One winning attribute for the RX is its spacious cargo area. At 40 cubic feet with the rear seats up and 80.3 cubic feet with them folded, you'll be hard-pressed to find another two-row crossover — or perhaps even a three-row crossover — that tops it. Audi likes to compare its new Q5 crossover with the RX, but the Q5 packs just 29.1 cubic feet in back. The redesigned Cadillac SRX has 29.8/61.1 cubic feet.
