Tesla CEO Elon Musk made a stunning announcement, confirming the company will begin phasing out its two most iconic electric vehicles, the Model S and Model X, this year, as reported by NBC News. Musk was explicit about the timeline, stating, “We expect to wind down S and X production next quarter and basically stop production.”This really signals the end of an era. The Model S, introduced in 2012, and the Model X, which followed in 2015, were the vehicles that proved electric mobility could be mainstream. The Model X, a crossover SUV, followed a few years later. Tesla will end production of its Model S sedan and Model X SUV and convert assembly lines at its Fremont factory to manufacture Optimus humanoid robots, CEO Elon Musk said.
