A Dutch Tesla forum declares that a Euro-authority has approved nomenclature for a new class of 100 kWh Teslas. Could this be the fruit of Tesla’s contract with mad scientist Jeff Dahn? When will Tesla officially unveil the upgrade? When will it hit the streets? Will it boost acceleration or range, or both? Can Tesla be caught by the tail by rival automakers, or is it pulling farther ahead with every iteration? How much more juice can Tesla extract from the battery array that fits in the S/X platform? Will vehicle size ultimately corral the potential? Is charging speed the next frontier?
