Actually, PZEV makes sense if you know what it refers to.
PZEV's have zero evaporative emissions, and "super ultra low" tailpipe emissions
That's what the "partially zero" means - they have zero evaporative emissions.
- schiffern 8y ago>That's what the "partially zero" means - they have zero evaporative emissions. Except it doesn't mean "partial zero." Instead, it refers to a "partial ZEV" (ie a partial vehicle). The argument is that having a greater number of lower-emission vehicles[1] on the road has the same effect on air pollution as having a smaller number of zero-emission vehicles. So if those vehicles count as a partial ZEVs (for the purposes of the CARB ZEV Mandate), the same overall policy effect would be achieved. [1] as you point out, legally they defined this as meeting the EPA SULEV emission requirements, plus having zero evaporative emissions
- calcifer 8y agoThat's just marketing bullshit. Like partially zero calorie cake. You know, it has zero calories, except for the parts of it that doesn't.
- cowsandmilk 8y agoIt had less to do with marketing and more to do with negotiations with California's Air Resources Board. The category was created as a stepping stone towards mandated zero emission vehicles.
- DannyBee 8y agoErr, no. It's quite literally not. Your example is about measuring one thing. The standard does not measure one thing. It would be like calling it "partially zero cake" because it has zero sugar but some fat. Also note that ZEV's do not take into account any of the emissions related to production of the fuel/electricity they use - that is outside the standard. So they may have more net emissions, they may have less.
