Porsche has been pumping out special models for many of its models recently, and the Panamera sedan could be next. Our spy photographers were able to capture a test car during development with center-lock wheels, which could suggest a hotter variant is down the line. Porsche typically reserves center-lock wheels for their highest-performance vehicles such as their GT, Turbo GT, GTS, and Turbo S models, and seeing as the Panamera already offers the latter two models without center-locks, the new photos seem to suggest that this could be a new GT variant. These center-lock wheels have a unique design not found on any of the other prototypes, suggesting they could be exclusive for this model.

Of course, there is the chance that the new Panamera might just have center-lock wheels on the GTS and/or Turbo S models, but a new rear diffuser similar to the one on the Cayenne Turbo GT seems to suggest that Porsche might be cooking up a Panamera Turbo GT as well. Additionally, the unfinished exhaust pipes at the corners of the bumper insinuate that might not be their final location, and instead we might see them shift to dual center pipes in the diffuser just like that aforementioned Cayenne Turbo GT.

 

Up front, there’s a new bumper design with larger, squared-off openings, and while it does somewhat resemble that of the Cayenne Turbo GT, all the other Panamera prototypes we’ve seen so far have had that same or similar fascia, and they would theoretically be lower-trim models. In all likelihood, this is probably just what the front-end design of the new Panamera will look like. That being said, this car is the only prototype we’ve seen so far with red brake calipers, which helps further the notion that this might be something special.

If the car truly is a Turbo GT, we could potentially expect an uprated version of the Panamera Turbo S’s 4.0L twin-turbo V8, as that was what Porsche did to the Cayenne Turbo GT. In that case, the car would make 631 hp and 850 Nm of torque. Should this be something other than a Turbo GT, though, it’s likely that its engine will remain similar to what’s currently offered in that respective model, as this new Panamera is expected to be more of a revision than an all-new car.
