How looks the factory where Tesla is building its new Model X?

Over the past decade, Tesla has grown from an ambitious upstart into a global leader in electric vehicles. Its Model S sedan has set a performance benchmark for competitors looking to enter the segment, and today it will sell its first Model X sports utility vehicle.

This week, Business Insider made our way over to Silicon Valley and took a tour of the Tesla Factory. Tonight we'll be at the delivery of the first Model X, so check back for coverage. Here's the factory:
