New Vehicle and Engine Certification: Executive Orders for MY2021 Medium-Duty and Heavy-Duty Engines

The New Vehicle and Engine Certification Program is responsible for the certification of new engines, vehicles, powertrains, aerodynamic devices and other new certifications. Vehicles and engines may be sold and otherwise produced in California only if approved by Executive Order (EO) after review by CARB. Executive Orders are issued for on-road and off-road categories.

Scanned copies of issued Executive Orders may be requested via email.

The following Executive Orders granted to the listed manufacturers of on-road medium-duty and heavy-duty engines have been issued during the 2021 model year, as of June 5, 2024.
