The test drivers, who are divided into two teams, put the new models like the T-Cross and the Passat, which is undergoing a major upgrade, through their paces. In a few weeks, they’ll go into series production. This is because the Q acceptance run takes place at an important stage in the product development process (PDP): the transition from pre-production to series production. In addition, once a year the quality testers turn their attention to the cars that are already in series production and sold to customers: for example the Tiguan, the Polo, the Golf sports van “Join”2, the e-Golf3, the Touran and the Arteon R-Line4. Now that these models have come off the production line, do they meet the high quality standards that apply to the Volkswagen brand?
