SPY PHOTOS: Porsche's New GT Coupe

Come fly with me

What kind of monster is Porsche developing? We have seen this Porsche Cayenne-based mule before, and every time we ask ourselves: What can it be? A Lamborghini SUV? A Bentley SUV?

We still don't know for sure, but this prototype is hammering around the "Ring" with a speed that makes even Michael Schumacher jealous. It is actually one of the fastest cars around the Nürburgring, and the noise it makes is so evil, it makes the hair on your neck stand. At first, Porsche only had two of these mules, but now you can get them in almost every color. We have seen it in gold, black, blue, green and red. Also, we now know a little more than before:

• First, these mules are rear-wheel-drive only.

• Second, they are built as light weight cars with no power windows and central-looking, plastic windows in the rear doors and backwards.

• Third, in normal cases the tires of a SUV are as wide in the front as in the back. But on this mule we can clearly see that's not the case. The rear tires are much wider.

So, is it going to be a Cayenne RS? Is it a project that Porsche is developing for another brand? Or could it be a new front engine sports car from Porsche based on the new Panamera platform? A 2 door coupe aiming at the BMW 6-series, Maserati GranTurismo and Mercedes CL disguised under a Cayenne body just to make sure we won't notice? Hopefully, we will get an answer to all these questions in a near future, and till then we will keep on speculating and enjoy pictures of airborne Porsches.

The photos are showing one of the test cars airborn at Nurburgring. It is the only car that is so fast in this spot on the ring that it gets all four tires off the ground, and when it accelerates it visibly burns rubber in a big dark cloud trailing behind.
