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?

    Why do EVs need 2 motors? Wouldn’t a transmission be cheaper than another motor?

    The EVs don’t need 2 motors for AWD, but as opposed to what you say - a second motor is lighter, cheaper, simpler and much more efficient than adding a long shaft, transfer case and two extra differentials. On top of all that you also get the performance benefits of ability to independently govern the amount of power going to each axle.
