It's a bit misleading, yeah. The new cell has 5x the volume of the old one, so naturally it holds 5x more energy. But they can't just put the same number of these new, bigger cells into the car. The 16% increase in range is a combination of the new cells and the fact that they've made the battery pack itself a structural part of the car, which makes it lighter and more efficient.

All depends on the bms (battery management system) and how efficient the car is. Just because it can hold more energy, doesn't mean all the factors stay the same (such as weight, efficiency, etc)

The 5x more energy thing is a little confusing, but it's about the individual cells being bigger and holding a lot more. The 16% range boost is the actual result for the entire car. It comes from the new cell design, the improvements in the anode and cathode materials, and the way the whole battery pack is integrated into the car's chassis. They're making the whole car lighter and more efficient, so the range goes up a bit more than just from the battery itself.

Okay, this is a little bit of a misunderstanding. When Tesla said "5 times more energy," they were talking about the individual battery cells, not the whole battery pack. The new cells are a lot bigger than the old ones, so they can hold a lot more energy on their own. But when you put them all together in the car's battery pack, you can't just multiply that 5x number. The new design allows them to make the whole battery pack more efficient, pack more cells in, and reduce the overall weight and number of parts, which is where the 16% range increase comes from. It's not a direct 1-to-1 correlation, because the efficiency of the car itself and the way the pack is built also makes a big difference.
