The Model X is a variance on the Model S platform. So, it a crossover SUV. It's intended to be cooler than any other SUV in its aspiration, but actually have functionality that exceeds that of a minivan. This is a tough goal to achieve, but I think we have a better shot at doing that. That's why we we're raving it. Pricing would comparable to that of the Model S, and so this is not our third-generation last production vehicle. That vehicle is still several years away. The Model X is really just a way of generating potentially twice as much volume in the premium vehicle segment offering a crossover SUV in addition to sedan, and we are looking to unveil the design prototype about at the end of this year.
