When Audi brought the E-Tron Detroit Showcar at this year's Detroit Auto Show everyone believed it previewed the next R4 sports car. Unfortunately, it seems the company hasn't yet decided about the R4 and whether ornot they will move forward with the design.

An insider told AutoCar: "The reaction to the e-tron concept has been overwhelming. We’re weighing up all of the options and possibilities. There’s no real time pressure because we’re not replacing an existing model, but establishing a new one." Apparently, the final decision will be made by the parent company, Volkswagen->ke94.

The R4 was supposed to share the platform with the production version of the BlueSport concept, which was unveiled at the 2009 Detroit Motor Show. Porsche->ke1, Skoda->ke82, and Seat->ke80 were also rumored to build models on the same platform, but a final decision has yet to be made: "Scale is important to a project like this. But with three different car makers working to a common goal, the chances look good."
