High Heavy Load Consumption
Tesla may tease their fans with the Cybertruck, a rig they designed to be the first fully-electric commercial vehicle, but the truth is that is far from reality. No matter how strong or big your battery pack is, the energy consumption under a heavy load is excessive (via Automotive IQ).
Regardless of the big torque that electric engines produce, when you put a lot of weight on them, they drain the battery quickly. Yes, the internal combustion engine also uses more fuel under a load, but not nearly as much as the electric.
