Previously spotted in the American desert, another Audi RS5 prototype has made its way to Germany's Nurburgring Nordschleife. Once again, sending mixed signals, the RS5 is sporting the quad exhaust pipes from its less powerful S5 sibling, as two large oval pipes are normally characteristic of the ultra-sporty RS series.
Therefore, we are left with two possibilities to consider. Either a meaner looking RS style front bumper upgrade is in the works for the S5, perhaps for greater stylistic differentiation from the rest of the A5 range, or it is indeed the RS5 using an S5 test mule body.
With an expected debut in Detroit in January with a possible 450hp 4.0-liter turbocharged TFSI V8 engine, we hope to see new prototypes soon looking more production ready with bigger wheels and flared RS style fenders.
