CES: Cranking up Harman's QuantumLogic 3D surround-sound system

Yesterday we reported how Audi was readying a lavish 3D sound experience with 23 speakers and 1,400 watts of goosebump-inducing audio power. Not to be outdone, Harman had been quietly developing a system of its own: Quantum Logic 3D brings together 25 speakers and more than 2,000 watts of Tubthumping power to a new car near you, like driving inside Phil Spector's Wall of Sound. Sitting inside the demonstration BMW 7-Series that Harman painstakingly lifted into the Studio at the Palms, Global Audio Engineering vice president Phil Muzio explained, "great music is delivered in stereo, yet our consumer research indicates that people enjoy surround sound." QuantumLogic 3D's surround sound expands beyond the boundaries of the vehicle's cabin, providing "a sense of detail and spatial placement that you don't get in stereo." Five height component speakers mounted in the corners of the headliner, and above the rearview mirror, elevates audio beyond the confines of the roof, "almost like you're in a convertible," said Muzio.

Mercedes S Class production cut as sales fall

Mercedes is cutting production of the range topping S Class to a one shift operation as sales fall ahead of the new 2013 S Class. But there are now plenty of signs that even premium car makers are not immune from the economic climate – particularly in Europe – as sales start to slide. We recently commented that Jaguar sales are not as strong as they were and now it seems Mercedes is starting to feel the punch as sales of the range-topping S Class falter.

R8 e-tron electric supercar will be built, Audi says

The Audi R8 e-tron is back on: Audi has backtracked on an earlier decision to cancel production of the zero-emission supercar and will now push ahead with small-scale production two-seater, Autoweek can confirm. The decision is part of a number of sweeping changes made to Audi's research and engineering operations since the arrival of its new head, Ulrich Hackenberg. Citing recent advances in lithium-ion battery technology that has reportedly increased its range from an original 134 miles to close to 250 miles, high-ranking insiders at Audi's headquarters in Germany suggest the R8 e-tron will now go into limited production during the latter half of 2014.
