Tesla CEO Elon Musk delivered the first heavy-duty Tesla Semi trucks to PepsiCo on Thursday. The trucks were unveiled in concept in 2017 and were to go into production in 2019, but the plans got delayed. Semi can accelerate 0-60 mph in 20 seconds and has a battery range of up to 805 kilometres. PepsiCo ordered 100 Semis in 2017.
