The Daewoo Magnus is a mid-size sedan developed and manufactured by Daewoo Motors until its purchase by General Motors, and now built for GM Daewoo Auto & Technology (GMDAT) by Daewoo Incheon Motor Company at its Bupyeong facility in South Korea. GM Daewoo and other GM divisions, as well as GMDAT stake holder Suzuki, have been marketing this car under different badges in various countries. The car is also known under its internal Daewoo designation of V200. The Project Manager was Dr. W.J Lee.

The V200 is a further development of the Daewoo Leganza (model V100), based on a stretched platform of that model. Launched in 2000, it was sold alongside the Leganza in Korea until the end of V100's production in 2002, when it also superseded it in export markets. The V200 itself has been given an extensive facelift for 2006, which resulted in the model known as V250, or Daewoo Tosca in Korea. The V250 will completely supersede all versions of the V200 during 2006.
