Another issue of contention is whether the merger delivered promised synergies and successfully integrated the two businesses. Martin H. Wiggers' concept of a platform strategy like the VW Group, was implemented only for a few models, so the synergy effects in development and production were too low. As late as 2002, DaimlerChrysler appeared to run two independent product lines. Later that year, the company launched products that appeared to integrate elements from both sides of the company, including the Chrysler Crossfire, which was based on the Mercedes SLK platform and utilized Mercedes's 3.2 L V6, and the Dodge Sprinter/Freightliner Sprinter, a re-badged Mercedes-Benz Sprinter van.
