Inside the cabin, there’s less cargo room than the X3 by about 10 cubic feet, but clearly cargo room was down on the list of must-haves for the RDX. This is one crossover that’s about convenience and cornering, as opposed to cargo. As with its utter inability to do anything off-pavement due to a paltry seven-inch ground clearance, it’s a performance premium you pay for the RDX. If you care about cargo room so much, go buy yourself a sexy new MDX. Funny thing, though: Where the RDX surprises is in its cabin space. It’s quite roomy in front and back for legroom and headroom. Our driving partner was clearly over six-feet tall and he got behind the wheel easily, without complaint.
