It's being touted as Acura's new direction and, as such, it's an interesting case study in how a company responds to the ever-evolving competition.
I was on Acura's junket to San Francisco when the original RDX came out. It was Acura's first turbo four, and it was a wonderful SUV that featured what at the time was probably the best audio system I'd experienced in a vehicle.
That ELS audio system is still around, kind of, but it has also marched along with the marketplace--which to me is a double-edged sword.
