If you've driven the previous Acura RDX, you know the definition of compromise. While it was, in many ways, ahead of its time, the RDX was rough, balky, and awkward as much as it was peppy, fun, and high-tech. Times have changed.
The 2013 Acura RDX doesn't look all that much different from the last on first glance. Nonetheless, it's all new, with different exterior and interior styling, a new powertrain, and a vastly different character--and it's aiming at a new target market.
As a member of the previous RDX's target market, I understand why it didn't succeed. Late 20s and early 30s professional men with a taste for both luxury and sport sound like good buyers. We're not. We buy modern classics gently used, we buy sport and forsake luxury, or we buy above our means and cut corners elsewhere. We don't make the compromise the last RDX required.
Disclaimer: Acura flew me out to a pretty sweet resort in Scottsdale for this drive, put me up for a couple of nights, and fed me surprisingly well. Despite all of that, I managed to keep my wits about me.
The new RDX may succeed where the last did not, as it requires far fewer compromises. In maturing into a more complete vehicle, it has also set its sights on younger pre-children couples, older empty-nesters, and those between that don't need as much kid-and-gear-wrangling capacity.
