Greenhouse Gas Emissions
Model year 2013 and later vehicles must meet requirements as specified by EPA10, GHG14, GHG17 and GHG21 regulations. See Table and Table for additional information on what EPA and GHG regulations apply to different eCascadia model years.

GHG21 |
GHG14/17 components plus additional components including, but not limited to, transmissions, axles, predictive technologies, idle reduction technologies for vocational vehicles, and tire pressure monitoring systems. |

Table 2, Emission Regulations by Model Year
Model year 2013 and later vehicles are equipped with components that increase energy efficiency such as low-rolling resistance tires, vehicle speed limiters, and aerodynamic devices such as the hood, cab side extenders, and chassis side fairings.
It is a violation of U.S. federal law to alter components that would bring the vehicle out of compliance with certification requirements [Ref: 42 U.S.C. S7522(a) (3)]. It is the owner’s responsibility to maintain the vehicle so that it conforms to all EPA regulations.
