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.

Bentley to debut Continental GT V8 S and GTC V8 S at Frankfurt motor show

If you've always felt that the Bentley Continental GT V8 was a little short on power, then Bentley has a new model for you. Two new models, actually: the Continental GT V8 S and GTC V8 S, and Bentley has released details and images a week before their public debut at the 2013 Frankfurt motor show. Bentley engineers have managed to squeeze a bit more power out of the 4.0-liter twin-turbo V8 engine, bringing the horsepower rating from 500 up to 521.

Young drivers at risk from poor tyre care

YOUNG DRIVERS are putting their lives at risk by not looking after their cars’ tyres. A survey by Tyresafe and insurer Ingenie has found that more than a third of young drivers aged 18-25-years old had never checked their tyres for tread depth and a quarter had not checked the tyres on their car for correct pressure ever. The survey found that better education is needed to tell young drivers of the important of looking after the tyres on their car.
