Tesla Model X crossover to debut February 9

We already know that the all-electric Model X crossover will ride on the Model S's platform, but soon we'll know what it looks like, too.

Tesla CEO Elon Musk has confirmed that a prototype of the all-electric Model X crossover will be revealed on February 9 at the automaker's design studio in California.

The Model X, which was originally slated to be shown at the North American International Auto Show, will ride on the Model S sedan's aluminum-intensive platform. It is expected to power all four wheels, possibly by utilizing the Model S's electric drivetrain at the rear wheels while adding one to two electric motors up front to motivate the rear wheels.

Besides its pure electric powertrain, the Model X will seek to stand out from the crossover crowd with a capacious interior - in a May 2011 filing with the U.S. Securities and Exchange Commission, Tesla said that it was "designing the Model X to incorporate the functionality of a minivan with the consumer appeal of a sports-utility vehicle."

The Model X will likely arrive in showrooms in late 2013 with a price similar to that of the Model S, which will go for $49,900 after federal tax credits.
