The General Motors PD-4501 Scenicruiser was a 43 passenger Parlor series coach built from 1954 to 1956 in the United States. All 1000 were built exclusively for Greyhound. Power was provided by two Detroit Diesel 4-71 engines driving through a fluid coupling. This configuration proved to be unsuccessful and the 979 remaining buses were rebuilt with Detroit Diesel 8V71 engines and 4-speed manual Spicer transmissions during 1961 and 1962 by the Marmon-Herrington Corporation.

The PD-4501 Scenicruiser was the result of five years of effort based on a design by Raymond Loewy. Originally conceived of as a 35 foot bus, Greyhound used a tandem-axle, 40 foot prototype called the GX-2 to successfully lobby for the lifting of restrictions against operation of 40 foot buses.

Originally, the design prototype for the Scenicruiser was a double decker, with access from the first level; and the driver would look to the road from the second level. However, it was soon decided that it would be a split-level instead, with a lower level containing the driving console and 10 seats behind it, and the upper level containing 33 seats. This arrangement also allowed a baggage compartment underneath the second level, while providing 360-degree view for the upper level. A lavatory was located on the rear of the first level. The Scenicruiser was equipped with air-ride suspension and was air conditioned.
