Buick produced its Series 50 with 5,431cc six cylinder engine from 1930, but there was also an 8-cylinder 3,617cc and later 3,776cc. A new model was introduced in 1933 but production ended in 1935. In 1940 the Buick Super was launched built on the larger GM C-body, and essentially became a short bonneted car with a smaller Buick 4.1-litre Fireball 8-cylinder engine. New bodies were given in 1942, including the fastback Sedanet body, and production restarted after WW2 in 1946 until 1949. A new body came in 1949, and again this was a GM C-body but a shorter version shared with the Roadmaster. The engine was enlarged to 4.3-litres for 1950, and the new 5.3-litre V8 was given in 1953. A new GM C-body appeared in 1954, again powered by the 5.3-litre Nailhead V8. Another new GM C-body was given to the Super in 1957, and the Nailhead V8 was enlarged to 6.0-litres, and the 'Super' name was dropped in 1958.
