Nightline: Tesla EV Roadster

Powered by an 3-phase, 4-pole AC electric motor, the Tesla EV Roadster has 248 hp, is capable of accelerating from zero to 60 mph in about 4 seconds and can travel 250 miles per charge at a cost of about two cents per mile (small consolation given the $100,000 sticker price). The starting point is a high performance sports car (now in production), but the company’s long term vision is to build cars of all kinds, including low-cost family vehicles. More at their website.
