First mules caught, in surprising level of details:
Well, whilst the body is still unmistakably Mk. VII, the wheelbase is visibly longer, and the rear overhang will also likely grow a bit, given how the bumper is shaped, makes sense given how the whole segment is growing in size; It also shows that rumors, the Ml. 8 might be a warmed up reskin like the Mk. VI was were wrong. Even if it will continue to ride on the MQB chassis, it will have an all new body (even though it might end up looking like a facelift anyway)
Inside, we can see digital instruments, and, rather interesting, no center Screen, but some hard buttons where the current model has it's infotainment, indicating that the infotainment is either going where the air vents are now (and those will be relocated very low like in the Touareg), or that it might get a Audi TT like "virtual cockpit only". The shifter also seems to come form the Touareg resp. high end Audis.
The tartan seats, 4 cylinder engine and IRS plus actual double exhaust make me think this might actually even be a GTI mule, or a higher spec version at least;
