The German automaker's Sound Concept adds 62 speakers -- five woofers, five tweeters, 52 midrange speakers -- into a Q7 with the aim of creating a physical principle known as "wave field synthesis." For the layman, this essentially means creating a nonlocalized virtual starting point for sound waves, driven by individually powered speakers. In even more layman's terms, it means that no matter your position in the car, or how much you move when you're in there, it sounds like you're in the ideal listening position.

The Sound Concept is the result of a five-year working relationship with the Fraunhofer Institute for Digital Media Technology in Ilmenau, Germany. And the great sound does have trade-offs. For one, most of the luggage space is taken up by amplifiers. Door handles must also be lowered, to accommodate the row of speakers above. However, for the audiophile-cum-car-buff demographic, this sound system may be the Holy Grail. A quote from Gizmag:

"When Gleim plays the sample, a sound like a thunderhead issues from the speakers – a mix of music, traffic noise and animal sounds. A female narrator guides the listener through the acoustic hubbub, dancing past the listener on the right and at other times on the left. The whole time the listener’s ears are surrounded by the sounds of driving cars and roaring lions. A marching band seems to march from side to side through the Q7 before finally a helicopter flies a lap around the cabin below the headliner."
