Considering my car is bombed out in a shed somewhere, I'd be happy with any car—but given half the chance I'd love to see this Audi Q7, complete with all 62 speakers, in my garage.

It's the Audi Sound Concept, which sees the car manufacturer's engineers cramming in 52 mid-range speakers, five woofers and five tweeters into one of their small Q7 cars, with speakers hidden in the dashboard, ceiling and doors. Sound like overkill? It probably is—but Audi's used "wave field synthesis," an audio rendering technique which doesn't have many compatible audio tracks that are playable with the audio system, so this is very much a prototype showing The Future, if nothing else.

If the car ever does turn up on a showroom floor, good luck driving it away on holiday—there's no boot to stow your luggage, with most of it being used to hold the amplifier and cables.

What a shame only 32 tracks can be played on the system so far. If I was driving that baby, I'd crank up some Queen extra-loud.
I would love to hear what this car sounds like! Especially being that its an Audi concept instead of some aftermarket crap job.
