In what way is it similar? The electric motor has the wide range of speeds available, and the gearing is completely fixed.
Completely fixed vs continuously variable seem about as far apart as it gets in my mind.
What I meant was that in both cases there is essentially one gear, but I see you're point. CVT can be thought of as infinitely many gear ratios and the Leaf's is only one. I updated the article, so hopefully it's more clear.
