Test your car's audio quality with iTunes playlist

General Motors audio engineer Matt Kirsch, who did the sound work for the Chevrolet Cruze, has developed an iTunes playlist that helps drivers test their cars' audio quality. The “10 Songs for an Audio ‘Test Drive'” playlist includes: “Don't Know Why” by Norah Jones “Diamonds and Rust” by Joan Baez “No One” by Alicia Keys “Hotel California” by the Eagles “Boom Boom Pow” by the Black Eyed Peas “Rock That Body” by the Black Eyed Peas “Hide and Seek” by Imogen Heap “He Mele No Lilo” by Mark Keali'i Ho'omalu (from Lilo & Stitch) “Bird on a Wire” by Johnny Cash “Packt Like Sardines in a Crushd Tin Box” by Radiohead While “Boom Boom Pow” and “Rock That Body” should have accurate and powerful bass beats, “No One” and “Bird on a Wire” should feature clarity in the vocals. Kirsch's playlist is available for download at http://tiny.cc/c2ach.

New Routemaster bus hits London streets

The very first new Routemaster hybrid bus began its first day of service in London today. The bus, whose exterior and interior were designed by Londoner Thomas Heatherwick, retains the distinct character of the old Routemaster – British as the London taxi and red telephone boxes – but is far more modern in its design and construction. The new Routemaster's main design features are its three sets of doors and two staircases, which it is hoped will ease the strain during rush hour in regards to alighting and entering the bus.

Cloud rises over diesel plan for Nissan Maxima

"We haven't reached a decision on the diesel yet, but we have to consider where we want to put our capital investments," says Larry Dominique, North American vice president for product planning.
