The Tesla Model X is an all-electric crossover that seats 7 adults and features "falcon-wing" rear doors, which require little clearance on each side of the vehicle. The Model X is based on the Model S platform, and shares about 60% of the its parts with the sedan. Like the Model S, the Model X will have three battery pack options. The Model X is about 10% heavier than the Model S, and will consequently have about 10% less range than the Model S. Like the Model S, the Model X has two trunks: one in the rear and one in the front (also called the "frunk"), giving the Model X an immense amount of cargo space for an SUV. The Model X will be available in a 2- or 4-wheel drive model. Tesla plans to release the Model X in late 2013 and be in full scale production in early 2014.
