State of Texas Fleet: LPG Pickup Trucks

Photo of Pickup TruckThe U.S. Department of Energy (DOE) launched this project to determine and make available data on the performance, reliability, and costs of light-duty alternative-fuel vehicles (AFVs) operating in fleet service. The University of Texas at Austin, in cooperation with the Texas Department of Transportation (TX-DOT), collected data over a period of 18 months from a group of 1996 Ford bi-fuel propane F-150 pickup trucks. These bi-fuel vehicles can be operated on either propane or gasoline, but not both at the same time. Thirty-five vehicles were studied: 31 bi-fuel propane F-150s, and four gasoline-only F-150s.

Two TX-DOT districts, Houston and Corpus Christi, participated in the project. Each district provided access to maintenance records and operating data from the vehicles. The University of Texas handled data collection and submission, as well as the detailed analysis (in coordination with Advanced Vehicle Testing Activity technical staff).
