Heavy-Duty Vehicle and Engine Data Collection Methods

To maintain the Heavy-Duty Vehicle and Engine Search tool, the National Renewable Energy Laboratory (NREL) gathers information about alternative fueled medium- and heavy-duty vehicles, engines, and hybrid propulsion systems from specifications posted on websites of original equipment manufacturers as well as information provided by vendor representatives. Vehicle specifications are updated as new models are released and/or updated. NREL conducts a comprehensive update of this database annually.

Caution: The Alternative Fuels Data Center recommends users check with their local dealers for more specific vehicle information before making purchasing decisions.
