Porsche 904

Imagine a 1.2-liter Ducati L-twin, screaming its desmodromic song just inches behind your head—spinning 11,000 rpm, pushing something like 200 horsepower, and propelling your beautiful little carbon-fiber Porsche, which weighs a hair under a ton, through space. It's a minimalist's fantasy, the notion of a sports car reliant on a lack of weight rather than an abundance of horsepower to achieve remarkable performance. That's a large part of the spirit of Porsche, and it was distilled into the 2013 904 Living Legend Concept. The car was light, lithe, and striking.
