For 2013, the RDX makes some strides over the previous model in this regard, and some inroads against the competition as well, with a very competitive price. For a given dollar amount, chances are the RDX will be the best-equipped luxury crossover available. But there are some compromises.
The front seats are comfortable and relatively spacious, with enough adjustment to fit both taller and shorter passengers, though the length of the seat bottoms is a bit short for longer-legged drivers. The second row is more cramped, but still suitable for all but those in the six-foot-plus club.
Materials are generally very good, equivalent to Lexus in most regards, and even BMW in many aspects, though plastic plays a more dominant role on the dash, and the fit and finish aren't quite as tight and tidy as the Audi Q5's. The cabin is well-laid-out, too, with cubbies and nooks for storage, ergonomically-placed controls (with the exception of the large central controller for the Acura navigation/infotainment unit on equipped models), and generally well-built, solid-feeling panels in all locations.
Ride quality has improved significantly over the previous RDX, and actually matches or exceeds even the BMW and Audi offerings, blending a smooth, comfortable ride over rougher roads with a capable and confident feeling in sportier moments. Noise, likewise, is very low--whether road, wind, or tire.
