Realworld Fuel Economy Testing - The Sea to Sea Econorallye II 810834
Eight fuel efficient vehicles traveled across the continental United States in the 1980 Sea-to-Sea Econorallye II. Each vehicle participating in this fuel economy rallye was evaluated in controlled testing for emissions, performance, and economy. In addition, “real-world” fuel economy was measured for each vehicle for the whole of the 6500 kilometer rallye route. The most fuel efficient vehicle in the rallye achieved 2.693 litres per hundred kilometers fuel consumption of diesel fuel (87.3 mpg), while transporting two passengers across the United States.
