Upcoming SUV coupe hits the 'Ring during performance testing.

The Porsche Cayenne Coupe has been spied again at the Nurburgring, ahead of an anticipated production reveal sometime next year.

It's been two years since we saw the first prototypes for the fastback Porsche SUV, and it appears the new body style is edging closer to production.

Up front the Cayenne Coupe will share much of its sheet metal with its wagon-bodied counterpart, with unique body panels from the B-pillar rearward.

In terms of shape it appears the Cayenne Coupe will draw some design inspiration from the smaller Macan and the Panamera sedan, with a sloping roofline and fastback tailgate.

Fake tail-light stickers cover the actual units, though we'd expect the Cayenne Coupe to sport the slimline LED clusters rolling out across the company's range.

Power will likely come from a range of turbocharged six- and eight-cylinder engines as per the regular Cayenne, along with a pair of plug-in hybrid models – including the 500kW S E-Hybrid powertrain offered in the Panamera.

The Cayenne Coupe will join the related Audi Q8 and Lamborghini Urus crossover coupes in the Volkswagen Group's line-up, all sharing the MLB Evo architecture and utilising the same engine family.

In terms of timing, we're expecting the Porsche Cayenne Coupe to make its production debut sometime in 2019, though we could see it surface very late this year.
