Enter Toyota: A leaked document reveals the automaker told its dealership network that the lithium and other rare materials required to build an EV could also be enough for six plug-in hybrids. Or, it could make 90 hybrids. What’s more, swapping 90 internal combustion cars for hybrids is much better for the environment than building one full EV. Much, much better. Toyota: “The overall carbon reduction of those 90 hybrids over their lifetimes is 37 times as much as as single battery EV.”
