At the Automotive News Europe Congress in Turin, Italy VW director of powertrain research projected that over the next ten years diesel would account for 30 percent of the company's U.S. sales. This projection is actually not much of a stretch for VW. Historically when VW has offered diesels in the US, they have accounted for 15 percent of sales. The Jetta is VW's top selling nameplate in the U.S. and the TDI is projected to account for about 40 percent of those sales. As more diesels are added in the coming years, doubling the market share to 30 percent seems entirely plausible.
