 While the PQ46 chassis is based upon the PQ35 platform, there are several differences between the more entry level PQ35 and the mid range PQ46.The majority of the parts used in its construction are simply the same as those used on the Volkswagen B6 Passat and CC models of the same chassis.The import version of Tiguan appeared on the Chinese market in 2009, with a locally built version (aka Shanghai-Volkswagen Tiguan) debuting at 2009 Guangzhou Motor Show.
