The Polestar 5 will be cut from a different cloth than its predecessors when it launches at the end of 2024. Polestar announced on Tuesday that its upcoming electric performance sedan will ride atop an entirely new, lightweight bonded aluminum platform rather, than the welded design used by the 1 and 2.

Because welding aluminum generally halves its yield strength, you end up having to use double the amount of material to achieve the same performance — which defeats the whole purpose of using the lightweight metal in the first place. Bonding aluminum parts together (ie affixing them with screws and adhesive), on the other hand, cuts down on the materials needed but at the cost of extended production times.
