1979 GMC RTS T7W603
The Rapid Transit Series (RTS) bus is a long-running series of transit buses originally manufactured by General Motors (the last generation of that company’s long bus heritage) during 1977, in Pontiac, Michigan, and is currently produced by Millennium Transit Services as the RTS Legend.
First produced in 1977, the RTS was GMC’s entry into the Advanced Design Bus project is the descendant of GMC’s entry in the U.S. Department of Transportation’s “Transbus” project. The RTS is notable for its then futuristic styling featuring automobile-like curved body and window panels. That design has become a classic, though remains more contemporary as that of its predecessor, the GMC New Look which had a curved windshield, but flat side glass and body panels.
