What ever happened to the idea of super capacitors??

Short story is that you want to be in the upper left corner of this graph to power a motor vehicle. Supercapacitors are not yet as good as lead acid or lithium ion batteries. Fuel cells are in the right spot but far too expensive using platinum or palladium as catalysts.

Super, or ultra capacitors still do not have the energy density of a battery. What they have is the ability to discharge copious amperage. I imagine a modern electric car like tesla uses both ultra capacitors and lithium ion batteries.
