A 40 mpg plug-in hybrid mid-sized pickup (Toyota Tacoma, for instance) would be the holy-grail of pickup world. Full-on EVs are currently best suited to smaller passenger cars, and people forget that most pickups require much more torque and hauling capability. Thus the full EV pickups have a range/torque trade-off, and unless batteries improve substantially, this problem will remain. One zero emission pickup alternative (that Toyota is developing) is the hydrogen fuel-cell pickup, which does satisfy the torque/range requirement (but is currently quite expensive). I was in the Electric Auto Association beginning in the 80s, and bought my first EV in '89. As many point out, EVs are not quite zero emission either (when you consider the electricity source and manufacture of components). My conclusion at the time was that an EV was comparable to an 80-100 mpg gas engine. Someday energy will come entirely from renewables and batteries will be much better, but hybrids (especially in pickups) are a great transition device for now.
