This week we continue to probe the shortcomings of American cars relative to their European counterparts. Yesterday, we asked what American cars should be rally-fied and got some interesting answers (our favorite was the idea of rallying a Panoz Esperante). Today is all about diesels. They have them. We want them. Though you can get your odd diesel Benz or Jetta in the USA, nearly every major company selling cars in this market sells a diesel version of that same car in Europe or Japan.
