I've heard rumors there will be vibrating massage seats to go along with the heated seats. They will be powered by a subwoofer mounted under the driver and passenger seats (where else could they place 17 speakers!?)
This has the info on the Genesis Sedan audio system, but I have yet to see the Coupe system defined.

"Hyundai Genesis joins the Rolls Royce Phantom as the only automobile to offer a Lexicon-branded audio system featuring LOGIC 7(R) technology, which creates a wide and extremely satisfying sound stage for the system. "
The only thing I can find on the Coupe is that it has an Infiniti sound system, with USB and a 3.5mm AUX input.
