I think to my older iphones on the ski hill - they'd power themselves off in the cold but still have like 50% battery when I powered them on again indoors...

Most of the range loss isn't really that the battery is cold per se, though that certainly does decrease some efficiency, it's that both the battery and cabin need heat to function. With an ice vehicle, there's excess heat from the engine anyways so there's no loss. For electric vehicles they need to use power to heat them up so there's less electricity left to send to the wheels
