Question: Louis, Arthur and Gaston Chevrolet's business, the Frontenac Motor Corporation, made racing parts for which car?
Context: The 1920 AAA Championship Car season consisted of 5 races, beginning in Beverly Hills, California on February 28 and concluding in Beverly Hills on November 25.  The AAA National Champion and Indianapolis 500 champion was Gaston Chevrolet.  The 1920 season has been a source of confusion and misinformation for historians since 1926. The Ford Model T (colloquially known as the Tin Lizzie, Leaping Lena, or flivver) is an automobile produced by Ford Motor Company from October 1, 1908, to May 26, 1927.  It is generally regarded as the first affordable automobile, the car that opened travel to the common middle-class American; some of this was because of Ford's efficient fabrication, including assembly line production instead of individual hand crafting. The Anahuac was a short-lived United States automobile styled after a contemporary Polish car and manufactured in 1922 in Indianapolis by the Frontenac Motor Corporation Intended for the export market (it was to have been marketed in Mexico by a Mexican concern), the car had a wheelbase of 115 in ; only four were ever completed. British Motor Corporation (Australia) was a motor manufacturing company formed in Australia in 1954 by the merger of the Austin Motor Company (Australia) and Nuffield (Australia) Pty Ltd.  This followed the merger in 1952 of the Austin Motor Company and the Nuffield Group in the United Kingdom to form the British Motor Corporation.  Following further corporate changes in the UK in the late 1960s, BMC Australia was absorbed into the newly established British Leyland Motor Corporation of Australia, the name of which became Leyland Motor Corporation of Australia in 1972, and then JRA Limited in March 1983. Gaston Chevrolet (4 October 1892 – 25 November 1920) was a French-born American racecar champion driver and automobile manufacturer. Tacoma Speedway (sometimes called Pacific Speedway or Tacoma-Pacific Speedway) was a 2 mi (approximate) wooden board track for automobile racing that operated from 1914 to 1922 near Tacoma, Washington.  In its time, the track was renowned nationwide and was considered by some to be second only to the Indianapolis Motor Speedway.  Notable competitors such as Barney Oldfield, Eddie Rickenbacker, Ralph DePalma, and both Louis and Gaston Chevrolet, were drawn to race for purses of up to $25,000 (approximately $573,000 in 2012 dollars).  Before long, the track acquired a reputation for being dangerous.  After an arson fire destroyed the wooden grandstands in 1920, the facility was rebuilt but failed financially and racing ended two years later.  The site later became an airport and then a naval supply depot during World War II, and today is occupied by the campus of Clover Park Technical College and neighboring commercial sites in Lakewood, Washington. Louis-Joseph "Louis" Chevrolet (December 25, 1878 – June 6, 1941) was a Swiss-American race car driver, co-founder of the Chevrolet Motor Car Company in 1911, and a founder in 1916 of the Frontenac Motor Corporation, which made racing parts for Ford's Model T.

Chevrolet ( ), colloquially referred to as Chevy and formally the Chevrolet Division of General Motors Company, is an American automobile division of the American manufacturer General Motors (GM).  Louis Chevrolet and ousted General Motors founder William C. Durant 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," would pick 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. Frontenac Motor Corporation was the joint venture of brothers Louis, Gaston, and Arthur Chevrolet.  Named for Louis de Buade de Frontenac, the company's main business was preparing racing parts for Model Ts.
