If anything the taller cylinder will use more aluminum for the same volume, so they're kinda shooting themselves in the foot here with aluminum and steel tariffs, lol
Semms pretty clear the only reason for this was to change the price without as many people noticing.
Regular cans are somewhat inefficient shapes as well, shorter and fatter would be more economical, but less ergonomical and for once that won out, for a while anyway. Now we get designed by marketing instead.
Yeah, there's an awesome video on aluminum drink cans from TheEngineerGuy on YouTube. The ideal shape for holding pressure with minimal material is a sphere, but there's 2 problems with that: They roll, and can't be packed as efficiently as cylinders.
The tall cans have more surface area. It does mean slightly more materials (but not that much because the can thickness is not uniform), but also more visibility in vending machines and stores. It's a purely marketing decision.
