Tesla Roadster: 135 mpg, 250 mile range, 0 to 60 in 4 seconds (updated)

Independent Silicon Valley-based automaker Tesla has unveiled the Tesla Roadster -- an all-electric car capable of accelerating to 60 mph in just four seconds, while offering equivalent mileage of 135 mpg, and a 250 mile range. The high-performance roadster is capable of hanging with a Ferrari F430, Porsche Carrera S, or BMW M5. The car has a more-than-sufficient top speed of 130 mph, the automaker said. Funding came from several big names in the technology world, including Google founders Larry Page and Sergey Brin. The car is expected to cost between $85,000 and $120,000. Deliveries of the Tesla Roadster in the United States are expected to begin next summer. Gallery after the jump...
