Tesla plans to manufacture a car that will cost $25 000 in about three years’ time, fulfilling an elusive long-term objective to sell a cheap mass-market electric vehicle, CEO Elon Musk said Tuesday.

“This has always been our dream from the very beginning,” Musk said at an event showcasing Tesla’s technology. “In about three years from now, we are confident we can make a compelling $25,000 electric vehicle that is also fully autonomous.”

Tesla announced a series of vertical integration improvements, from making its own battery cells to owning rights to a lithium mine in Nevada, that will allow it to cut costs and offer cheaper cars as soon as 2023.
