Based on Natural Resources Canada’s (NRCan) approved guidelines. Refer to NRCan’s Fuel Consumption Guide available at https://fcr-ccc.nrcan-rncan.gc.ca/en for more information. Full battery charge and ideal conditions are required. Figures will vary based, amongst others and non-exclusively, on driving and charging habits, speed, accessory use, weather and temperature, battery age, vehicle condition, road condition and other factors. In sub ideal conditions, figures may worsen by more than 50%. Battery capacity decreases with time and use which will further reduce range. See the owner’s manual or NRCan’s Fuel Consumption Guide for details.
What's a PZEV?
The Subaru PZEV (Partial Zero Emission Vehicle) is the affordable, no-compromise, eco-friendly alternative. Although the Subaru PZEV runs on regular unleaded fuel, it offers significant smog-reducing environmental benefits and delivers equal performance compared to non-PZEV cars or SUVs, including hybrids, diesels and alternative fuel vehicles.
A PZEV is classified as the cleanest-running gasoline-powered car on the market and was developed to meet the air quality standards of California, the most stringent in North America. A PZEV must meet the Super Ultra Low Emissions Vehicle (SULEV) tailpipe standard and have zero evaporative emissions.
Rating Scales by Model Year (MY)
California Air Resource Board
Emission standards are for the major pollutants in vehicle exhaust:
- NMOG, NMHC, or THC—types of carbon-containing compounds, including hydrocarbons
- NOx—Oxides of Nitrogen, which combine with hydrocarbons to create smog
- PM—Particulate Matter, tiny particles of solid matter that lodge in the lungs and deposit on buildings
- CO—Carbon Monoxide, a colorless, odorless, poisonous gas
- HCHO—Formaldehyde, a lung irritant and carcinogen
* Vehicle must also be certified to CA PZEV or SULEV20 standard

Advantages
Subaru PZEVs allow drivers to reduce their impact on the environment while sacrificing nothing by delivering a win-win combination of advantages:
How does it work
With Subaru PZEV vehicles, the remarkable reduction of smog-forming emissions is achieved through modifications in four key areas:
Catalytic converter
A larger and finer mesh of catalyst-lined passageways within a Subaru PZEV catalytic converter greatly contributes to its ability to reduce emissions. Along the entire length of the mesh are precious metals (catalysts) whose role is to change the molecular structure of the offensive emissions that try to pass through. In fact, the contact area is almost twice that of a traditional catalytic converter, producing a much more effective conversion of pollutants.
Fuel injectors
The fuel injectors on Subaru PZEV vehicles close tighter than conventional injectors to prevent evaporative emissions from fuel leakage into the intake manifold.
Dual-filtration air-intake system
In a conventional vehicle, unburned gas fumes can escape through the engine’s air intake once the engine is shut off. To prevent this, Subaru PZEVs are equipped with a charcoal canister in the air intake that absorbs these evaporative hydrocarbon emissions.
Engine Control Module (ECM)
Vehicle emissions are worst in cold start conditions. Subaru addresses this problem by altering the programming in the Engine Control Module to delay ignition timing, making the exhaust gasses hotter, which helps the catalytic converter heat up sooner, reducing emissions.
