Ever since the initial complaints about the trunk opening size on the Model 3 concept, I'm wondering what changes the final production model will bring. I think a full-fledged hatchback is pretty much out of the question at this point. Here are the three possibilities I've hypothesized: 1) Larger cut-out with a deeper cut into the bumper, and slightly less rear glass taper and a longer decklid profile. 2) Partial lifting rear glass, but fixed rear bulkhead crossmember. 3) Two-piece opening with "tailgate" on lower bumper. My money's on 1, from a simplicity standpoint. Thoughts?
