After a final coat of paint and clear coat, Model S is transported to the assembly center on automated SmartCarts that follow magnetic tape strips on the floor. Along the way, robots use high-definition 3D cameras to accurately position the panoramic roof. The interior seats, center console, and instrument cluster are all installed as SmartCarts continue to move Model S through the assembly line. Then the drivetrain and battery modules are precision-lifted and secured. After the final exterior components, such as tires, wheels and emblems are added, your car is powered up for the first time.
Before leaving the factory, every Model S undergoes stringent quality tests on a uniquely designed final inspection platform with premium quality bamboo flooring and LED lighting. The car is inspected by Tesla associates for perfect body fit and appearance. Your Model S then enters the industry’s first all-glass water test booth, where it is sprayed by water from 360 stationary nozzles to ensure your car has perfect water tightness. Tesla’s water test booth holds 1,500 gallons of water that is purified and re-used for each test to minimize wasted resources.
As a final quality test before Model S is ready to be shipped, every car is tested on Tesla’s indoor confirmation track – North America’s first. Though most confirmation test tracks are outdoors, Tesla’s zero emissions powertrain makes an indoor test track possible.
