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.

Two weeks ago I penned a short note to ZPM. I just asked a couple of pertinent questions regarding where their vehicles will be manufactured and whether any prototypes can be seen right now in the U.S. They didn’t reply.
I get the impression ZPM is a couple people in a rented office who put out press releases every six months. They must learn, as Honda and Toyota did a long time ago, that the customer is king.
ZPM: I believe in aircar technology and I’m your future customer. I’d please appreciate a little customer service.
Does this vehicle come with an air conditioner? If it doesn’t, you’ll die in one in Texas in traffic.
Couldn’t we use Hydro power to run turbines with high gear ratios to compress the air? After the Hydro motors pay for themselves, the compressed air would be vitually free. the only cost would be the canisters to store the air. Neary a zero carbon footprint.
Unfortunately this car will never see the light of day. We’ve been hearing about this for the last 10 years, every single one of which we’ve been told that it is just about to hit shelves.
Never going to happen, because its too good to be true, and the world is way too messed up for anything good to happen.
Looks promising but we’ll see how it actually is put out into the market. I’m not going to hold my breath.
This sounds great. we will always need oil to lube things but lets cut the glut.

You people seem to be forgetting the one major problem with these types of cars:
It takes more energy to compress the air then one gets by using the compressed air as an energy source. So in other words, this will worsen our dependence on fossil fuels. It makes more sense to just have it be 100% electric.
Every step of the energy conversion process, something like %30 percent of the total energy is lost. So in using gasoline and electricity to convert air into compressed air, the resultant fuel will have roughly 30% less energy store than the amount that went into making it.
Oil for instance, is an extremely high energy fuel by weight. However, it doesn’t have nearly the amount of energy that went in to making it over the millions and millions of years.
The same thing applies to hydrogen. It takes more energy to create and store the fuel than we get by using it.
It is more sensible to just have 100% electric car.
4,500 psi would be a problem in a crash. A huge problem. Even if carbon fiber tanks “split” they would produce some seriously fast and powerful projectiles. Less mess though, if everything is vaporized.
