It's likely the rear seat room won't take priority like it does in a sedan. I would expect to see rear seat knee room comparable to the MINI or Fiesta or Infiniti G37 coupe or BMW 1-er; all of which are knees-in-the-front-seatback tight even for a 5'9"er. No bodybuilders or footballers in back, and those that do fit will likely only tolerate it for a couple minutes.

You have to remember the dash-to-axle ratio is aggressive, with the front seats pushed relatively far rearward. Add in the low roof and sloping fastback and you end up with not much volume for rear seats.
