Nissan Pivo

Powered by a single lithium-ion battery, Nissan’s Pivo is one of the first cars to have a spinning cockpit. This tiny car features electric sliding doors and several cameras mounted outside the cabin. Cameras located at either end of the car send a live feed to an “Around View” dashboard screen that uses the data to generate a 360-degree image.

EcoJet: The BioDiesel-Powered Supercar

Jay Leno unveils the futuristic EcoJet, a “650 hp (400 lb.-ft. of torque), bio-diesel monster supercar,” at SEMA.

The mid-engined beast, originally sketched by Leno and Ed on the back of a napkin, shares design cues with everything from jet aircraft and Formular One racecars, and even, it would appear, the nose of a Cadillac STS. The Leno-Welburn love child is powered by a Honeywell LT-101 turbine engine running in a modified Corvette Z06 hydroformed aluminum frame with aluminum and magnesium structural and chassis components

Nissan Terranaut
