Long-Haul Truck Fleet Applications and Manufacturers

Typically, biodiesel blends can be used in conventional long-haul trucks without engine or vehicle modifications. The same is true for ultra-low sulfur diesel, which model year 2007 and newer diesel vehicles (powered with model year 2007 and newer engines) are required to use.

The availability of true long-haul liquefied natural gas trucks is limited. See the Clean Vehicle Education Foundation's Available Natural Gas Vehicles and Engines (PDF 240 KB) for the most recent list of available heavy-duty natural gas engines. Download Adobe Reader. These engines can be used for various applications. Contact the engine manufacturers to find out which vehicles feature their engines, or contact heavy-duty vehicle manufacturers to learn about the natural gas vehicles they offer. Also see the Vehicle Make/Model Search for information on heavy-duty alternative fuel vehicle availability.

The U.S. Department of Energy previously published the Heavy Vehicle and Engine Resource Guide (PDF 993 KB). Download Adobe Reader. Although it is no longer current, the guide still provides valuable information about the types of heavy-duty alternative fuel engines and vehicles that have been available as well as contact information for key manufacturers and information sources.

Long-haul trucks can take advantage of idle reduction technologies. See the Available Idle Reduction Equipment section and the U.S. Environmental Protection Agency's Available Idle Reduction Technologies page.
