This is the Passat Performance Concept. It looks to us like VW is using the terms "performance" and "concept" very loosely here.
World Car Fans reports that Volkswagen is planning on bringing over a new four cylinder engine to the US to replace their aging five cylinder. Before they do that, they're teasing us with this thing. In spite of having 250 horsepower, it is by far the least exciting concept car we've seen in a long time.
Volkswagen even makes a production version of the Passat, the R-Line, that looks more interesting that this concept car. Naturally, that car isn't bound for the US. Beigekrieg is in full effect, it appears.
