The sports coupe should arrive in late 2017 and may have a biturbo V6 under the hood.

A heavily camouflaged test mule for the next-generation Audi RS5 is once again on the road around the Nürburgring, and this fresh batch of spy shots gives us another opportunity to check out the upcoming coupe.

Like the previously spied RS5, the test car already looks ready for the track. It wears a mean-looking fascia with large intakes and has fender flares to fit the wider wheels. A tiny trunk lip spoiler is visible in the profile photo, and at the back dual exhausts poke out from each corner.

According to our spies, this tester is an early powertrain and chassis test mule. What’s under the hood is still a mystery, though. Rumors suggest Audi might switch to a biturbo 3.0-liter V6 with around 450 horsepower. The next RS4 and possibly a version of the R8 would also use the engine.

If you’re itching to get an uncamouflaged look at the ultimate version of Audi’s sports coupe, be very patient. The standard A5 debuts on June 2, and then the already spied S5 needs to hit the road. Don’t expect the RS5’s arrival until late 2017. The advantage of the long wait is that the engineers at the Four Rings still have plenty of time to make the next generation as fantastic as the last one.
