The car in these photos appears to be lightly disguised as a Cayenne. The tail light covers are fake and intended to hide the fact that this is a long-roof version of the Panamera sedan and not an SUV. The Acid Green brake calipers also give away the fact that this model is likely based on the new Panamera 4 E-Hybrid – one of the best driving sedans around, hybrid or not.
The photos here are less about the newly-exposed skin or the green brakes, but rather more about how close the Panamera Sport Turismo is to reaching production. Don't expect Porsche to keep the camouflage wraps on the car much longer.
