FREMONT, Calif. -- Amid great fanfare and expectations, Tesla Motors unveiled the Model X, its all-electric SUV, at an event Tuesday night at its Bay Area factory.

The Model X is the second car available for sale from the electric automaker, which introduced the Model S sedan three years ago. The high-speed Roadster, its first car, was discontinued in 2012.

The all-wheel-drive, seven-passenger X could help Tesla crack into the SUV market. The vehicles experienced a surge in sales over the past year and are popular with female drivers.

Shoppers can put down $5,000 on Tesla's website to reserve an X when they start rolling out. The base price actually runs up to $132,000 for the Signature Series, which includes add-ons like an autopilot mode and heated steering wheel and seats.

A less expensive version, the $35,000 Model 3 sedan, is expected to come out in 2017.

The X boasts a lot of power. It goes from o to 60 mph in 3.2 seconds , and has a range of about 250 miles before the battery needs a recharge.

Plus, it's stylish. A new feature, the "falcon wing doors," swoop out and up. (It's easy to picture "Silicon Valley" character Russ Hanneman approving of the design.) There are three rows of seats, but the second row holds just two passengers.

The X features a windshield that extends above the driver's head, offering panoramic views and the feel of a helicopter cockpit, Musk said.

Most importantly, though, Musk said that the Model X is safe.

"We've made the safest SUV ever," he said. Sensors can automatically apply the brakes or steer away from cars and dangerous objects, he said during the debut, which was webcast from Tesla's Fremont, California, factory. "There's really nothing that's more important" than safety.
