Most of us expected the upgraded Audi R8 to makes a special appearance at the previous Frankfurt Auto Show, but unfortunately the luxury sports car speeded past the international showroom floor. But TC Concepts was putting some finishing touches to the speedster, creating its own version of the Audio vehicle dubbed the R8 Toxique, which garners a number of presentable facets from larger air intakes to massive, slim rubber tires. The back sports a new racing wing made from carbon fiber, along with a massive diffuser built from light-weight materials. Sounds cool? The Audi R8 Toxique is rumored for a 2012 release.
