Tesla's Roadster has done a lot to add a dash of sport to the stereotypical image of the electric vehicle as dreamy, dowdy, dutiful, or dull. But Tesla's business model and retail potential have yet to be proven--as does its upcoming product line. But as the company prepares for its initial public offering of stock (IPO) CEO Elon Musk has revealed what it plans to do and how it plans to do it, including sketches of its next three vehicles.

The three vehicles include the previously announced family sedan, a crossover, and a van-like utility vehicle. Tesla didn't release any target dates for production of the cars, but in his presentation Musk describes Tesla as a "friggin' technology velociraptor" and says the cars to come will be "frickin' badass."

As Tesla's technology and product volume grows, it is projecting a reduction in the cost to produce the batteries that power its cars, with the Roadster Sport already demonstrating a 31 percent savings over the original Roadster, and the Model S planned to save 56 percent in terms of dollars per kilowatt-hour.

In addition to the new vehicle plans, Tesla is selling itself to potential investors as the leader in the electric vehicle market. Musk claims to have the best motor, battery, and control electronics technology. While that may be up for debate, the company's powertrain agreements with Daimler and Freightliner do show industry confidence in Tesla's hardware, as does Toyota's investment in the company. Whether that confidence is justified remains to be seen, however.

Also included in the presentation at Retail Roadshow are several videos pitching the Model S and explaining how Tesla has built its team, processes and technologies. For the full presentation, hit up the link below.
