Anyone else want to add their experiences with their electric (or PHEV) ?
Well, since you included PHEV (which I guess is similar to a PZEV) I have a Honda Civic Hybrid. It has a different engine than regular Civics, with variable intake valve timing and the ability to cut off several cylinders. So, it has no throttle, but reduces engine output by allowing less fuel/air charge into the cylinders. This takes several seconds to do, so would be unnerving without the hybrid motor/generator. With the hybrid system, any time you move the gas pedal, it immediately uses the hybrid motor/battery to supply or extract the required energy until the valve timing is adjusted.
Rather complex stuff, but it seems to work really well, and reliably. They also have a chain-drive continuously variable transmission, with a wet-pack clutch similar to what is on a motorcycle.
Anyway, it all works quite well, and when ** I ALONE ** drive it, I can get over 50 MPG using US gasohol. When my family drives it, they can get the mileage down into the 40's right away. (ugh) The only problem I've had with it is the battery pack blew at 68,000 miles, and is getting ready to do it again. Whoever thought you could put 120 Ni-MH D-cells in series with no cell balancing and hit it will 100 A charge and discharge cycles for years should have been fired (and maybe put in the nut house). It is totally amazing that the battery can take that abuse for several years before slowly going bad.
So, I like it, and may get another hybrid. I'm wondering if the Toyota Prius Prime (plug-in hybrid) might be my next car.
