Volkswagen of America has announced sales numbers for June 2009. While 19,027 units, representing an 18% decrease over June 2008, is puny in the large scheme of things, it should be noted that Volkswagen moved 5,072 diesel models, representing an impressive 26% of total sales.

Clean diesel TDI’s accounted for 29% of VW Touareg sales alone. Volkswagen of America claims that U.S. consumers are starting to realize the many benefits of their clean diesels that attain more than 30% better fuel economy while emitting 25% less greenhouse gas emissions without sacrificing driving dynamics.

Volkswagen also announced today that they have been named a corporate leader in Strategic Visions Total Quality Index (TQI), although calling VW a leader in long-term quality might be pushing it.
