The Jetta TDI Cup Series did so well this year that Volkswagen is expanding the series from eight to ten races next year. And now non-racers may have a chance to live the diesel racing dream, and if they do, it will look very similar to the Jetta TDI Cup Edition Street Concept unveiled at the SEMA Show in Las Vegas today. The diesel-powered sport sedan gets upgraded sway bars and brakes from the Euro-spec Jetta GLI and a 'European sport-tuned suspension', along with some cosmetic enhancements like a three-spoke steering wheel, sill plates, and Interlagos sport seats. This is one of those, 'If we get the right response we'll might make it' deals, but VW is so open to producing this sport version of the Jetta TDI that it even has a price point already established: under $30,000. So have look at the high-res gallery of images below and let VW know what you think. We say build it.
