Audi Q7 Sound Concept rocks CES 2013 with 24 speakers and “3D sound”

By Stephen Edelstein Published January 9, 2013

Audi is on a roll at this year’s Consumer Electronics Show (CES). The German carmaker has already unveiled a new infotainment system based on a modular NVIDIA Tegra processor, and futuristic tech like a 3D infotainment display and laser-equipped safety system. How do you top that? How about by cramming 24 speakers into an SUV?

The Audi Q7 Sound Concept previews high-end audio that will eventually make its way into production Audis. Based on Audi’s seven-passenger crossover, the Sound Concept sports the aforementioned 24 speakers and 1,800 watts of power. A stock Q7 equipped with the Bang & Olufsen audio option has 19 speakers and 1,400 watts of power.

Perhaps trying to match the MMI engineer’s 3D display, Audi’s sound engineers gave the Q7 Sound Concept “3D sound.” This system adds extra speakers (made by Bang & Olufsen, just like the stock Q7’s speakers) into the A-pillars, added an extra B&O amplifier, and finished off with software from Fraunhofer.

By moving the speakers higher, Audi hoped to get more even sound coverage. In a normal car, sound emanates from the front, rear, and sides of the passenger compartment, but since speakers are usually placed below the window line, the sound is only coming from below the passengers’ ears.

Since passengers in the Q7 Sound Concept are basically surrounded by speakers, they are supposed to get a more realistic, immersive experience. With all that hardware, it can also be a very loud experience.

The 3D sound system accepts accepts MP3, CD, and radio input, although it may require an adapter for wax cylinders.

Audi says 3D sound will be an option on upcoming production cars, but not until at least 2014. Like the current B&O system, it will be an extra-cost option on the Q7, A6, A7, and A8.

Plug-in hybrids are becoming more popular. Why? And will it continue?

There's a lot of talk about the idea that the growth in electric car sales has kind of slowed a little. It's not all that surprising -- EVs are still expensive, early adopters all have one by now, and they're still new enough to where there aren't too many ultra-affordable used EVs available. But plenty of people still want a greener vehicle, and that has given rise to an explosion in hybrid vehicle sales.

That's especially true of plug-in hybrid vehicles, which can be charged like an EV and driven in all-electric mode for short distances, and have a gas engine as a backup for longer distances or to be used in combination with electric mode for more efficient driving.

Nearly all current owners of electric vehicles (EVs) are either satisfied or very satisfied with the experience, and 92% of them plan to buy another EV, according to a survey by the Global EV Drivers Alliance.

The survey of 23,000 EV drivers worldwide found that only 1% would return to a petrol or diesel car, while 4% would opt for a plug-in hybrid (PHEV) if they had to replace their car.

Trump team in sync with Tesla on ending crash-reporting requirements, report says

The transition team of President-elect Donald Trump is planning to end existing car-crash reporting requirements to safety regulators, according to a Reuters report.

The report cites a document obtained by Reuters that lays out the transition team’s 100-day strategy for automotive policy. In the document, the team says the crash-reporting requirement leads to “excessive” data collection, Reuters says.
