The Oldsmobile Series 70 is a full-size midrange automobile produced by Oldsmobile between the 1939 and 1950 model years.[2][1] Oldsmobiles of this time period were in an upwardly-shaded "middle" position in GM's hierarchy of automobile brands. Chevrolet and Pontiac were the budget priced models, while Buick and Cadillac were the high-end brands. GM would share their "A" body platforms between Chevrolet and Pontiac, and midrange "B" body on Oldsmobile and Buick, while leaving mainstream Cadillacs and senior Oldsmobiles and Buicks (such as the Oldsmobile 98 and Buick Roadmaster and Limited), and even the Pontiac Streamliner, on its top production luxury "C" platform. Leaving ifs largest and most prestigious D platform to senior Cadillacs and the 1936–1942 Buick Limited.

Competitors from Ford's Mercury and Chrysler's DeSoto brands would give customers a choice to have Oldsmobile levels of luxury, while not paying as much as a comparable Olds. GM would discontinue the budget Oldsmobile Series 60 in 1949 and the Series 70 in 1950, while introducing the Oldsmobile 88 in 1949 to push Oldsmobile upmarket and leaving the lower priced market position to Chevrolet and Pontiac.
It was with the 1940s on that GM vehicles experienced increased width to accommodate three passengers each on front and rear bench seats, accomplished by deleting running boards and moving the floor mounted gearshift to the steering column, including the Hydramatic automatic transmission.[1]

Naming standards were in flux at Oldsmobile during the late 1930s and 1940s. From 1932 through 1938 Oldsmobile had two series: "F" and "L". Series F came with a straight-6 engine and Series L came with a larger body and a straight-8 engine.[1] Series F was renamed Series 60 in 1939 and Series L was replaced with the Series 70, with the two Series being powered by the straight-6 and the straight-8 respectively. The Series 60 used the GM A-body and the Series 70 used the B-body.
In 1940 the even larger C-body was introduced to Oldsmobile and it alone was powered by the straight-8. In order to differentiate it as Oldsmobiles senior level vehicle it was named the Series 90 while remaining below the Buick Special. The series were also given names for the first time that year with the Series 60, 70, and 90 being called the Special, Dynamic, and Custom Cruiser respectively. The Hydramatic transmission, a fully clutchless automatic, debuted in the 1939 model year for 1940 Oldsmobiles.[1]

In 1941 both straight six- and straight eight-engines were offered on each series, so to differentiate between the two the second digit was used to denote the number of cylinders, so the Dynamic 70 was replaced with the Dynamic 76 and 78, and the Custom Cruiser 90 was replaced with the Custom Cruiser 96 and 98. In 1942 sales literature started referring to the Series 70 as the Dynamic Cruiser 76 and 78, and Oldsmobile dropped the six cylinder Series 90 model, leaving only the Custom Cruiser 98. [1]
Production was delayed from 1942 until 1945 due to World War II. To celebrate the company's 44th anniversary, all limited production 1942 autos received a small "B-44" badge on their grille.[3]
In 1946 the Dynamic Cruiser Series 70 was Oldsmobile's mid-priced model, and offered both a 2-door Club Sedan and 4-door Sedan.[4]
Electrical equipment was modest as the cars of this time only used a 6-volt system.[4] The standard equipment offered Bedford cord or broadcloth upholstery, front seat retractable center armrests, rubber floor mats, painted woodgrained instrument panel, dual sun visors, dual electric windshield wipers, and an automatic choke for the carburetor for easier starts for a cold engine.[4] The DeLuxe trim package came with carpeted inserts in the rubber floor mats, a deluxe instrument with full gauges, a retractable center armrest for the rear seat, the E-Z-I anti-glare rear view mirror and an electric clock.[4] the Standard Series 70 had 16" wheels while the DeLuxe had 15" wheels as standard equipment.[4]
Some optional equipment included a choice of a 6-tube or DeLuxe 7-tube radio, electric clock, plastic steering wheel, rear window wiper for both sedans, and auxiliary driving lights.
List price for the Dynamic 70 4-door Sedan was US$1,568 ($25,283 in 2024 dollars [5]). with 25,528 units sold. The Dynamic 70 DeLuxe 4-door Sedan sold for US$1,678 ($27,057 in 2024 dollars [5]), with 5,118 sold.[4]
1947 was Oldsmobile's fiftieth anniversary and other than some new two-tone exterior paint options, the standard and optional equipment and features were carried over from previous years. A heater and windshield defroster was added to the options list for US$32 ($451 in 2024 dollars [5]). New branch assembly locations were added at Atlanta and Wilmington.
The Dynamic Cruiser series proved Oldsmobile’s most popular, with 38,152 2-door Club Sedans and 30,841 4-door Sedans were built, more than the Special 60 Series or the larger Custom Cruiser 98.[4] The Dynamic 76 was produced in Australia with fewer than 120 thought to have been produced during 1947.
In 1948, when the Series 60 was renamed the Dynamic the "Cruiser" tag was dropped from the Series 70 and it was once again named the Dynamic 76 and 78.

The all new postwar Futuramic styling that had debuted on the C-body Oldsmobile 98 in 1948 was brought to Oldsmobile's 1949 A-body, which it also shared with Pontiac and Chevrolet. The new name Seventy-Six, with the numbers now spelled out, became Oldsmobile's entry-level model with the discontinuation of the Series 60. Its wheelbase grew to 119.5 inches (3,040 mm), and the car was only available with the Oldsmobile straight-6 engine.[7]
The straight-8 78 model was retired with the 1949 introduction of the new Oldsmobile overhead-valve Rocket V8 powered 88, which absorbed the 78’s “Futuramic” A-body platform shared with the Seventy-Six.
In its final year, the 1950 Seventy-Six continued to offer the DeLuxe trim package (also available on the station wagon), while the Holiday hardtop coupe (produced by welding a steel roof onto the Seventy-Six convertible)[4]was briefly offered. Only 144 standard coupes and 394 with the DeLuxe trim package were sold, at a list price of US$2,108 ($27,550 in 2024 dollars [5]). This model is particularly rare today, as it was the only time Oldsmobile offered an upscale hardtop body style with a six-cylinder engine.[4]
The Seventy-Six was available in the following body styles:
- Station wagon
- Convertible
- Holiday hardtop coupé (2-door)
- Club coupé (2-door)
- Club sedan (2-door fastback)
- Town Sedan (4-door fastback)1949 Only
- 2 door Sedan (2-door)1950 only
- 4 door Sedan (4-door)
