Elio Motors unveiled a prototype of its two-passenger, three-wheeled vehicle Wednesday, confirming the all-new vehicle will have a $6,800 base price when it goes on sale in June 2014. Paul Elio, company founder and CEO, said the vehicle is targeted at first-time or cash-strapped buyers, as well as for families who already have a family car and are seeking something inexpensive for daily commuting.

Autoweek joins Porsche's engineering team for the very first test of the car that is already causing headaches in Maranello and Sant'Agata. For all of its intense promise and awesome potential, the very first running prototype of the upcoming Porsche 918 Spyder looks suspiciously like a refugee from a shadowy postapocalyptic movie set as it glides silently into view across the vast expanse of bitumen at the Nardo test track in southern Italy.

Unlike most other touchscreens, Krenn's interface isn't organized into menus and small, hard-to-hit buttons, but instead makes use of multi-touch gestures, reducing the accuracy and attention needed to operate key functions.
