As I stated in another thread this Model 3 is a 3D model used for the photos in the supercharging blog post so may bear no resemblance to the real or planned or production model 3. That said it's a decent model that someone took the time to make, possibly from a CAD file or possibly modelled from scratch - who knows. It has the body shape, doors, door handles, nose, hatch and the glass roof looks to be accurate and even tinted - different to the S's in the photos (also 3D models obviously).
So here's my observation: there's a bump on the dash, behind the steering wheel. This cold house lights or instruments. Maybe indicator or warning lights, maybe speed, or maybe it's the 3D modeller being lazy and using a dash from a model he created for Ford . But this thing is definitely different from the Model 3 interiors we have seen before.
