The Buick LeSabre was a full-size car made by General Motors from 1959 to 2005. Prior to 1959, this position had been retained by the full-size Buick Special model (1936–58). The name originated with the 1951 GM Le Sabre show car designed by Harley Earl; that car is often mistakenly attributed to the Buick division but in fact it was presented as a GM vehicle without reference to a specific GM division.
Buick closely related their 1956-1957 models to the GM LeSabre by replicating the top section of the rear wing into their design. The word LeSabre is French for sabre.
