“PZEV” – WHAT DOES IT MEAN, AND HOW DOES IT APPLY TO SUBARU VEHICLES?
In the last issue of Drive, the article Controlling Emissions – Part One stated “... that some Subaru models have available Partial Zero Emission Vehicle (PZEV) engines.” In Part Two, we take a closer look at Subaru PZEV models.
California vehicle standards have led the way in requiring low emissions by vehicles. Set by the California Air Resources Board (CARB), these stringent standards have been adopted by several other states, including Connecticut, Maine, Massachusetts, New Jersey, New York, Oregon, Pennsylvania, Rhode Island, Vermont, and Washington. Automakers produce vehicles that meet both these requirements and ones set by the U.S. Environmental Protection Agency (EPA).
CARB defined the PZEV classification. A PZEV vehicle meets Super Ultra Low Emission Vehicle (SULEV) exhaust emission standards and zero evaporative emissions standards. Vehicles meeting these standards are considered the cleanest gasoline-powered vehicles. In addition, the PZEV classification includes a 15-year/150,000-mile (whichever comes first) emission performance and defect warranty, including the On-Board Diagnostic (OBD II) vehicle system, depending on the state in which the vehicle is sold.
At Subaru, protecting the environment is just as important as protecting our passengers. That’s why we build fuel-efficient vehicles in ecologically minded plants. Subaru of America, Inc. offers Legacy, Outback, and Forester 2.5L naturally aspirated (non-turbocharged) vehicles that achieve a PZEV rating by the California Air Resources Board. We plan to enhance this product offering in the future. The EPA endorses all Subaru PZEV vehicles as SmartWay®1 certified and promotes them in their Green Vehicle Guide.2
