The Daewoo Tosca is a mid-size car designed by Daewoo in South Korea and marketed by Chevrolet as the Chevrolet Epica and Chevrolet Tosca, while Holden marketed it as the Holden Epica. Codenamed V250, it replaces the Daewoo Magnus and its derivatives. The Chevrolet Epica was officially launched in Europe at the 2006 Geneva Motor Show. The Tosca is noteworthy in that it is available with transversely-mounted straight-six engines. Contrary to the preceding models, which were styled by Giugiaro, the V250 was designed entirely in-house.

Daewoo Motors was a South Korean automotive company established in 1937 as "National Motors". The company changed its name several times until 1982 when it became "Daewoo Motors" following its acquisition by the Daewoo Group. After running into financial difficulties, it sold most of its assets in 2002 to General Motors at $1.2 billion, becoming a subsidiary of the American company. In 2011, the name "Daewoo" was definitively removed with the company being renamed GM Korea and the Daewoo brand replaced by the Chevrolet marque.
