An anonymous reader writes with news that Tesla has officially unveiled its Model X SUV. It's their third vehicle, after the Roadster and Model S. Its 90kWh battery provides 250 miles of range, and the vehicle can go from zero to 60 mph in 3.2 seconds. According to Reuters, the high-end versions of the Model X will cost between $132,000 and $144,000, while the base model's pricing is not yet known. The vehicle's doors open upward, and it can have seating for either six or seven passengers, depending on layout. The back row of seats can fold down when not in use. The Model X has automatic emergency braking, a 5,000 pound towing capacity, and a so-called "bioweapon defense mode" for its air circulation system that keeps positive pressure within the cabin.
