At the beginning of the 21st century, Freightliner was part of DaimlerChrysler, following the 1998 merger of its parent company with Chrysler; several changes in 2000 were made by the merged company that affected Freightliner. Canadian-based Western Star Trucks, a premium truck manufacturer was acquired in its entirety, giving Freightliner a third truck brand (along with assembly plants in Kelowna, British Columbia, and Ladson, South Carolina). Originally an entity of General Motors, DaimlerChrysler acquired Detroit Diesel, integrating its operations within Freightliner.
