I just downsized from a 2011 MDX to 2014 RDX AWD and am happy with my choice. Getting about 27mpg in RDX vs. 19mpg in MDX. A little disappointed about losing SH-AWD but a good trade off for fuel economy. New RDX looks sharper and feels roomier than its predecessor (my brother has the older model), handles corners nicely, quiet and luxurious interior, and new keyless ignition start is a plus that wasn't available in the 2011 MDX. My biggest and perhaps only complaint is that the E-break is too close to my leg! Smashed my shin into it about three times in the past three weeks that I've driven this car. Overall, a spritely and spirited vehicle.
Keyless ignition start, power hatchback, new streamlined body, easy fold down rear seats
Emergency break too close to driver's leg, steering a tad too soft
