2012 Subaru Impreza: Know Your PZEVs and SULEVs

July 02, 2012

In a comment to my earlier post on our Subaru Impreza, stovt001 wondered if the majority of mainstream cars are rated as Partial Zero Emission Vehicles, or PZEVs, in the parlance of the California Air Resources Board.

Good question. I did a little digging into the state's DriveClean Web site, and the answer is no: Most cars are not PZEVs. Here's a link to the 2012 PZEVs. There's plenty of them, but the list doesn't reflect the majority of mainstream cars.

To get the PZEV designation, a car has to rate a 9 on the state's smog score. In addition to our Impreza, our Mazda 3 also qualifies as a PZEV. Our Prius C, however, falls into another category: It's a "Super Ultra Low Emission Vehicle" with an emissions rating within California's LEV 1 and LEV 2 exhaust emission standards.

Here's a glossary of California clean-car terms, just in case you haven't had enough on the subject.
