Chevrolet offers over 20 vehicles and many different enhanced versions in its home market. The brand's vehicles range from subcompact cars to medium duty commercial trucks. Its number one sellers in the United States include the Silverado pickup, which is currently the 2nd best-selling vehicle in the United States behind the Ford F-Series and the Impala, which is the number one selling car with a domestic nameplate in the United States.
North American history
Chevrolet was co-founded by Louis Chevrolet and William C. Durant. Louis Chevrolet was a race-car driver, and William Durant, founder of General Motors, had been forced out of GM in 1910; he wanted to use Chevrolet's designs to rebuild his own reputation as a force in the automobile industry. As head of Buick Motor Company, prior to founding GM, Durant had hired Chevrolet to drive Buicks in promotional races.
Chevrolet first used its "bowtie" logo in 1913. This logo is said to have been designed from wallpaper Durant once saw in a French hotel. Another theory of the design of the mark is that it is a stylized version of the shape of Switzerland, Louis Chevrolet's birthplace. It is not, as sometimes claimed, a "Swiss cross": the geometric shape on the Swiss flag is a Greek cross, and does not resemble the Chevrolet logo.
In 1915, Durant made a trip to Toronto, Ontario to determine the possibility of setting up production facilities in Canada. After meeting with "Colonel Sam" McLaughlin, whose McLaughlin Motor Car Company manufactured the McLaughlin-Buick, it was agreed the Chevrolet Motor Car Company of Canada, operated by McLaughlin, would be created to build Chevrolet cars in Canada. Three years later, the two Canadian operations (Chevrolet was by then a part of GM in the United States) were purchased by GM to become General Motors of Canada Ltd.
By 1916, Chevrolet was profitable enough to allow Durant to buy a majority of shares in GM. After the deal was completed in 1917, Durant was president of General Motors, and Chevrolet was merged into GM, becoming a separate division. In the 1918 model year, Chevrolet introduced the Model D, a V8-powered model in 4-passenger roadster and 5-passenger tourer models. These cars had 288in3 engines with Zenith carburetors and 3 speed transmissions.
Famous Chevy models include the large and luxurious Impala (1958) and the innovative air-cooled rear-engined Corvair. Chevrolet had a great influence on the American automobile market during the 1950s and 1960s. In 1963, one out of every ten cars sold in the United States was a Chevrolet.
The basic Chevrolet small-block V-8 design has remained in continuous production since its debut in 1955, longer than any other mass-produced engine design in the world auto industry, though current versions share few if any parts interchangeable directly with the original. Descendants of the basic small-block OHV V-8 design platform in production today have been much modified with advances such as aluminum block and heads, electronic engine management, and sequential port fuel injection, to name just a few improvements over the 54-model-year design life of the engine concept to date. The small block Chevrolet V-8 is used in current production model (2008) Impala sedans, a variety of light and medium duty Chevrolet trucks, and the current generation Corvette sports car. Depending on the vehicle type in which they're installed, they are built in diaplacements from 5.3 to 7.0 litres with outputs ranging from 180 to over as installed at the factory. It will also be used as a performance option in the forthcoming (2009 model year) revival of the Chevrolet Camaro. The engine design has also been used over the years in GM products built and sold under the Pontiac. Oldsmobile, Buick, Opel (Germany) and Holden (Australia) nameplates. Recently, 6-litre, versions of the small-block V-8 designed initially for the C-5 and C-6 Corvettes have been installed in factory-built high performance versions of the Cadillac CTS sedan known as the CTS-V.
