Chevrolet colloquially referred to as Chevy, is an American automobile division of the manufacturer General Motors (GM).

Louis Chevrolet (1878–1941), Arthur Chevrolet (1884–1946) and ousted General Motors founder William C. Durant (1861–1947) started the company on November 3, 1911 as the Chevrolet Motor Car Company. Durant used the Chevrolet Motor Car Company to acquire a controlling stake in General Motors with a reverse merger occurring on May 2, 1918, and propelled himself back to the GM presidency. After Durant's second ousting in 1919, Alfred Sloan, with his maxim "a car for every purse and purpose", picked the Chevrolet brand to become the volume leader in the General Motors family, selling mainstream vehicles to compete with Henry Ford's Model T in 1919 and overtaking Ford as the best-selling car in the United States by 1929 with the Chevrolet International.[4]

On November 8, 1911, the Chevrolet Motor Car Company was incorporated. It was founded by Swiss race car driver and automotive engineer Louis Chevrolet with his brother Arthur Chevrolet, William C. Durant and investment partners William Little (maker of the Little automobile), former Buick owner James H. Whiting, Edwin R. Campbell (son-in-law of Durant) and in 1912 R. S. McLaughlin CEO of General Motors in Canada. Former Buick officers were also employed, including Curtis R. Hatheway as secretary.

Durant was dismissed from his senior management position at General Motors in 1910, a company that he had founded in 1908. In 1904 he had taken over the Flint Wagon Works and Buick Motor Company of Flint, Michigan. He also incorporated the Mason and Little companies. As head of Buick, Durant had hired Louis Chevrolet to drive Buicks in promotional races. Durant planned to use Chevrolet's reputation as a racer as the foundation for his new automobile company. The first factory location was in Flint, Michigan at the corner of Wilcox and Kearsley Street, now known as "Chevy Commons" at coordinates 43.00863°N 83.70991°W, along the Flint River, across the street from Kettering University.

One of the technical advancements Chevrolet benefited from was the implementation of an overhead valve engine from the very beginning, as the company was developed by the former owner of Buick, which had patented the overhead valve and cross-flow cylinder design as being more efficient than the conventional use of the flathead engine.

Actual design work for the first Chevy, the costly Series C Classic Six, was drawn up by Etienne Planche, following instructions from Louis. The first C prototype was ready months before Chevrolet was actually incorporated. However, the first actual production was not until the 1913 model. So in essence there were no 1911 or 1912 production models, only one pre-production model was made and fine tuned throughout the early part of 1912. Then in the fall of that year the new 1913 model was introduced at the New York auto show.

Chevrolet first used the "bowtie emblem" logo in 1914 on the H series models (Royal Mail and Baby Grand) and The L Series Model (Light Six). It may have been designed from wallpaper Durant once saw in a French hotel room. More recent research by historian Ken Kaufmann presents a case that the logo is based on a logo of the "Coalettes" coal company. An example of this logo as it appeared in an advertisement for Coalettes appeared in the Atlanta Constitution on November 12, 1911. Others claim that the design was a stylized Swiss cross, in tribute to Chevrolet's home country. Over time, Chevrolet used several different iterations of the bowtie logo at the same time, often using blue for passenger cars, gold for trucks, and an outline (often in red) for cars that had performance packages. Chevrolet eventually unified all vehicle models with the gold bowtie in 2004, for both brand cohesion as well as to differentiate itself from Ford (with its blue oval logo) and Dodge (who has often used red for its imaging), its two primary domestic rivals.

Louis Chevrolet had differences with Durant over design and in 1914 sold Durant his share in the company. By 1916, Chevrolet was profitable enough with successful sales of the cheaper Series 490 to allow Durant to repurchase a controlling interest in General Motors. After the deal was completed in 1918, Durant became president of General Motors, and Chevrolet was merged into GM as a separate division. In 1919, Chevrolet's factories were located at Flint, Michigan; branch assembly locations were sited in Tarrytown, N.Y., Norwood, Ohio, St. Louis, Missouri, Oakland, California, Ft. Worth, Texas, and Oshawa, Ontario General Motors of Canada Limited. McLaughlin's were given GM Corporation stock for the proprietorship of their Company article September 23, 1933 Financial Post page 9. In the 1918 model year, Chevrolet introduced the Series D, a V8-powered model in four-passenger roadster and five-passenger tourer models. Sales were poor and it was dropped in 1919.

Beginning also in 1919, GMC commercial grade trucks were rebranded as Chevrolet, and using the same chassis of Chevrolet passenger cars and building light-duty trucks, sharing an almost identical appearance with GMC products.

Until 1921, Chevrolet Corporate headquarters were located at 57th and Broadway in New York City until April when the office was relocated to the General Motors Building at Cadillac Place in Detroit. In January 1921 a General Motors management survey recommended that the Chevrolet Division be cancelled, but Alfred P. Sloan Jr. recommended that the division be saved and William S. Knudsen, a former Ford employee who oversaw production of the Model T, was made Vice President of Operations and performance improved In May 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.

Chevrolet continued into the 1920s, 1930s, and 1940s competing with Ford, and after the Chrysler Corporation formed Plymouth in 1928, Plymouth, Ford, and Chevrolet were known as the "Low-priced three". In 1929 they introduced the famous "Stovebolt" overhead-valve inline six-cylinder engine, giving Chevrolet a marketing edge over Ford, which was still offering a lone flathead four ("A Six at the price of a Four"). In 1933 Chevrolet launched the Standard Six, which was advertised in the United States as the cheapest six-cylinder car on sale. During the Great Depression the Chevrolet Master introduced a streamlined appearance, showing Art Deco influences and before and after the World War II era, the Chevrolet Deluxe and Chevrolet Fleetline found many buyers.

Chevrolet had a great influence on the American automobile market during the 1950s and 1960s. In 1953 it produced the Corvette, a two-seater sports car with a fiberglass body. In 1957 Chevy introduced its first fuel injected engine, the Rochester Ramjet option on Corvette and Chevrolet Bel Air passenger cars, priced at $484 ($5,251 today). In 1960 Chevrolet joined the newly popular "compact car" market by introducing the Corvair, with a rear-mounted air-cooled engine. In 1963 one out of every ten cars sold in the United States was a Chevrolet.
