My insurance agent had one of the late model Nissan Z cars and really liked it. He is probably 6'3" or so and never mentioned it being too small. Isn't the Infiniti Coupe a bit longer, with a bit more room?
I'll have to rescind my suggestion. I just read a review of the new coupe, and it said that headroom is compromised in the pursuit of sleek lines. As in if you're over 6', you probably won't like it. I'm 6', and have no issues in the sedan though.
As for dimensions, the G's are a foot longer in wheelbase, and 400 lbs heavier. No difference in track width. Especially in the sedan, you're getting a good chunk of that wheelbase equating to more room in the passenger compartment. I've sat in the rear seats, and if the forward seats are not all the way back, it's tolerable, though certainly not luxurious.
