Concept Car of the Week: GM-X Stiletto (1964)

With dreams of flying cars as the ultimate inspiration, General Motors designers in the ‘60s used every trick possible to make their creations appear as though they were floating – long, straight bodies, wheels pushed in and hidden away, large fins and lights that looked like rockets.

Exclusive First Sight: Pininfarina Sergio concept

Upon receiving the call from Pininfarina's PR man, asking if Car Design News would like to head to Torino for a preview of its latest concept car (not a hard offer to accept), we had no other information than its name – Sergio – and an abstract teaser shot of a detail.

New Audi Quattro supercar: could this be it?

Audi has released surprise pictures of one of the concept cars it will be bringing to the 2013 Frankfurt Motor Show, on its international media site.
