The RDX may have supplanted the MDX as Acura’s best-selling model, but Acura hopes to put the their mid-sized crossover back on top with the all-new 2014 MDX. To show us how they plan to do that, Acura invited us to Oregon to sample the new MDX for a day around Newberg. Even without the snazzy trip it’s easy to see that regaining the Acura sales crown shouldn’t be difficult. After all, the current MDX is Acura’s second best-selling vehicle and despite being seven years old (ancient in the auto biz) the MDX is still the best-selling 7-seat luxury SUV in America and the second best-selling mid-sized SUV/crossover period. How does one redesign success? Carefully.
