[1/5] Tesla Chief Executive Elon Musk waves near Tesla Semi electric trucks during a live-streamed unveiling in Nevada, U.S.The Semi delivery presentation ended without Musk taking questions, as he often does at Tesla events.The Semi is capable of charging at 1 megawatt and has liquid-cooling technology in the charging cable in an updated version of Tesla's Supercharger that will be made available to the Cybertruck, Musk said.The Semi uses three electric motors developed for Tesla's performance version of its Model S, with only one of them engaged at highway speed and two in reserve for when the truck needs to accelerate, a feature that makes the truck more energy-efficient, Musk said.
The presentation took place after Tesla shares closed at $194.70.
