Like the previously released EDrive kit, this Hymotion Prius conversion package lets you convert your stock Prius into one that can be plugged in for charging. After a 4.5-hour charge time, your Prius will be able to use more battery power over about 30-40 miles in order achieve that mileage.
The kit isn't cheap—it's $9995 with three-year warranty and installation—but it is slightly cheaper than the 2006 $10-$12k price of the EDrive (we haven't been able to find a more current price). Most of us probably wouldn't pay an extra $10k on top of the $20k or so you paid for a Prius in the first place, so you might want to sit tight for factory Plugin EVs in the next few years unless you really, really need to smell your own farts now.
