A new battery system and an aerodynamically optimized cab give Scania’s electric big rig an edge over the Tesla Semi.

That’s Fuel Energy Content =7490kWh with a Usable Electricity =2247kWh

Please people, stop doing this sophomoric math.55% of the energy in Diesel is wasted as heat and noise.

Stop getting science from YouTube.

    Isn't the rate quoted actually less efficient than the ~45% efficiency of a diesel engine? Seems like they went for 30% efficiency.

    The noise is irrelevant unlike the waste heat, too. It can't be that much energy given that tire noise takes over at any real speed (tire noise actually being worse for EVs since the batteries are heavier).

    But that's nitpicking at this point. As long as you can steal electricity from somewhere, these trucks are going to be hella cheaper to run than diesels that require a ton of maintenance.

    Good feckin point.

    I don't suppose you've got the ratio between heat and noise?
