Tesla Test Drive at New Dealership in Santa Monica
Tesla Motors released a white paper in October 2006 comparing well-to-wheel efficiency (well-to-wheel refers to the entire life of the fuel - from the point when the raw fuel is abstracted from its source [i.e. the well] to the point it turns into your vehicle's motion [i.e. the wheel]; well-to-wheel allows for a standard metric to compare different fuel types), well-to-wheel carbon dioxide emissions, and 0 to 60 miles per hour acceleration for a variety of technologies and example cars. In each case, the Tesla came in first (the Prius came in second for well-to-wheel efficiency and emissions but came in 6th in terms of acceleration).

Originally, the Tesla Roadster was to be delivered during the 2007 summer. Then the release date was pushed to October 2007. But in September, the interim CEO Michael Marks sent a letter to customers announcing another delay. At this point, 50 Roadsters will ship during the first quarter of 2008 and another 600 will ship during the rest of the 2008 model year. According to Darryl Siry, Tesla's VP of Sales, Marketing and Service, the primary cause of the delay has been issues with durability and reliability of the transmission (he has also said that the initial rumors of issues with the lithium-iron batteries are entirely untrue).
