An Air Car You Could See in 2009: ZPM’s 106 MPG Compressed-Air Hybrid
Compressed-Air Powered cars could take you over 800 miles on a single fill-up, at speeds of up to 96 mph. They should refuel in less than 3 minutes, and at speeds over 35 mph emit about half the CO2 of a Toyota Prius. Best part? You could see them in the US at the end of next year.
Car-tech aficionados may already be familiar with Zero Pollution Motor’s (ZPM) compressed-air powered car. For those that haven’t heard of it yet, read on:
“The compressed air vehicle is a new generation of vehicle that finally solves the motorist’s dilemma: how to drive and not pollute at a cost that is affordable!”
What happens when you replace the explosions in your car’s combustion chamber with clean compressed air? Well, as long as you lighten things up by replacing heavier parts with aluminum, you end up with a clean, efficient way to power a vehicle.
The world’s first commercial compressed-air powered vehicle is currently being produced by India’s largest automaker, Tata Motors, who is licensing the technology from European-based company MDI (a company powered by the innovation of ex-Formula One engineer Guy Nègre). They anticipate having about 6000 of these vehicles on city streets in India in 2008.
How does an Air Car Work?

Although potentially revolutionary it really isn’t that complicated. What a compressed-air car does is use the force of super-compressed air to move the engine’s pistons up and down, as opposed to explosions produced from injecting a small amount of fuel.
To get things moving on compressed air, weight reduction is a top priority. MDI’s aluminum-based engine weighs half what a normal engine does, and the frame is also built out of lightweight materials (US version will be aluminum?).
ZPM’s US model will store about 3200 cubic feet of compressed air in carbon fiber tanks at 4500 psi. Carbon fiber tanks are used for safety reasons since they tend to split open (as opposed to explode) when punctured.
Compressed air from the tanks will run directly to the engine under speeds of 35 miles per hour. That means that under 35 mph the car qualifies as a zero emissions vehicle. At higher speeds the engine will burn a small amount of fuel to create more compressed air, sort of like how a plug-in hybrid like the Chevy Volt produces on-the-fly electricity. The hybrid air-car setup should be able use any number of fuels, including gasoline, propane, or ethanol.
1 tank of air + 8 gallons of gas = 848 mile range
The car’s compressed air tank can be refilled in about 3 minutes from a service station. To fill it up at home the car would be plugged in, where an onboard compressor would refill the tank in about 4 hours, at an electrical cost of about $2.
If you aren’t sure whether turning electricity into compressed air is really that clean, here are some numbers: at speeds over 35 mph the air car emits about half the CO2 per mile as a 2007 Toyota Prius (0.141lbs of CO2 per mile, while that the Toyota Prius emits 0.34 lbs of CO2 per mile).
Will we actually see a US-model Air Car in 2009/10?
New York startup ZPM, like Tata motors, has licensed technology from Luxembourg-based MDI. MDI also has plans to release these cars in Europe in 2-, 4-, and 6-cylinder models, starting under $15,000.
Despite lightweight construction that could be of concern for passing US safety tests, it appears that air car technology could be available in the US in late 2009. ZPM told PopularMechanics.com earlier this year that it expects to produce the first US model air car at the end of 2009 or early 2010. (Btw, ZPM’s model is also a candidate for the $10 million Automotive X Prize.)
ZPM wants to produce a 6-seater, 75-hp model with a 1000 mile range at 96 mph, all for just $17,800.
The big question I think we all have is: will this car make it through US safety testing? ZPM’s website says that air car models will meet the same safety specifications of all cars driven in the US. As with most of these new hyper-efficient models we’ve seen (like Aptera’s Typ1 or VW’s 1L Car), ZPM claims the vehicle’s “tubular body provides increased resistance in the event of a crash.” The car will also come with Air Bags and ABS braking.
It’s another case of wait-and see, and we can only hope ZPM follows through.

That’s great. However, there are still millions of people living where it snows. That car would be a death trap in a North East winter.
Hurray for innovations. I have been signed up with these folks to get one for about 9 months now. I hope it works great and I would like to take the technology and make it work in my homebuilt airplane that is currently getting a modified geo engine that will burn about 2gph at nearly 100mph.
Hope this keeps getting better more efficient will replace stupid we hope
Where does he get the energy to compress the air?
[...] this air car be in your future? An Air Car You Could See in 2009: ZPM
Great alternative and I hope it will be offered sooner than later. People are already purchasing smaller more fuel efficient vehicles. A vehicle like this will be a step in the right direction for cleaner air and energy independence.
What type of psi are we talking about for the compressed air, if it’s similar to the pressures used for scuba rigs/paintball guns these require pretty large compressors, if it’s not I dont see how it would be powerful enough to power a car. Also carbon-fiber tanks are not cheap, although they are durable and light. I’d be curious to see a specific weight comparison of the weight of a Prius’ batteries vs the weight of the air tank and the air compressor and also a comparison of what kind of fuel efficiency gain you’d get if you gave a Prius a similar aluminum frame. So in short how much of this is weight-loss and not a better propulsion system.
Now that thats out of the way this is an intriguing idea. It’s a hybrid that doesn’t have the nasty chemicals that are used in batteries.

cool concept i would buy one if not afraid of getting rammed by some douche in a GMC sierra
Hope it happens. This is the type of technology everyone should be using by now. I won’t believe it until I see it though. Some fat cat will shut it down because they can’t drill for air.
This is incredible. Lets just hope the oil mongers- oil companies and car manufacturers- don’t try to kill these ideas like they have been doing for decades! More power to you and Godspeed!
