Porsche seems to be working on a more powerful ‘S’ version of the Macan SUV which has been spied testing at the Nurburgring motorsports complex in Germany.

Currently, the most powerful variant of the Macan is powered by a twin-turbo V6 3.6-litre engine that delivers an impressive 294 kW. However the new prototype seen undertaking the Nordschleife in the video below is likely to be a Turbo S variant with 316 to 324 kW of power from the same motor.

The Porsche Macan Turbo S is likely to complete the 0-100 km/h sprint in about 4.6 seconds (4.4 second with the Sport Chrono pack), while the Turbo model does the same run in just 4.8 seconds. Top speed is expected to increase just a bit more from the current Macan Turbo’s 266 km/h.

There’s not much we can say about the design, but it seems the camouflaged headlights hint at a better LED setup.

An official launch of the Porsche Macan Turbo S is expected sometime in 2015. We’ve been invited to the South African launch of the Porsche Macan and we’re looking forward to getting behind the wheel of the baby Cayenne. How much will thePorsche Macan cost? We have the Macan pricing already, check it out here.
