Oldsmobile Series 60

The Series 60 "Special" is a full-size car made by Oldsmobile from the 1939 through the 1948 model years. It was their entry-level model using the GM "A" body platform, giving Oldsmobile an entry-level product with more standard features that would be optional on Chevrolet and Pontiac vehicles using the same platform. Initially, the engine size used was the company's flat head 6 cylinder, while senior models would use the flat head 8 cylinder. For marketing purposes, the Oldsmobile Series 60, or the Oldsmobile 66, took advantage of the national highway U.S. Route 66 established in 1926. It was with this generation that all GM vehicles experienced increased width dimensions to accommodate three passengers on the front bench seat and an additional three passengers on rear bench seat installed vehicles. This was accomplished with the deletion of running board thereby adding additional room inside the passenger compartment and upgrading the floor mounted gearshift to a steering column installed transmission gear selector for the Hydramatic automatic transmission.
