REE Automotive, a provider of full by-wire electric trucks and platforms, has received two certifications from the California Air Resources Board on the Class 4 P7-C chassis cab. The two certifications include Phase 2 Greenhouse Gas (GHG) covering the complete vehicle and the new Zero Emission Powertrain (ZEP) certification.
The company said in addition to California, several other states are expected to adopt the Phase 2 GHG and ZEP requirements in the coming years. REE had already announced it had received Federal Motor Vehicle Safety Standards (FMVSS) and Environmental Protection Agency (EPA) certifications.
What CARB Certification Means for REE
CARB certification is a requirement for eligibility for several state incentives, which combined with federal incentives can total more than $100,000 per vehicle depending on customer location. California and several other states have indicated plans to adopt the Advanced Clean Truck Regulation, a manufacturer's sales requirement to sell growing percentages of electric trucks that also requires ZEP certification.
“Being CARB certified unlocks many doors for us and for our customers as we can now sell in California,” said Daniel Barel, CEO and co-founder of REE Automotive. “This is an important milestone since now Powered by REE vehicles can receive more than $100,000 incentive funding which makes it even easier for fleets to electrify. We believe that this cost savings, combined with our REEcorner and x-by-wire technology’s ability to lower total cost of ownership, will boost even further the strong demand we see for our P7 lineup.”
REE said the P7-C has already achieved FMVSS and EPA certification, making it the first U.S. FMVSS-certified fully by-wire vehicle.
How the REE P7-C Works
Vehicles powered by REE are equipped with the REEcorner, which packs critical vehicle components (steering, braking, suspension, powertrain, and control) into a single compact module positioned between the chassis and the wheel.
REE’s proprietary by-wire technology for drive, steer, and brake control eliminates the need for mechanical connection. Using four iden6cal REEcorners enabled REE to make what the company calls the industry’s flattest EV platforms with more room for passengers, cargo, and batteries.
