On June 21, 2006 the Environmental Protection Agency unveiled the world's first hydraulic hybrid delivery truck in Washington D.C. The EPA hybrid features a hydraulic drivetrain that replaces a conventional drivetrain and eliminates the need for a conventional transmission. 
Ford Motor Co. is dropping its pledge to build 250,000 gas-electric hybrid cars per year by 2010.
Instead, the No. 2 U.S. carmaker will focus on other fuel-saving technologies in a switch that has provoked environmentalists, The Washington Post reported.
This hydrogen fueled bus is one of four in use in the United States. At $3.1 million, the buses are still too expensive for transit agencies to run as a fleet. A diesel bus costs about $360,000.
Utilizing fuel cell technology, the hydrogen-fueled electric fuel cell bus has no emissions; and according to the fuel cell manufacturer, UTC Power, you could drink right out of the tailpipe, as the only byproduct is water.
BP PLc and DuPont are partnering to create biofuel from sugar beets manufacturing a product called biobutanol.
Biobutanol, a rival to the corn-based fuel ethanol, can be made from a range of common crops, such as sugar cane or sugar beet, corn, wheat or cassava, and has the potential to be blended into gasoline at higher concentrations than existing biofuels without the need to retrofit vehicles. It can be used in existing fuel distribution pipelines, offers lower emissions and would give consumers more miles per gallon, DuPont officials said. http://money.cnn.com/2006/06/21/news/companies/energy_biofuels.reut/index.htm
Available this fall, the Saturn VUE Green Line takes a different approach to hybrid technology. Saturn will build a mild hybrid that will only add a couple thousand to the sticker price over a non-hybrid VUE, but will not provide as much fuel savings as some hybrids now on the market.
A fuel station owner in San Diego is taking fuel diversity seriously. Not listed on the signboard is compressed natural gas. 
The station is the only one in the U.S. that sells such a wide range of fuels. And it's the only facility on the West Coast where private citizens can buy E85, a mix of 85 percent ethanol and 15 percent gasoline that can be used in a number of models that already roll from American assembly lines.
North American drivers of the Toyota Prius get to stare at a blank plate that is a functional switch in the European market. Why can’t we have one?
Ford is developing simple approach to regenerative braking and storing energy. The F-150 Hydraulic Hybrid is expected to launch in August 2008.
