LaSalle was an American brand of luxury automobiles manufactured and marketed, as a separate brand, by General Motors' Cadillac division from 1927 through 1940. Alfred P. Sloan, GM's Chairman of the Board, developed the concept for four new GM marques - LaSalle, Marquette, Viking and Pontiac - paired with already established brands to fill price gaps he perceived in the General Motors product portfolio. Sloan created LaSalle as a companion marque for Cadillac. LaSalle automobiles were manufactured by Cadillac, but were priced lower than Cadillac-branded automobiles, were shorter, and were marketed as the second-most prestigious marque in the General Motors portfolio. LaSalles were titled as LaSalles, and not as Cadillacs. Like Cadillac — named after Antoine de la Mothe Cadillac — the LaSalle brand name was based on that of another French explorer, René-Robert Cavelier, Sieur de La Salle.
The Oldsmobile Series 70 is a full-size midrange automobile produced by Oldsmobile between the 1939 and 1950 model years. 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" Chevrolets and Pontiacs, while Oldsmobiles using the "B" platform were "budget priced" Buicks and Cadillacs.
Viking was a brand of automobiles manufactured by General Motors as a supplement to Oldsmobile division for model years 1929 to 1931 and used the GM B platform. It was shared with the Oakland Model 301 for 1930 and 1931.
The Oakland Motor Car Company of Pontiac, Michigan, was an American automobile manufacturer and division of General Motors. Purchased by General Motors in 1909, the company continued to produce modestly priced automobiles until 1931 when the brand was dropped in favor of the division's Pontiac make.
In the late 1920s, American automotive company General Motors (GM) launched four companion makes to supplement its existing lineup of five-passenger car brands, or makes. The companion makes were LaSalle, introduced for the 1927 model year to supplement Cadillac; Marquette, introduced in 1929 for 1930 to supplement Buick; Pontiac, introduced for 1926 to supplement Oakland; and Viking, introduced for 1929 to supplement Oldsmobile. GM's fifth existing brand, Chevrolet, did not receive a companion make. With the exception of Viking, each of the companion makes were slotted below their "parent make" in GM's pricing hierarchy.
Marquette was an American automobile manufacturer established by General Motors in 1909 after the purchase of the Rainier Motor Car Company. The Marquette Company did not last long and in 1912 GM announced the company would be closed.
The Buick Standard Six Series 20 was manufactured by Buick at what would later become known as the Buick City factory on Hamilton Ave. in Flint, Michigan, and was the junior model to the Buick Master Six between 1925 through 1929, and shared the GM A platform with Oldsmobile, Oakland and Chevrolet. The Standard Six evolved from the earlier Buick Six when the Buick 4-cylinder was cancelled. The Standard Six was the most popular Buick sold while being more upscale to the Oldsmobile Six. It was the senior brand to Marquette under the General Motors Companion Make Program until Marquette was cancelled one year later. It replaced the earlier Buick Six that was introduced in 1916, and was replaced with the Buick Series 50. Coachwork continued to be offered by Fisher Body who was the primary supplier of all GM products at this time, and Duco automotive lacquer paint, introduced by DuPont was the first quick drying multi-color line of nitrocellulose lacquers made especially for the automotive industry.
The Chevrolet Superior Series F was manufactured by Chevrolet from 1923 to 1926, with a different series per year. The 1923 model was known as the Series B, the 1924 model was the Series F, for 1925 it was known as the Series K and the 1926 Superior was known as the Series V. It was replaced in 1927 by the Series AA Capitol. It was the first Chevrolet that didn't have a larger companion model and was the only car sold by Chevrolet in several body style configurations all supplied by Fisher Body. Each year new mechanical changes, appearance updates or optional features that became standard in subsequent years became expected of all GM products including Chevrolet. Body styles were separated into open and closed which meant closed included retractable glass in the doors and glass surrounding rear seat passengers. Standard items included tools, a jack for tire removal, speedometer, outside lockable door handles, ammeter, oil pressure gauge, dashboard light, choke pull knob, electric horn, ignition theft lock, and a two piece vertical ventilating windshield that allowed fresh air to enter the passenger compartment. Wheels were 30" and came standard with hickory wood spokes or optional pressed steel discs. For 1925, bumpers were offered optionally along with outside side view mirrors, heater for passenger compartment and a clock.
The Buick Master Six, also denoted Series 40 and Series 50 based on the wheelbase used, was an automobile built by Buick from 1925 to 1928 and shared the GM B platform with the Oldsmobile Model 30. Previously, the company manufactured the Buick Six that used the overhead valve six-cylinder 242 cu in (4.0 L) engine in their high-end cars, and the Buick Four for smaller, less-expensive cars. After 1924, they dropped the four-cylinder engine and designed a small six, which they called the Buick Standard Six, to replace that end of the market. They coined the name "Master Six" for the high-end cars, now powered by the 255 cu in (4.2 L) engine released the year before. The yearly changes were a result of a new business philosophy called planned obsolescence.
The Chevrolet Series AB National is an American vehicle manufactured by Chevrolet in 1928 to replace the 1927 Series AA Capitol. Documented production numbers show that 1,193,212 Series ABs were manufactured in a variety of body styles with 69,217 originating from the Oshawa factory alone. Chevrolet instituted serial number recorded on the front seat heel board on either the left or right side, using the listed numbers to designate the point of origin of the vehicle identified.
The Buick 4 was a series of passenger cars produced by the Buick Division of GM from 1909 through 1918, and was available as a touring car, phaeton or roadster. It was available with the Buick Model B as a larger alternative offering a larger engine and better durability. It became the junior sedan in 1914 when the Buick Six was introduced.
The Oldsmobile Model 30, which continued to be known as the Oldsmobile Six, was built from the 1923 through 1927. Each year it was built, it was given the suffix 30-A, 30-B, 30-C, 30-D and 30-E for the last year of production, all having been manufactured in Lansing, Michigan. General Motors used the GM A platform, shared with the Buick Standard Six and the Oakland Six, and the yearly changes were the result of a new business philosophy called planned obsolescence. The Model 30 was Oldsmobile mid-level product and introduced the flathead Oldsmobile straight-6 engine, while the Oldsmobile Model 43 with a four-cylinder engine remained the entry level product. When the top level Oldsmobile Light Eight, with the flathead Oldsmobile V8 engine was cancelled in 1923, the Oldsmobile Six became the top level vehicle. It replaced the Oldsmobile Model 37 introduced in 1917, and was replaced by the Oldsmobile F-Series introduced in 1928. In 5 years, 236,474 cars were built. The growing popularity of GM's brands, like Oldsmobile, contributed to becoming the largest automobile manufacturer when sales overtook the Ford Motor Company during this time period. Coachwork for the various bodystyles were supplied by Fisher Body of Detroit, MI, and starting with the 1923 model year, all GM products adopted a shared appearance, with brand specific unique appearance features. The retail price had dropped considerably from previous years due to the popularity and affordability of the Ford Model T, with the top level sedan at US$1,095.
The Model 42 was an entry-level four seat passenger car produced by GM's Oldsmobile Division in 1914. It was offered as a replacement to the Oldsmobile Curved Dash runabout when it was discontinued in 1908, and was the junior platform to the Oldsmobile Six introduced in 1913. GM had acquired Elmore Manufacturing Company, Oldsmobile and Oakland Motor Car Company in 1908 and Cartercar and Rainier Motor Car Company in 1909 as their entry-level models, and Oldsmobile products were being repositioned in their new hierarchy as GM began to consolidate operations after William Durant had left.
The Oldsmobile Six, also known as the Model 53, 54 and 55 (1913-1915) then a brief cancellation until it reappeared as the Model 37, 37A and 37B (1917-1921) was a top level sedan along with the Oldsmobile Series 40 junior vehicle produced by GM's Oldsmobile Division and was manufactured at Lansing Car Assembly in Lansing, Michigan. It replaced the Series 28 also known as the "Oldsmobile Autocrat" and was replaced by the Oldsmobile Model 30 in 1927, and shared wheelbases with the Buick Six. It continued to use the T-head engine for two years. The various bodystyles were supplied by Fisher Body of Detroit, MI. It competed with the Chevrolet Series C Classic Six as Chevrolet was an independent company before becoming a division in 1917. Oldsmobile also shared technology with GMC for commercial and industrial products.
The Oldsmobile F-Series was a pre-WWII passenger car built from the 1928 through 1938 model years. The first generation continued the tradition of adding a series number for each model year; F-28, F-29, F-30 and F-31. The second generation, signified by a completely new bodystyle appearance was built from 1932 through 1938, all having been manufactured in Lansing, Michigan. 1926 saw the introduction of GM's most recognized business model, the use of common platforms shared amongst the brands, and Oldsmobile and Buick shared the GM B platform. The F-Series was shared with the Buick Master Six and was also known as the Oldsmobile Six which was introduced as a name earlier in 1913.
The Oldsmobile Light Eight was an automobile produced by the Oldsmobile Division of General Motors in roadster, two-door coupe, four-door sedan from between 1916 and 1923. It was powered by a sidevalve V8 engine, the maker's first, and shared with the 1916 Oakland Model 50.
The Buick Six was a top level automobile produced by GM's Buick Division which was first introduced in 1914, and was the senior vehicle to the Buick Series B Four. It was an all new platform which was shared with the Oldsmobile Six and was the first Buick to implement a steering wheel on the left side, and electric starter provided by Delco Remy along with an electric lighting system and electric Klaxon horn. The gearshift and emergency brake were relocated to a central position inside the vehicle, an approach used on all GM products for 1914. It continued to use the patented overhead valve engine implemented by Walter Lorenzo Marr while the cylinder head was not removable until later developments. The engine displacement was 331 cu in (5.4 L) and the wheelbase was 130 in (3,302 mm). The first year Buick Six was only offered as a touring sedan for US$1,985.
The Oakland Model A was the first four-cylinder engine offered by the Oakland Motor Company in 1907, which became a division of General Motors in 1909. The Model A was developed and manufactured from former Oakland Motor Company sources while the engine was provided by Northway Motor and Manufacturing Division of GM of Detroit. The Model A was available in several body styles and prices ranged from US$1,300 to US$2,150. Once Oakland became a division of GM, Oldsmobile and Buick shared bodywork and chassis of their four-cylinder models with Oakland. Manufacture of the Oakland was completed in Pontiac, Michigan. Oakland (Pontiac) wouldn't use another 4-cylinder engine until 1961 with the Pontiac Trophy 4 engine.
The Oakland Six was the first six-cylinder engine offered by the Oakland Motor Company in 1913 which became a division of General Motors in 1909. The Oakland Six was offered in many different model names that changed every year, along with several body styles and engine displacements until 1929, when the V8 was reintroduced, then in 1931 Oakland was renamed Pontiac. When Oakland became a division of GM and introduced the Oakland Four, Oldsmobile and Buick shared bodywork and chassis of their six-cylinder models with Oakland. When Chevrolet became part of GM in 1917, Oakland chassis and bodywork were shared with Chevrolet. Manufacture of the Oakland was completed in Pontiac, Michigan.
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.
