Porsche has finally bitten the bullet and joined the SUV-coupe party with a fastback-roofed derivative of its Cayenne all-terrainer. The new model addition was revealed at an exclusive media event in Stuttgart — rather than the recent Geneva motor show — and wheels was there to eyeball the Cayenne Coupe in the metal.

It’s no surprise the Zuffenhausen carmaker has tossed its hat in the ring in this genre as BMW and Mercedes have been cashing on healthy demand for the X6 and GLE Coupe respectively, and Audi has also recently entered the fray with its chop-top Q8.

In line with its premium orientation, the Cayenne Coupe — which sits about 20mm lower, 80mm longer and 18mm wider than the regular model — will command a slight price premium over its existing sibling when it launches here in October. The entry-level 3.0-litre V6 turbo kicks off at Dh335,900, with the flagship 4.0-litre twin-turbo V8 starting at Dh598,700.

The base model V6 kicks out 335bhp/450Nm, enabling the six-cylinder Cayenne Coupe to sprint from 0-100kph in 6sec and hit 243kph flat out. The range-topping V8-powered Cayenne Turbo Coupe serves up a 542bhp/770Nm punch, rocketing it to 100kph in a supercar-rivalling 3.9sec. Should you have access to a private road or racetrack, you can reach a v-max of 286kph.

As you can glean from the accompanying pics, the main visual changes are at the rear, with its sharply tapered roofline and adaptive rear spoiler that’s part of Porsche Active Aerodynamics (PAA). The spoiler extends by 135mm at speeds of 90kph and up, which Porsche claims keeps the rear end glued to road at high speeds.

The rear seats in the Coupe are set 30mm lower than in the standard Cayenne to ensure headroom isn’t compromised by the plunging roofline. Luggage capacity is 625 litres with all the seats in place, but folding down the rear pews boosts storage space to 1,540 litres, which means the new Cayenne derivative still offers plenty of utility.
