Sloan, who had replaced du Pont as GM president in 1923, decided to create various "companion makes" to fill the variety of gaps that had developed in the original pricing hierarchy. These companion makes, introduced within GM's existing divisions as opposed to being treated as independent marques, were intended to increase sales of the parent division while costing less to produce.
Oakland introduced Pontiac at the 1926 New York Auto Show as a low-priced model for the 1926 model year, followed by a sales meeting at the Commodore Hotel. The name dated to 1893 as a coachbuilding business that had been the predecessor of Oakland's automotive ventures, and was an homage to both its factory in Pontiac, Michigan, and the Native American chief of the same name. Touted as "the Chief of the Sixes" for its six-cylinder inline engine, it was designed from scratch by Ben H. Anibal, who had previously been Cadillac's chief engineer, to the order of Oakland's general manager Al R. Glancy. By the 1929 model year, its flathead engine was able to make 60 brake horsepower (bhp) (45 kW). The chassis had a wheelbase of 110 in, and the car was available in such body styles as a roadster, phaeton, coupe, convertible, two- or four-door sedan, or landaulet.
In early 1926, Lawrence P. Fisher, the general manager of the Cadillac division, visited a Los Angeles Cadillac dealership run by Don Lee that also made custom cars for Hollywood actors and producers. The director of the custom car operation, Harley Earl, would turn boxy factory automobiles into sleek low-riding roadsters, something that thrilled Fisher. Fisher hired Earl in spring 1926 to design a sleek low-priced vehicle to be introduced by Cadillac in 1927 known as the LaSalle. Sloan was sufficiently impressed by the result that he made Earl head of a special design division of GM, established in June 1927. The LaSalle itself was introduced in March 1927 for the 1927 model year. By the 1929 model year it had a V8 engine with a newly-introduced synchromesh transmission. It came with a wheelbase of either 128 in or 134 in; the former was available as a roadster and various forms of phaeton, while the latter was available in various forms of convertible, various forms of coupe, or various forms of sedan.
Oldsmobile introduced the Viking in March 1929 for the 1929 model year. The Viking served as the upscale counterpart of Oldsmobile's F-29 model, which had a 62 bhp six-cylinder inline engine. The Viking, by contrast, had a monoblock 81 hp V8 engine. Its logo, a stylized "V", stood for both "Viking" and "V8". It resembled the LaSalle in appearance, had a 125 in wheelbase, and was available as a convertible, a close-coupled sedan, or standard sedan. It was initially priced at $1,595, but by the end of 1929 had become worth $1,695. During his 1930 visit to the United States to attempt a land speed record in the Silver Bullet, British racer Kaye Don used a Viking for casual driving and to test the terrain of his record attempt.[6] A retrospective noted it as a "fine car" that "doubtless...would have survived" but for the Great Depression.
After Buick sales had declined in the previous several years and following the successes of Pontiac and LaSalle, Buick introduced Marquette to showrooms on June 1, 1929, for the 1930 model year.[7][8] Unlike Buick, which was noted for its overhead valve engine, the Marquette had a flathead six-cylinder engine based on Oldsmobile's.[8] A prominent selling point was its fine engineering and craftsmanship; its engineers remarked that one could drive it at 60 mph without damaging the engine, and one was driven from Death Valley to Pikes Peak without any issues.[7] Other standard features included an air cleaner and a large muffler.[7] Having a 114 in wheelbase with its engine making 67 hp, it was offered as a roadster, phaeton, one of two styles of coupe, or one of two styles of sedan. It possessed distinctive styling, with a portly shape that led to its sobriquet of "the pregnant Buick" and a herringbone radiator, to distinguish it from other GM makes.[8]
