Audi e-tron Detroit Concept – Click above for high-res image gallery

If you're wondering what the likelihood of Audi building a production version of its new e-tron Detroit Concept Car (yes, that's really its official designation), our sources at Audi indicate that a version of the coupe is likely to go into serial production as the oft-rumored R4.

The German automaker is apparently looking to design a smaller modular platform leveraging the expertise it used to develop the front-engine sedan platform that underpins the new A8 and forthcoming A7, among others. The new mid-engine architecture will likely find homes in a number of Volkswagen Group properties, including a production version of the Concept BlueSport, and perhaps even the next-generation Porsche Boxster/Cayman.

While the e-tron show car is a battery-powered electric vehicle, the production model is likely to be available with either an electric motor or conventional internal-combustion four-cylinder variants.

Given the fact that VW intimated last year that a production BlueSport could be produced at around $25,000, we're anticipating that the Audi R4 will slot in under the TT in the low-$30,000 range, as the 2010 TT presently starts at $37,800.
