The GM Futurliners were a group of stylized buses designed in the 1940s by Harley Earl for General Motors. They were used in GM's Parade of Progress, which traveled the United States exhibiting new cars and technology. The Futurliners were used from 1940 to 1941 and again from 1953 to 1956. A total of 12 were built, and 9 were still known to exist as of 2007.
