According to a new report coming from Autocar, Tesla is currently at work on a new Roadster that will "push the envelope beyond what anybody else is doing." The comments come from Tesla boss George Blankenship who further added that "We did an electric car with over a 200-mile range and a 0-60 mph in under four seconds. Back then, no one believed it was possible. And then we made the Model S, with 0-60 mph in 4.4 seconds and a 300-mile range." No specific date was given as to when the next Roadster will be ready, but the Model X SUV is expected sometime next year and it will be followed by a mid-size sedan in either 2015 or 2016.
