That can extend by up to 5.3 inches, when the auto is driving at speeds of over 56 miles per hour.
The first Cayenne Coupe units are expected to arrive in U.S. showrooms this fall with a starting price of $76,550 (including $1,250 freight).
At the back, there are redesigned rear doors and rear quarter panels.
A leaked sketch of the upcoming Porsche Cayenne Coupe has surfaced on Instagram, previewing a model expected to be revealed prior to the Frankfurt motor show this fall - perhaps as early as this month.
The new four-door arrives this fall
Cayenne Coupe variants boast Porsche Active Suspension Management (PASM) as standard, as is the Sport Chrono Package and 20-inch wheels. In short, there will no shortage of spoilers attached to the bodywork of the new Cayenne Coupe, perhaps reflecting the stylistic tastes of the SUV coupe audience.
The more potent $254,000 Cayenne Turbo Coupe has a 404kW/770Nm 4.0-litre twin-turbo V8, which cuts the 0-100km/h time down to 3.9 seconds, and raises the top speed to 286km/h. A fixed panoramic glass roof with a shade is standard equipment, but Porsche is introducing a carbon fiber roof option exclusively for the Coupe that looks pretty rad. Two engines will be offered. That'll be good for 335 horsepower and 332 lb-ft of torque, enough to do 0-60 miles per hour in 5.7 seconds. The Cayenne Turbo Coupe uses the 4.0-liter twin-turbo V8 producing 541 horsepower and 567 pound-feet of torque, bringing the 0-60 miles per hour time down to 3.7 seconds.
"Of course we are discussing the electrification of the Cayenne - but we are doing the same for every model line", said Wolfgang Butschek, Porsche's manager for sales and marketing. No slowpoke, it gets from a standstill to 60 miles per hour in 3.7 seconds, and tops out at 178 miles per hour. Top speed, meanwhile, rises to 178 miles per hour. A full bench seat can be ordered as a no-cost option, but then you may as well as go the whole, erm, hog and order the full Cayenne to go with it. Either way, the rear seats are 1.18-inches lower than their counterparts in the Cayenne, so that headroom is still preserved despite the lowered roofline. Only two adults will fit in the rear, unlike the Cayenne, which can fit three across in the rear seats. In the Cayenne Turbo Coupe, those numbers dip slightly to 21.2 cubic feet and 53.3 cubic feet respectively.
