I’ve never seen an ICE car need two engines to drive all four wheels. Why do EVs need 2 motors? Wouldn’t a transmission be cheaper than another motor?

    In an ICE car with AWD, the power can be transmitted through the driveshaft. In most EVs, the battery pack sits where the driveshaft would go. This would not apply in all cases, but in most.

      Battery cells are small, so you can design the pack with empty space for the driveshaft. Probably not a huge point in doing that.

        Individual cells are small but in total you need every bit of space that you can possibly spare.

      Yes, a drive shaft and transfer cases/gear boxes hugely complicate what can be a very simple EV platform. Also adds maintenance.
