Kode 0 (by Ken Okunaya). 

Before we talk about the car, we first have to talk about the man behind the car: Ken Okuyama. If that name sounds familiar, Okuyma is a career automotive design pro who spent much of his career at Pininfarina. He's credited in helping create vehicles like the original Acura NSX, Ferrari 599 GTB, Ferrari Enzo, Maserati Birdcage 75th Concept, and even the fourth-generation Chevrolet Camaro. Yes, that Camaro. But in 2006, Ken Okuyama left Pininfarina. And after a quick stint starting his own eyewear collection (dubbed Ken Okuyama Eyes collection), he created his first self-titled concept car: the K.O 7 Spider. He debuted the slinky, open-top two-seater in Geneva in 2008, kickstarting a lineage of impressive concepts and one-offs, including the one pictured here.

The fixed-roof successor to the equally stunning Kode 57 Enji uses "dream car proportions" from classics like the the Lancia Stratos Zero in its design. Okuyama implemented a "one motion" technique to create the Kode0's svelte profile. But aggressive details like the edgy front splitter, sharp LED headlights, triangular-shaped exhaust, and 21-inch wheels embody a stark contrast to the otherwise streamlined silhouette.

Hiding under that sleek contour is a 6.5-liter V12 good for 690 horsepower (515 kilowatts) and 507 pound-feet (690 Newton-meters) of torque. With it, the Kode0 sprints to 62 miles per hour (0-100 kilometers per hour) in just 2.9 seconds. The Kode 0 also weighs in at just 3,417 pounds (1,550 kilograms), making it much lighter than the vehicle on which it's based (4,085 pounds / 1,852 kilograms).
