The center-lock wheels and the yellow brake calipers (these signal the presence of PCCB carbon-ceramic brakes) should mean this example is a Turbo S, since the said features are standard on this derivative, while coming as options on the "normal" Turbo.
The big question revolves around the engine served by those rear-arch air intakes. As such, we could see Zuffenhausen retiring the twin-turbo 3.8-liter boxer animating the 991 and introducing a new engine. The latter could be based on the also-turbocharged 3.0-liter unit in the 992 Carrera (S), as is the case with the N/A 4.0-liter boxer found at the top of the 718 mid-engined range.
As for the 8-speed PDK transmission replacing the 7-speed gearbox of the retired model, this is almost a certainty. Of course, there are also details that have yet to be revealed, such as the programs of the tranny (this should be more aggressive than the 8-speed PDK on the Carrera, or the way in which the AWD system splits the torque).
From drag racing to the Nurburgring (think: 7:25), the 992 Neunelfer Carrera S has proven it can run with supercars, while this turns into a GT once the driver stops abusing the throttle, as I found out while reviewing the rear-engined toy. So we can only imagine the stellar assets of the new Turbo!
