The above links are to a list of new, factory-built AFVs that are fueled by those fuels. Simply click to see the current vehicles you can purchase that run on those fuels. Some are flex fuel, some are bi-fuel and some are dedicated (see more on these definitions here).

There are also opportunities to purchase used AFVs. One big example is the U.S. General Services Administration (GSA), which held auctions at over 50 different locations nationwide last year, selling over 35,000 total vehicles and about 1,400 AFVs. They expect to sell about 3,200 AFVs this year through auctions. More info on GSA auctions can be found here: http://www.autoauctions.gsa.gov/afv. In addition, several sources of information exist on the resale of AFVs. One such source is the Alternative Fuel Data Center (AFDC), which has a page that addresses "The Used Alternative Fuel Vehicle Resale Market," and where an article can be found on "Successes and Challenges in the Resale of AFVs".

One other note on GSA auctions. It appears that there is one local reseller for GSA vehicles, and that is Chattanooga Auto Auction. Their Web site tells when GSA auctions are (next one is Tuesday, October 22nd), and provides information on the GSA vehicles expected to be auctioned off that day, as well as directions to the facility. Their auctions are held every Tuesday, with GSA vehicle auctions only occuring approximately 2-3 times per year. Check the Web site first; if you have other questions, contact Larry Hammill at 423-499-0015.

In addition to the new and used factory-built vehicles, conversion companies exist that can convert either new or used vehicles from running on gasoline or diesel to an alternative fuel. The following link is to an AFDC page that provides the names and contact information for companies that convert vehicles (organized by fuel type): https://afdc.energy.gov/afv/conversion.shtml.
That page also contains a conversion Question & Answer section.


> VW Touareg and Jeep Liberty CRD Biodiesel - light-duty diesel vehicles sold in the U.S.
These are vehicles that it is possible to run biodiesel in, since any diesel vehicle can run biodiesel. You'll most often see blends like B20 in use in such vehicles, but in certain areas municipalities and individuals alike are running higher blends in their diesel vehicles, including B100 (example - link to article about City of Berkeley converting entire fleet to run B100!).

> Hydrogen (Fuel cell vehicles)

No fuel cell vehicles (FCVs) are publicly available yet, however, some automakers are making quicker progress toward such availability than others. For example, Toyota is building about 20 FCVs that will be tested in Japan and the U.S. later this year. Even with this jump-start, Toyota thinks it will be 2010 before full-scale commercialization of FCVs will begin.

> Types of AFVs
Bi-fuel:  The vehicle can operate an either of two fuels, and has a switch that must be flipped to choose which fuel you want to run on. The vehicle has two tanks, one to hold each different type of fuel. The most common examples of bi-fuel vehicles are those that can run on either 1) gasoline or propane or 2) gasoline and natural gas.

Flex fuel:  The vehicle can operate on either gasoline or E85 (ethanol), and both fuels are feed into the same tank on the vehicle (the vehicle has only one tank). You can fill-up with either fuel at any time -- the fuels can be mixed in any proportion to run the vehicle. These types of AFVs have fuel oxygen content-sensing equipment on-board that alters engine timing based on the sensed oxygen content of the fuel coming into the engine. The sensing equipment is mostly electronic and works constantly (when the vehicle is on).

Dedicated:  The vehicle can operate on only one fuel, and has only one tank. There are dedicated propane, natural gas, electric, hydrogen and gasoline vehicles (the car you drive right now is a dedicated fuel vehicle, it just runs on the wrong fuel -- gasoline). ;-)
