Although the brand-new Macan is already on sale in the United States, Porsche->ke1 has yet to expand the lineup to include as many models as the Cayenne->ke212 range. But that's likely to change next year, as the Germans are testing what appears to be a more powerful iteration of the Macan. We're obviously talking about the Turbo S, which was spotted in prototype guise on the Nurburgring->ke999 track.

How do we know that? Well, although the crossover is slightly camouflaged, its quad, trapezoidal exhaust tips and front bumper design are of Macan Turbo origin. Then there's the way the black Macan dances around the legendary course. The crossover acts like a sports car->ke506, attributes seen only in the case of Porsche SUVs, and slices through the curves with great precision and minimal slide.

The exhaust note also suggests we're listening to a turbocharged, 3.6-liter V-6 engine. That's the same powerplant offered in the Macan Turbo, but we expect the Turbo S to benefit from more than 400 horsepower. At least 430 ponies if you ask us, coupled with around 440 pound-feet of torque. Enough for the Turbo S to render its competitors obsolete, at least until BMW->ke178 and Audi->ke178 come to their senses and release M and RS versions of the X3->ke255 and Q5->ke1666, respectively.

Expect the Porsche Macan Turbo S to go on sale for the 2016 model year in the United States, with pricing set to start from around $90,000. Meanwhile, enjoy the Turbo S prototype stretching its legs around the "Green Hell" in the video->ke278 above.
