New review from cars.com does say that the 2dr definitely has less leg room.Just editted my previous response and added this (which helps prove it out):
The difference of volume of behind the front row and second row imply rear seat volume of:
2 dr - 28.7 cubic feet
4 dr - 42.0 cubic feet
So thats a 32% loss over the 4dr.
Lets look at the width difference to back into the length -
Comparing rear hip - 43.3" vs 54.8" = 21% loss
or comparing rear shoulder - 51.8" vs 56.5" = 8% loss
So figure as a midpoint between hip and shoulder, is a 15% loss in width. The rest of the 32% loss in volume MUST come from legroom. The 4 door legroom should definitely be longer than the 2 dr. Not identical at 36.3"
