The Wrightspeed X1
Faster than anything else on the road with the possible exception of the Bugatti Veyron (for which you need a personal Saudi Arabian oil field just to keep the tank full) the Wrightspeed X1 is exactly what we need to see a lot more of, electric cars that take full advantage of the superiority of the electric motor over the internal combustion engine to make Ferraris, Porsches and anything else on 4 wheels look like a lumbering, antiquated grease-trap.
Based on the Ariel Atom with a drive-train from AC Propulsion (the Tesla Roadster also uses AC Propulsion) and a battery system from A123 Systems the Wrightspeed X1 couldn’t have better credentials. The car features a standing 1/4 mile time of 11.5 seconds, enough to make dedicated drag-racers look somewhat inept and can leap from 0-60mph in 3.0 seconds (or 117 feet). The detractors may point out that the car has no roof. Or doors. Or body panels. But that is missing the point. This is a car designed to showcase electric vehicle technology in a light, nimble package.
Wrightspeed are working on a full production car and according to company founder Ian Wright “… the production car will be quite different, since it will meet safety standards, which the prototype does not. It will, however, be at least as quick as the prototype.” Stay tuned for updates, we expect to see a lot from this little company.
