can be connected to the mains (220V or 380V) and refill the tank in 3-4 hours. Due to the absence of combustion and, consequently, of residues, changing the oil (1 litre of vegetable oil) is necessary only every 50,000Km.] The temperature of the clean air expelled by the exhaust pipe is between 0-15 degrees below zero, which makes it suitable for use by the internal air conditioning system with no need for gases or loss of power.
 
It's an interesting technology.

One thing I always wonder, why is every ultra-efficient car made to look like a rolling turd econo-box?

Consumers of 'green' vehicles won't feel smug enough for saving the planet unless they martyr themselves with an ugly car?

Guess you have never seen the Tesla Roadster:p

Oh yeah, It'll go 0-60 in under 4 seconds...and it's all electric:D
 
What was wrong with the VW Bugs that had a big wind-up key on the back ??

Screw the planet. For that kind of mileage, I don't care if it runs on baby harp seal pelts and looks like Uncle Fester's ass.

And it is over $100,000 with a 1 year wait, 1 year if you pay 50%percent deposit up front that it...More interesting to me would be the same electronics offered in an affordable kit form that could be retrofitted to an existing car. Imagine buying a Miata with a blown engine for scrap prices then making an electric out of it.

Exactly. There's no reason in the world why the "tata" technology can't be placed into a pretty car.

I wouldn't drive anything that looks like an Air Car / Prius / Smart Car if they were free and had infinite MPG... You think life's too short for an ugly knife, it's even shorter when it comes to ugly cars.
 
seriously, i wonder how much energy and effort go into actually compressing the air used for the power source
when you factor in the electricity and fuel used to generate it, is it any more efficient than a normal car?
 
No, of course not. The advantage is you don't have to get that energy from burning gasoline in an internal combustion engine. Every other way of getting energy is cheaper and less polluting than that.
 
The thing about electric cars and that stuff is that it's more efficient to produce TONS of electricity using TONS of resources or Uranium, your choice than it is to produce small amounts of energy with small amounts of resources.

That being said electric motors destroy gas in terms of speed and acceleration.

On a side note, I was thinking (after seeing a Prius with a ISAVGAS license plate) about purchasing myself either a rolling launch platform from Nasa or an M1 Abrams Tank and getting a plate that says "GASGUZLE".
 
Turn it into a large 4x4 truck and make it more powerful and then I'll be interested. Until then I have no use for it where I live.
 
No, of course not. The advantage is you don't have to get that energy from burning gasoline in an internal combustion engine. Every other way of getting energy is cheaper and less polluting than that.

Lots of electricity is produced by coal. I know that the coal companies have made efforts to make coal a cleaner burning fuel, but I guess it still doesn't sit right with me on an emotional level. Take all the pollution in China due to coal plants. Is it something that we want to go back to?

I'm not trying to be an a**, I'm genuinely curious.
