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.

Mazda 6 launched at 2012 Moscow motor show

Mazda has unveiled its new 6 saloon at the 2012 Moscow motor show – a nod to the significance of the Eastern European markets for the Japanese car maker. This third-generation Mazda 6 will be the second model in Mazda’s line-up to feature both its suite of innovative SkyActiv drivetrain and chassis technologies and the company’s ‘Kodo – Soul of Motion’ design language. That’s a clunky design title, but the new 6 is anything but - it’s a handsome looking car in our eyes, and takes its riffs from the Mazda Takeri concept first seen at the 2011 Tokyo motor show.

Aston Martin V8 Vantage S: The Video

Aston Martin V8 Vantage S on track at the Ascari Circuit in Spain We’re always up for a bit of Aston Martin goodness, so we were more than happy to report in January that Aston Martin has added a bit of extra oomph to the V8 to create the Aston Martin V8 Vantage S. To be honest, there’s not a huge amount of extra power on the Vantage V8 S – just 10bhp – but there are a chunk of tweaks that make it very appealing, including a new seven speed Sportshift ‘box, sharper steering, better braking and a bit of suspension tweaking to make the V8S that bit more aggressive. All this new V8 S goodness was served up at the Geneva Motor Show last week, but we got a bit sidetracked with the new Aston Martin Virage – or DB9 Ghia – in a marmite shade of orange hogging AM’s Geneva stand.
