Someone correct me if I am wrong, but I think TSX's have the federally allowable 2.5 mph bumpers, to Euro standard, like BMW and Benz's (and Audi TT's and few others) do. Right? Check the Acura spec sheet; the usual mention of 5 mph bumpers is missing on the TSX sheet. To our benefit is the trim beauty of it; no stupid overhangs like on a Mazda 6 or so many other US market cars that have been modified (IS300 same thing; in Europe the rear end is nice and flat like a TSX. Even Audi uses bigger rear bumpers on its US market cars except for the TT).
