During our time at the 2013 Detroit Auto Show, we had the chance to speak with Volkswagen’s Marc Trahan. Trahan holds an interesting position at Volkswagen. He is the Vice President of Technical Service and Quality for Volkswagen of America. What that position entails is making sure the quality of Volkswagen vehicles are the best they can be. We ask Trahan about his work, what is his favorite powertrain is, and much more.
