Our editors have compiled a list of seven high-tech cars you can’t buy, or at least anytime soon. If we happened to miss any, please leave us a comment. “Continue reading” for the entire list.

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


Renault Nepta

Renault’s sleek new Nepta concept is powered by a bi-turbo, 3.5L V6 engine that generates an impressive 420hp — boosting it from 0-62 in just 4.9-seconds.

It also features LED headlights and taillights, carbon bodywork, anti-roll bars, digital and analog instruments, Michelin’s latest prototype tires, advanced air turbulence deflectors, and DVD screens

Peugeot 908 RC

The stunning Peugeot 908 RC is powered by a turbocharged V12 HDi DPFS (diesel particulate filter system) diesel engine that generates 691hp and 885+ lb-ft torque, mated to a 6-speed electronically controlled sequential gearbox. .

With a 100° V angle architecture, the engine’s centre of gravity is as low as possible. Two particulate filters are located at the end of each exhaust system ensuring the car’s environmentally-friendly credentials



Powered by a twin-turbo, 400 bhp BioPower V6 engine, this concept is all about eye candy, with a cockpit canopy (replaces doors and windscreen pillars) that gives the driver full 180-degree views. The ultralight carbon fiber chassis, lightweight powertrain, and all-wheel drive suspension help the Aero-X rocket from 0-62 mph in just 4.9 seconds (computer simulated trials). [Source 12]

Nissan Terranaut

Designed for “scientists, geologists, archaeologists or adventurers”, Nissan’s 4×4 Terranaut features a “spherical laboratory” that is accessed from a 360 degree swiveling seat. Unfortunately, all these workstations leave room for only one passenger side door.[Source]
