The second-generation RDX is so different from Acura\'s first foray into the small-crossover segment, it could almost justify a new name. But Acura doesn\'t want to further confuse potential buyers, so instead Honda\'s high-end brand is retaining the RDX badge but rolling out a significantly different vehicle. What\'s so different? Where the original RDX in 2007 was deliberately targeted at what the company called \"urban achievers\"--typically competitive and highly active 30-year-old single males pulling down $100,000 annually--the 2013 model intentionally changes gears to go after the people who actually bought the car: pre- and postfamily couples. So, instead of chasing some hotshot enthusiast with a tautly suspended turbo four-cylinder ute, Acura has softened the 2013 RDX while upgrading the powertrain to a V6 and improving the interior. Side by side, the two models show some exterior variance, but it\'s minor compared with the changes underneath. Refinement is way up compared with the previous model: The ride is smoother and softened thanks in part to a longer wheelbase, with a suspension that feels far more predictable and controlled, while the steering is weightier and more precise. The V6 is light-years quieter and more refined. Gone is the turbo whine, replaced by hearty torque across the rev range. The V6 might not be any more responsive overall, but the lack of turbo lag gives the RDX a much more luxury-performance feel. All of that, with no loss of fuel economy, thanks to the imperceptible action of Honda\'s multicylinder operation that uses three, four or six cylinders depending on power demand. Inside, the center stack is much more intuitive, with climate controls, audio and navigation buttons grouped together. The steering wheel is thicker and plusher, which adds to the more firm feel of the steering. Paddle shifters are perfectly located on the steering wheel but emit an annoying and unnecessary metallic click with each shift. The seats are plusher while remaining supportive, but Acura has always been top-notch in seat trim. The twin-cockpit layout with a joining crossbar of trim makes for a nice look. Oddly, there seems to be a touch less legroom in the front seats, so if height runs in your family, check that out before buying. But overall, the interior is well appointed and premium in look and feel, with the little things such as padding added to the bottom of cubbies to prevent items from rattling against hard plastic. For the 2013 RDX, it\'s all about mature competitor versus boy racer. If you like your premium crossover to reflect your childless but successful station in life--be that double income, no kids early in your career or empty-nester headed for retirement--the RDX is now a much closer match to your lifestyle, while still being a little distinctive. It\'s only a five-seater, so if you think you\'ll be hauling a passel of nephews and nieces or grandkids, you might need to step up to the three-row MDX. But thankfully, you no longer have to give up big chunks of luxury and refinement if you do choose Acura\'s entry crossover.
