A development mule for the 2018 Porsche Cayenne has been spotted testing at the Nürburgring following a stint of running near the Alps.
The car is dressed in current-generation Cayenne bodywork, but beneath the familiar exterior sit new underpinnings because this mule is being used to test chassis components and settings.
Earlier development cars have been spotted running inside the Arctic Circle as part of cold weather testing.
Although the mules have all been dressed in current-generation Cayenne bodies, the finished next-generation model is expected to gain a more aggressive front-end treatment and sleeker tail-lights, as seen on the Audi Q5-based Porsche Macan.
Our sources also believe the next-generation model could gain an all-electric powertrain, as previewed by the Mission E, but Porsche has so far remained tight-lipped about the possibility.
Porsche has produced a new range of turbocharged engines for its latest 911 range and our sources suggest much of that technology development will be transferred into the large SUV. Its sister car, the Audi Q7, has recently gained smaller, more efficient engines across its line-up, giving some indication of what could feature in the 2018 Cayenne.
