Listen: Upcoming Ford Focus ST to employ sound symposer

While BMW employs a digitally sanitized/perfected sound file to give M5 owners the proper sense of aggro urgency when motoring at pace, Porsche went a little more organic with its employment of a sound symposer to feed the 911's flat-six growl into the cabin of the extra-refined 991. Essentially, the sound symposer is an electrically controlled diaphragm in a tuned sound tube that brings the proper engine noises into the passenger compartment. It can be opened and closed by the car's onboard electronics to offer snarl when you want it and serenity when you don't.

SkyTran to trial maglev two-seater transport system in Israel

California-based skyTran has signed an agreement with Israel Aerospace Industries (IAI) to build a test version of its patented maglev transport network.  The 500 meter-long demonstrator will begin operation late next year, and is designed to prove the system's potential for reducing road congestion by lifting passengers above the highway, into space that's not currently utilized. The skyTran system is a network of computer-controlled, two-person vehicles that use maglev technology. Users will request one of the system's two-seater pods to the nearest available station using a smartphone app.

And it’s a sad and disappointing end for the famous Holden marque, which can trace its history back as far as 1856.
