Is the Tesla Roadster an Electric Elise?

What can $40 million in venture capital funding buy a prospective builder of upscale electric sports cars? According to one reader, who claims to have an inside track into the Tesla Roadster project, it's a straightforward formula:

1. Start with one Lotus Elise
2. In place of Toyota 4 cylinder, substitute a big 'ol stack of Li-on batteries and an electric motor
3. Hit 60 in 4 seconds

Simple, no?
