Advanced Technology Partial Zero-Emission Vehicle (AT-PZEV)
To achieve Advanced Technology Partial Zero-Emission Vehicle (AT-PZEV)[1] status, a vehicle must meet Super-Ultra-Low-Emission Vehicle (SULEV)[2] tailpipe emission standards, carry a 15-year/150,000-mile warranty on emissions equipment, have zero evaporative emissions and include advanced technology components.

[1] AT-PZEV (Advanced Technology Partial Zero-Emission Vehicle) models as certified by California Air Resources Board (CARB) and states that have adopted California Zero-Emission Vehicle regulations.

[2] SULEV (Super-Ultra-Low-Emission Vehicle) rated by the California Air Resources Board (CARB).
Compressed Natural Gas (CNG)
The compressed natural-gas (CNG) fuel tank is almost as impressive as the engine. The tank is lightweight, strong and built for safety. And for extra peace of mind, we've equipped the tank with an in-tank solenoid valve that will cut off the flow of gas if the system is compromised, or when the engine is turned off.
