How much does an alternative fuel vehicle cost?

Well, it really depends on the type of vehicle you choose, and how long you plan to keep it:

• Hybrids can cost several thousand dollars more than a regular car. While they still use gasoline, their fuel economy and potential reduced maintenance will actually save money over the life of the car. Here's a look at the current hybrid models.
  
  
• Flex-fuel vehicles (FFVs) (those that burn E85) are comparable in cost to similar gasoline cars, and E85 tends to cost less than gasoline, though prices can vary greatly across the United States. Take a look at what's available in current model FFVs.
  
  
• Any diesel vehicle can use biodiesel, so no special vehicle is necessary. In general, diesel vehicles cost more than their gasoline counterparts though they generally deliver better fuel mileage and they have a reputation for durability and long life. The cost of biodiesel is comparable (sometimes less) than petroleum diesel fuel. See what's available in current model diesels and biodiesels.
  
  
• A propane or natural gas vehicle's price tag can be several thousand dollars higher than one powered by gasoline, yet they offer reduced engine maintenance, longer service life and higher fuel economy that can offset their greater initial cost. An added bonus: The price of the fuel tends to be lower than gasoline. Here's what's currently available in natural gas and propane vehicles.
  

Some vehicles may also quality for tax rebates and incentives. The United States Department of Energy database helps you stay up-to-date on these offerings.
