The Daewoo Tosca is a mid-size car built by GM Daewoo in South Korea and marketed worldwide by General Motors mainly as Chevrolet Epica, but also as the Holden Epica. It replaces the Daewoo Magnus and its derivatives. The Chevrolet Epica was officially launched in Europe at the 2006 Geneva Motor Show. The internal code for this model is V250, and is unique in that it is powered transversely-mounted straight six engines. Contrary to the preceding models (V100 Leganza and V200 Magnus), which were styled by Giugiaro, the V250 was designed entirely in-house. The car was also introduced to Australia in April 2007, under the name Holden Epica, replacing the Holden Vectra.
