Looking very similar to the 1927 Series AA Capitol, the wheelbase of the Series AB was increased by four inches to 107 in (2,718 mm). The updated look was one of the first projects from GM's Art & Colour studio. It was the last Chevrolet to use a four-cylinder engine until 1961 and the Chevrolet Chevy II / Nova. Roadsters and touring sedans had the ability to fold the windshield forward on top of the cowl for open air driving.
The Series AB was powered by Chevrolet's old 171 cu in (2,800 cc) four-cylinder engine, but with minor modifications to produce 35 hp (26 kW) at 2,200 rpm. Four-wheel braking was also now provided. Fisher Body provided eight different coachwork choices to include both open and closed body styles. The top choice was listed as the Imperial Landau listed at US$715 ($10,646 in 2019 dollars ). In May of 1925 the Chevrolet Export Boxing plant at Bloomfield, New Jersey was repurposed from a previous owner where Knock-down kits for Chevrolet, Oakland, Oldsmobile, Buick and Cadillac passenger cars, and both Chevrolet and G. M. C. truck parts are crated and shipped by railroad to the docks at Weehawken, New Jersey for overseas GM assembly factories.
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 brands - 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.
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 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 make, 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 hierarchy.
The Chevrolet Superior Series F was launched in 1923, manufactured by Chevrolet for four years 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 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. Starting with 1918, 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 Standard was launched in 1933, initially as the Chevrolet Standard Mercury, by Chevrolet as a lower priced alternative to the 1932 Chevrolet Series BA Confederate that became the Master Eagle in 1933 and Master from 1934. It was advertised as the cheapest six-cylinder enclosed car on the market.
The Chevrolet Series AD Universal or Chevrolet Universal AD is a Chevrolet car which began sales in 1930. Available in a variety of body types including as a 2-door coupe, 4-door sedan and a delivery van. Total production was down due to the Wall Street Crash of 1929 while 864,243 were manufactured and 39,773 came from Oshawa. The 7th million Chevrolet since 1912 was built May 28, 1930 at Flint Assembly
The Chevrolet Series AA Capitol is an American vehicle manufactured by Chevrolet in 1927. Launched in the year Ford changed from the Model T to the Model A, Chevrolet sold 1,001,820 Series AA cars, and under the direction of General Manager William S. Knudsen Chevrolet would overtake Ford’s dominance in the market internationally. The GM introduction of the GM A platform also introduced yearly appearance changes while using a corporate appearance from the newly established Art and Color Section headed up by Harley Earl which meant the Chevrolet Capitol and the Cadillac Series 314 shared a common appearance as both cars, as well as Oakland, Oldsmobile and Buick used Fisher Body, now owned by GM, as the sole provider of coachwork. Individuality between the brands was defined by the manufacturer of the engine, which was brand exclusive, and badging on the radiator. This model documents that the accelerator pedal was introduced as previous generations used a throttle installed in the center of the steering column along with the installation of a gas gauge installed in the dashboard and a centrally installed rear view mirror.
The Chevrolet Series AC International is an American vehicle manufactured by Chevrolet in 1929 to replace the 1928 Series AB National. In all, 1,328,605 Series ACs were manufactured in a range of ten body styles, with 73,918 from Oshawa. The Series AC was the first introduction of the overhead valve Chevrolet straight-6 engine since the 1915 Chevrolet Series C Classic Six, and was advertised as "A Six in the price range of the Four", and was only $10 more than the outgoing four-cylinder Series AB. To simplify production operations, each factory was designated one body style for national consumption. The serial number of origin was relocated to the right body sill underneath the rubber floormat except for the roadster and phaeton, which were inscribed on the right side of seat frame. Prices listed started at US$525 for the roadster or phaeton to US$725 for the Landau Convertible.
The Chevrolet Series AE Independence is an American vehicle manufactured by Chevrolet in 1931 to replace the 1930 Series AD Universal. Calendar year production slipped by about eight percent to 627,104 cars as the Great Depression continued, but as Ford's output plummeted by nearly two-thirds, Chevrolet reclaimed first place in the American car sales table, and the 8th million car was produced August 25, 1931. Yearly appearance changes, technical updates and standard or optional features for 1931 included the introduction of the "quail" hood ornament, a curved tie-bar connecting the headlights, wire- spoked wheels became standard equipment, while optional equipment listed front and rear bumpers, covers for side mounted spare tires, spotlights and guide lamps that would turn with the front tires. William S. Knudsen was joined with M. E. Coyle as General Managers. In May of 1925 the Chevrolet Export Boxing plant at Bloomfield, New Jersey was repurposed from a previous owner where Knock-down kits for Chevrolet, Oakland, Oldsmobile, Buick and Cadillac passenger cars, and both Chevrolet and G. M. C. truck parts are crated and shipped by railroad to the docks at Weehawken, New Jersey for overseas GM assembly factories. Dedicated body style production continued while assignment changed from previous years based on demand.
The Chevrolet Series BA Confederate is an American vehicle manufactured by Chevrolet in 1932 to replace the 1931 Series AE Independence. Production slipped significantly from over 600,000 cars to 323,100 for the model year as the Great Depression continued, but was still sufficient for Chevrolet to retain first place in the American car sales table. Sales were also affected by cross-town rival Ford introducing the Ford V8 coupe and sedan. A new body style called a station wagon was produced in limited quantities by coachbuilder Mifflinburg Body Company of Mifflinburg, Pennsylvania.
The Chevrolet Master Eagle is an American vehicle manufactured by Chevrolet in 1933 to replace the 1932 Series BA Confederate. The Eagle was produced early in the 1933 production year. When it was joined by the cheaper Chevrolet Mercury later in 1933 the Eagle name was changed to Master to provide Chevrolet with a two-car range, and the first time in ten years they manufactured two models on different wheelbases. The Mercury was also known as the Standard series. Starting in 1929, GM introduced the short lived General Motors Companion Make Program where Oakland, Oldsmobile, Buick and Cadillac had "junior" models added to each division, but weren't labeled according to their "senior" brand. The only division that didn't get a "junior" brand was Chevrolet. Two different models were introduced as Chevrolet to determine which one the market liked better, and sold better.
The Chevrolet Master and Master Deluxe are American passenger vehicles manufactured by Chevrolet between 1933 and 1942 to replace the 1933 Master Eagle. It was the more expensive model in the Chevrolet range at this time, with the Standard Mercury providing an affordable product between 1933 and 1937. Starting with this generation, all GM cars shared a corporate appearance as a result of the Art and Color Section headed by Harley Earl. From 1940 a more expensive version based on the Master Deluxe was launched called the Special Deluxe. This was the last Chevrolet that was exported to Japan in knock down kits and assembled at the company's factory in Osaka, Japan before the factory was appropriated by the Imperial Japanese Government. When Toyota decided to develop their own sedan called the Toyota AA, a locally manufactured Master was disassembled and examined to determine how Toyota should engineer their own cars. In May of 1925 the Chevrolet Export Boxing plant at Bloomfield, New Jersey was repurposed from a previous owner where Knock-down kits for Chevrolet, Pontiac, Oldsmobile, Buick and Cadillac passenger cars, and both Chevrolet and G. M. C. truck parts are crated and shipped by railroad to the docks at Weehawken, New Jersey for overseas GM assembly factories.
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 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 built from the 1928 through 1938. 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. 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 F-Series was Oldsmobile's entry-level product using the Oldsmobile straight-6 engine, while the Oldsmobile L-Series, with a Oldsmobile Straight-8 engine, was the top level vehicle. It replaced the Oldsmobile Model 30 introduced in 1923, and was replaced by the Oldsmobile Series 60 and Oldsmobile Series 70 introduced in 1938. It was exported to Japan as a knock down kit and assembled at Osaka Assembly in Osaka, Japan
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 along with an electric lighting system. 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 Pontiac Six was a more affordable version of the 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 begun 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.
Saginaw Metal Casting Operations is an automobile engine foundry plant in Saginaw, Michigan. Opened under GM management in 1919, the factory produces engine blocks and cylinder heads for General Motors vehicles. The factory currently occupies 1.9 million square feet on 490 acres. The location was originally the Marquette Motor Company until acquired by William Durant in 1909 when the car was discontinued in 1911. During World War I, it was used to manufacture mortar shells for the US Ordnance Corps, then was repurposed for engine block casting when operations at Northway Motor and Manufacturing Division ended in 1925. Historically in September 1927 it was known as the Chevrolet Grey Iron Foundry. In the past when it was called GM-Saginaw Product Company (SPC) a cloverleaf casting symbol mark was cast onto the iron component.
