The Mobilgas Economy Run: A History of the Long Distance Fuel Efficiency Competition, 1936-1968

The Mobilgas Economy Runs were annual competitions in which new American production automobiles vied not for speed, but for fuel economy—even as the industry was turning out bigger, more powerful cars year by year. This first complete history of the runs (including the predecessor Gilmore Economy Runs) follows each year’s competitors day by day, covers some aspects not reported at the time and features a wealth of photographs. It includes coverage of the related Mobil Mileage Rally, held for imported cars from 1958 through 1961. Complete results for all of the competitions are provided in an appendix.
