  1. That is the max gross weight of the whole rig. Tractor, trailer and load

  2. What was lacking in the press release to quell the skepticism was what proportion of the GVM was payload vs tare weight. This is important to trucking companies. Quoting total mass and range is pointless without knowing how much was cargo. They could easily boasted about this but chose not to. Why not?

  3.  @vic321344  Diesel has energy density of 38.6MJ/L. The best Lithium ion batteries are 2.63 MJ/L. So energy density is nearly 15 times less for battery. Efficiencies will have to improve dramatically or the battery size will have to be much larger than diesel tank. (A lot more than 2x)
