" Video: 2011 Kohler International Challenge &amp;amp;amp; R&amp;amp;amp;T Concours d&amp;#039; Elegance &amp;amp;gt;&amp;amp;gt;   In the mid-1970s, there were several attempts by U.S.-based teams to compete in Formula 1...Vel&amp;#039;s Parnelli Jones, Shadow and Roger Penske. Always ready to take on any racing series with success, the Penske effort started in 1975 with the PC1 and continued through the 1976 season. The team designed its own chassis, which used the Cosworth DFV V-8 employed by most teams.   Come 1976, the team had developed the PC4 chassis and with it scored the team&amp;#039;s only Grand Prix victory, the Austrian Grand Prix. In a strange twist, just the year before, Penske&amp;#039;s long-time leading driver, Mark Donohue, had died as the result of an accident at the same track.   The Penske PC4 seen here was found in Germany and was determined to be the car John Watson drove to that single win for the team. Doug Mockett saved the PC4 from a life of dust, had it restored with input from Penske and now races it in the Historic Grand Prix events.   "^^<http://www.w3.org/2001/XMLSchema#string>
