The results obtained from the 40-vehicle fleet of methanol-fueled Escorts in service since 1981 are reviewed. These results provided the basis for an upgraded vehicle built on the production line. A total of 587 vehicles were built, including five advanced technology vehicles with more stringent emissions goals at equivalent thermal efficiency. Vehicle configuration, fuel and oil specifications, and emission, fuel economy and performance data are discussed. One of the major challenges when developing the vehicle was the selection of fuel system materials compatible with methanol. A follow-on program to find cost reduction solutions is underway.
