Abstract:The South Coast Alternative Fuels Demonstration, called CleanFleet, was conducted in the Los Angeles area from April 1992 through September 1994. The demonstration consisted of 111 package delivery vans operating on five alternative fuels and the control fuel, unleaded gasoline. The alternative fuels were propane gas, compressed natural gas, California Phase 2 reformulated gasoline (RFG), methanol with 15 percent RFG (called M-85), and electricity.
Fuel economy estimates were obtained from statistical analyses of fuel consumption records kept on the 111 CleanFleet vans while being operated by FedEx in normal package delivery service. At each of four sites, either 20 or 21 vans provided by one to three vehicle manufacturers (Chevrolet, Dodge, and Ford) were operated using one of the liquid or gaseous alternative fuels. Three control vehicles from each manufacturer were also included at each of these sites. Two electric vehicles (EVs) with lead-acid and with nickel-cadmium batteries on G-Van platforms were operated at the fifth site. Relative fuel economy, compared to unleaded gasoline, was determined for each combination of alternative fuel and vehicle manufacturer. The results are compared with relative fuel economy estimates determined from the CleanFleet dynamometer emissions tests.
