Porsche is expected to reveal a refreshed version of the 991 Series 911 at the upcoming IAA Frankfurt Motor Show. This is it, apparently, the Porsche 991 Facelift featuring revised styling and upgraded mechanicals.

Spotted at the Hockenheimring race track in Germany, most likely on a break from punishing performance tests, this Porsche 991 Facelift prototype looks unfinished. But the main styling features you see on this car will be used on the final version.

Chief among these features there is the new retro-inspired engine cover, new taillight graphics, revised bumpers with larger air intakes up front and a new diffuser with dual tailpipes in the middle out back. The rest of the exterior appear to be the same as the existing version.

Porsche 991 Facelift also comes with a mildly revised interior boasting a 918-inspired steering wheel and a, seemingly, larger main display. The quality of the material and the fit and finish of the 911’s cabin have always been top-notch, so there probably was no need for upgrades in that aspect.

It remains to be seen what Porsche has in mind for the new 911 in terms of performance. Most likely the existing Carrera and Carrera S model will get a boost in power, while an all-new hybrid variant will be added to the range.
