Yesterday, Elon Musk appeared at his first Tesla unveiling since he took the helm at Twitter. At a Tesla plant in Nevada, the billionaire announced that after five long years, Tesla’s first heavy-duty Semi had been delivered to PepsiCo.

The Semi, Tesla announced, would go into production in 2023 and feature an updated version of Tesla’s Supercharger, which uses liquid-cooling technology in its charging cable and is capable of charging the large electric vehicle at 1 megawatt.
