Chronology
Predecessor Oldsmobile G-Series 70 [1]
Successor Oldsmobile Cutlass

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 unusual "middle" position in GM's hierarchy of automobile brands. Chevrolet and Pontiac were the budget priced models, while Buick and Cadillac were the luxury brands. GM would share their "A" body platforms between Chevrolet, Pontiac, and "B" body on Oldsmobile and Buick, while leaving Cadillac on the senior "C" platform. Oldsmobiles were then branded as "luxury level" Chevrolet's and Pontiac's, while Oldsmobiles using the "B" platform were "budget priced" Buicks and Cadillacs.

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 for a comparable Oldsmobile. GM in later years would discontinue the Series 70 and the budget Oldsmobile Series 60, and introduce the Oldsmobile 88 to push Oldsmobile upmarket, giving Chevrolet and Pontiac a better market position for a lower price. 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.

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 Series 70 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 1940 model year. [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. In 1942 sales literature started referring to the Series 70 as the Dynamic Cruiser 76 and 78. [1]

Production was delayed from 1942 until 1945 due to manufacturing efforts being devoted to World War II defense production. To celebrate the company's 44th anniversary at the time, all Oldsmobiles were installed with a small badge on the grille with "B44" attached. This was not a model designation. [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, and the second number in the series designation continued to identify if it had a straight six- or straight eight-cylinder flat-head engine. [4] Some of the 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. Prices listed for the Dynamic 70 DeLuxe 4-door Sedan were US$1,678 ($25,181 in 2022 dollars [5] ) and 5,118 were assembled while the Dynamic 70 4-door Sedan was much more popular, selling 25,528 with a listed price of US$1,568 ($23,531 in 2022 dollars [5] ). [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] Buyers who chose the DeLuxe trim package were given 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] Curiously, the Standard Series 70 had 16" wheels while the DeLuxe had 15" wheels as standard equipment. [4]

1947 was Oldsmobile's fiftieth anniversary and other than some new two-tone exterior paint options, the standard and optional equipment and features remained carryover from previous years. A heater and windshield defroster was added to the options list for US$32 ($419 in 2022 dollars [5] ). New branch assembly locations were added at Atlanta and Wilmington. Due to the American public taking the opportunity to purchase new vehicles to replace cars kept in service due to WWII production suspension, 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 post-war Futuramic styling that had been introduced to the C-body Oldsmobile 98 in 1948 was brought to Oldsmobile's A-body which it now shared with Pontiac and Chevrolet in 1949, and the new name Seventy-Six, with the numbers now spelled out, became Oldsmobile's entry level model when the Series 60 was discontinued. The wheelbase was now 119.5 inches (3,040 mm) and was only available with the Oldsmobile straight-6 engine. [7] The previous 78 model was retired with the 1949 introduction of the Oldsmobile 88, which shared its new Futuramic A-body platform with the Seventy-Six but was equipped with the new overhead valve Rocket V8. The new word from 1948 "Futuramic" identified an Oldsmobile as the Dramatic Design of the Future, Beauty with Design and Styling with a Purpose1948 Oldsmobile Futuramic introduction. In its final year of 1950 the Seventy-Six continued to offer the DeLuxe trim package that was also offered on the station wagon, while the Holiday hardtop coupe was briefly offered, manufacturing only 144 with the standard trim package and 394 with the DeLuxe package and a listed retail price of US$2,108 ($25,640 in 2022 dollars [5] ). This particular model is particularly rare to find as it was the only time Oldsmobile offered a six-cylinder engine with the upscale hardtop feature. [4] The hardtop was built by welding a steel roof onto the convertible body style which simplified assembly line operations. [4]

The Seventy-Six was available in the following body styles:

The Oldsmobile Cutlass was a series of automobiles produced by General Motors' Oldsmobile division between 1961 and 1999. At its introduction, the Cutlass was Oldsmobile's entry-level model; it began as a unibody compact car, but saw its greatest success as a body-on-frame intermediate. The Cutlass was named after Vought F7U Cutlass, as well as the type of sword, which was common during the Age of Sail.

<span class="mw-page-title-main">Oldsmobile 98</span> Flagship car model produced by Oldsmobile from 1940 to 1996

The Oldsmobile 98 is the full-size flagship model of Oldsmobile that was produced from 1940 until 1942, and then from 1946 to 1996. The name – reflecting a "Series 90" fitted with an 8-cylinder engine – first appeared in 1941 and was used again after American consumer automobile production resumed post-World War II. It was, as it would remain, the division's top-of-the-line model, with lesser Oldsmobiles having lower numbers such as the A-body 66 and 68, and the B-body 76 and 78. The Series 60 was retired in 1949, the same year the Oldsmobile 78 was replaced by the 88. The Oldsmobile 76 was retired after 1950. This left the two remaining number-names to carry on into the 1990s as the bread and butter of the full-size Oldsmobile lineup until the Eighty Eight-based Regency replaced the 98 in 1997.

<span class="mw-page-title-main">Oldsmobile 88</span> American full-size car built by Oldsmobile

The Oldsmobile 88 is a full-size car that was sold and produced by Oldsmobile from 1949 until 1999. From 1950 until 1974, the 88 was the division's most profitable line, particularly the entry level models such as the 88 and Dynamic 88. The 88 series was also an image leader for Oldsmobile, particularly in the early years (1949–51), when it was one of the best performing automobiles, thanks to its relatively small size, light weight, and advanced overhead-valve high-compression V8 engine. This engine, originally designed for the larger C-bodied and more luxurious 98 series, also replaced the straight-8 on the smaller B-bodied 78. With the large, high performance V8, the Oldsmobile 88 is considered by some to be the first muscle car, although this title is disputed.

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.

<span class="mw-page-title-main">Pontiac 6</span> Motor vehicle

The Pontiac 6 was a more affordable version of its predecessor Oakland Six that was introduced in 1926, sold through Oakland Dealerships. Pontiac was the first of General Motors companion make program where brands were introduced to fill in pricing gaps that had developed between Cadillac, Buick, Oldsmobile, Oakland and Chevrolet. The original marketing approach began when GM was incorporated in 1908 was to offer a range of vehicles in various body styles based on affordable to extravagant, and the customer base would gradually trade up every few years to the next hierarchy brand. Pontiac was introduced as an affordable Oakland, followed by LaSalle for Cadillac, Marquette for Buick and Viking for Oldsmobile. Pontiac's introduction was a sales success while customers shied away from the more expensive Oakland, and once the Wall Street Crash of 1929 and the Great Depression followed, both Pontiac and Oakland were being considered for cancellation but the decision was made to keep Pontiac as the economy began to recover.
