I have been scratching my head thinking about what this is as well. I was thinking maybe an intake resonator but it looks a bit complicated to be that.
Maybe some kind of mini heat exchanger to reduce IATs before the turbo? There are water lines right under it, but it is hard to tell if it is...
hmm, door mounted side view mirrors, new hood scoop/vent design but no fender vents. I do like the new rear wing design, as well as the headlights being quad beam.
