Yes - a car that runs on air! Compressed air, that is.

And they have partnered with Tata Motors to develop this. Pretty amazing technology - lets see when it is in full production.

MDI CAT´s compressed air technology cars.

MDI introduces compressed air vehicles to the market.


MDI has developed a high performance compressed air technology. When it is compared to traditional gasoline powered engines, MDI´s engine is far superior in terms of energy used and thermodynamics.

An overview of the air car
The technology that MDI vehicles use is not new, in fact it had been around for years. Compressed air technology allows for engines that are both non polluting and economical. After ten years of research and development, MDI is prepared to introduce its clean vehicles onto the market. Unlike electric or hydrogen powered vehicles, MDI vehicles are not expensive and do not have a limited driving range. MDI cars are affordable and have a performance rate that stands up to current standards. To sum it up, they are non-expensive cars that do not pollute and are easy to get around cities in.


Two technologies have been developed to meet different needs:
Single energy compressed air engines
Dual energy compressed air plus fuel engines
The single energy engines will be available in both Minicats and Citycats. These engines have been conceived for city use, where the maximum speed is 50 km/h and where MDI believes polluting will soon be prohibited. It is already possible to see examples of this in some places, such as London, where if you want to enter the city center with gasoline powered vehicles, you must pay a fee.

The duel energy engine, on the other hand, has been conceived as much for the city as the open road and will be available in all MDI vehicles. The engines will work exclusively with compressed air while it is running under 50 km/h in urban areas. But when the car is used outside urban areas at speeds over 50 km/h, the engines will switch to fuel mode. The engine will be able to use gasoline, gas oil, bio diesel, gas, liquidized gas, ecological fuel, alcohol, etc.

Both engines will be available with 2, 4 and 6 cylinders, When the air tanks are empty the driver will be able to switch to fuel mode, thanks to the car's on board computer.

the concept sounds interesting....
..imagine the black smoke spewing buses , cars and rikshaws in aamchi mumbai with such compact, non polluting vehicles :)

dont like the look of it though ...
if anything...it looks like a toy.

Interesting concept. Cost effective too. Like inflating your tyres periodically.

I suppose the car body is plastic (ABS) instead of metal to make it lighter.

Great... hope they can bring this out in mass production before my car goes phut...

A plastic body, Cooldool pai:confused:... cars are made of metal for reasons, if I am not mistaken... specifically to protect human life in accidents. Will plastic be able to do that:confused:

Fiber glass / ABS cars have been in production for a while now. As long as there is a sturdy frame, the sheet is just a covering.

I think this could do wonders especially for cities like Bombay, Delhi, Bangalore, Hyderabad, Madras etc. Cheap and pollution free!

World's First Air-Powered Car: Zero Emissions by Next Summer in India

Great....this will be a big asspain for arabi Mulaah....oil price will come to the bottom once india will start mass production of such Car.:up:

India’s largest automaker 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 in August of 2008.

Barring any last-minute design changes on the way to production, the Air Car should be surprisingly practical. The $12,700 CityCAT, one of a handful of planned Air Car models, can hit 68 mph and has a range of 125 miles. It will take only a few minutes for the CityCAT to refuel at gas stations equipped with custom air compressor units; MDI says it should cost around $2 to fill the car’s carbon-fiber tanks with 340 liters of air at 4350 psi. Drivers also will be able to plug into the electrical grid and use the car’s built-in compressor to refill the tanks in about 4 hours.

Of course, the Air Car will likely never hit American shores, especially considering its all-glue construction. But that doesn’t mean the major automakers can write it off as a bizarre Indian experiment — MDI has signed deals to bring its design to 12 more countries, including Germany, Israel and South Africa.

Is this for real? Does it go atleast 30 km per hour?

According to a news story on Yahoo a couple weeks ago:

The air car can tool along at a top speed of 35 mph for some 60 miles or so on a tank of compressed air, a sufficient distance for 80% of consumers to commute to work and back and complete daily chores.

This is nothing new....this concept has been around as is used in running air driven pumps (for example in handling explosive fluids) where use of electric motor may be hazardous:D

Many special purpose vehicles in industry have hydraulic/pneumatic motors..this is just an extension of the same:D

Battery powered vehicles have lot of scope in India. In India the average speed is not more than 25km/hr in cities. So Max speed of 50 Km/Hr won't hurt much. But Indian Government will promote alternative energy powered vehicles slowly only because most of petrol pumps/gas agencies/vehicle service stations are owned by politicians or their affiliates and Government cannot make them redundant so suddenly. So it will take some time in india although desperately needed in India. Also Govt will not appear to be reducing its dependency on Middle East Oil because of Vote Bnak politics.

BTW famous Poor,Socialist leader and Former Prime Minister Chandrashekhar has some 300 Petrol Pumps,did any body knew that :)
