The RDX is not aging well.
Exactly five years after I first drove the Acura RDX, I find that it is not aging well. The turbocharged engine delivers decent power, but it's not linear in its delivery, and the five-speed automatic is a dated device. The ride-and-handling balance is ho-hum, and the suspension crashes over bumps. The steering is dead on-center. There's a distinct lack of a "premium" feeling to the RDX, especially when compared with the newer entries in this segment like the Volvo XC60, the Audi Q5, the Mercedes-Benz GLK, and the BMW X3. Heck, there are small crossovers from non-premium brands that feel more of-a-piece than the RDX does, like the Chevy Equinox, the Hyundai Santa Fe, and the Volkswagen Tiguan. The RDX is definitely overdue for a re-do.
