The Nürburgring circuit is always flocked with test mules and the latest coming from the spy photographers is the upcoming Audi RS3 that sports an unique orange color scheme. Compared to the A3, the new Audi RS3 is a pretty different looking commuter — a visible difference in these spy flicks are the larger air intakes on the modified front bumper. The RS3 is indeed directly comparable with the S3 Sportback in terms of body. While there are no official specs for the RS3, it is widely believed that it will come with the same 340 PS 2.5 liter, turbocharged 5-cylinder engine as in the Audi TT RS. We expect to see a finished version of the Audi RS3 at the Paris Motor Show in September.
