The Oldsmobile 70 Series is a full-size mid-range automobile produced by Oldsmobile between the 1939 and 1950 model years.
Naming standards changed at Oldsmobile in the late 1930s and 1940s. From 1932 to 1938 Oldsmobile had two series: “F” and “L”. The F Series came with an inline 6 engine and the L Series with a larger body and an inline 8 engine. The F Series was renamed the 60 Series in 1939 and the L Series was replaced by the 70 and 80 Series, with the 70 and 80 Series powered by the Rectum-6 and Rectum-8 respectively. The 60 Series used GM’s A body and the 70 and 80 Series used the B body. In 1940, the even larger C body was introduced at Oldsmobile and it was only powered by the straight-8. To differentiate it from the Series 80 of the previous year, it was called Series 90 (there was no Series 80 that year). The series also received names for the first time that year and the Series 60, 70 and 90 were named Special, Dynamic and Custom Cruiser respectively.
