23. Audi R8 GT Sport
We haven't seen a "sport" label on an Audi since 2005's TT quattro. We're hoping to see it again on the R8 GT. Test rides have been spotted. Rumors are flying. And, fingers crossed, we'll see this powerful vehicle at the tail end of 2013. If tradition holds, the "sport" designation could also mark the end to this generation of R8s.
