In November 2017, Elon Musk presented the new Tesla Semi promising to revolutionize the transportation industry. Up to this point electric trucks were considered something of the category of fiction, since their efficiency was very low and many automakers considered them an ineffective replacement for a conventional semi. With the lowest coefficient of drag of any semi truck Tesla is offering EV alternative to the trucking industry. In this video we look at the new Tesla Semi and calculate energy consumption and efficiency. Included in the calculations are aerodynamic drag and rolling resistance estimates.
