Ford's upcoming high-performance, SVT-tuned Mustang has been spotted on the Nurburgring.

Our spy photographers have spotted Ford's Shelby GT500-replacing performance Mustang undergoing high-speed testing at the Nurburgring. Ford's flagship Mustang is expected to launch for the 2016 model year.

Outfitted with the most revealing camouflage of any prototype we've seen thus far, the SVT-tuned 'Stang - likely to be called the GT350 - is easily identified by its beefy wheels and tires, enormous cross-drilled brake rotors and quad exhaust outlets. The track also appears to have been widened compared to the standard model, and a menacing-looking front fascia is part of the package, too.

We don't know for sure what engine will power the GT350, but a naturally-aspirated 5.2-liter V8 appears to be the leading candidate. Although such a mill likely wouldn't be able to match the 662 horsepower provided by the current Shelby GT500's supercharged 5.8-liter V8, a significant weight reduction should ensure the GT350 is no slouch in the performance department.
