Audi R4: Is it a high-performance baby R8 or a fuel-efficient roadster?

The Audi R4 has become a total mystery to us – it’s slowly becoming one of those cars that we keep hearing rumors about and keep seeing photo renderings of, but never actually see it enter production.

Last we heard anything about the Audi R4 it was reported that baby version of the R8 will be build on a brand new platform, sitting above the Audi TT. It was rumored that a new 2.5L 5-cylinder engine producing above 300-hp could be found under the hood.

Latest rumors suggest that the car will be an Audi version of the Volkswagen Concept BlueSport recently unveiled at the 2009 Detroit Auto Show. The Concept BlueSport is powered by a 2.0 TDI common-rail injection making 180-hp allowing for a 0 to 62 mph time of 6.6 seconds. A production version of the BlueSport is expected to arrive sometime in 2011.

Whatever the Audi R4 may be, here are the latest round of photo-renderings for it.
