Of course, the Model S wasn't Tesla's first electric vehicle. That honor instead goes to the Tesla Roadster, and you could make the argument that makes it more important than the Model S, but if you're really honest with yourself, you know that's not true. It may have been cool and futuristic, but it was also a car legacy automakers could mostly ignore. You could also argue the Bugatti Veyron deserves that title more than the Model S, but again, I think you have to admit the Model S was more important. I am, however, open to hearing arguments defending the second-generation Toyota Prius.
