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.

Enthusiast 3D prints an Aston Martin DB4

New Zealand enthusiast Ivan Sentch is in the process of 3D printing a 1961 Aston Martin DB4. Engadget reports that he bought a $499 Solidoodle 3D printer and has been working on this project since December 2012. Using a Nissan Skyline as a donor car, he'll make a fiberglass mold of the print and hopefully transform this thing into a drivable, street-legal car for a fraction of the cost of an authentic DB4.
