Partial Zero Emission Vehicles

I just saw that Honda is advertising a "Partial Zero Emission Vehicle," which sounds really cool. No one else is marketing a Zero Emission Vehicle right now. This is "Partial Zero," but as every 3rd grader knows, a part of zero is still zero. Try it: 1/10 * 0 = ??

I suppose it's possible that they intended to hyphenate, indicating that their car is partially a Zero-Emission-Vehicle. This makes me wonder, which part? No emissions on the left side? Or from the front? Of course, nearly all cars in good repair could be called zero emission from the front, all the emissions come out the back. So maybe the zero-emission part is just the passenger cabin. Of course, this would depend on operator skill. For instance, too much chili could compromise the zero-emission nature of the car.

Well, I'll just be mystified for the moment. In the meantime, I can't wait until some car maker remembers the actual zero emission vehicle they made in the 1990s, and decides to market it again.
