Mullen Automotive said its subsidiary, Bollinger Motors, has achieved a key commercial EV milestone with its B4 all-electric, Class-4 low cab forward chassis truck, which received certification from the California Air Resources Board.

“The CARB certification represents an important milestone in our mission to bring a world-class electric vehicle to market,” said Bryan Chambers, Bollinger Motors’ president and chief operating officer.  “Environmental requirements are critical to meeting customer expectations and providing sale-ready vehicles. With this important accomplishment, the B4 is one step closer to electrifying vehicle fleets from coast-to-coast.”

All CARB states and locations have adopted vehicle standards Section 177 of the Clean Air Act (42 U.S.C. §7507), which requires additional approvals beyond Environmental Protection Agency regulations.

CARB certification provides a path for Bollinger Motors’ customers to qualify for additional state incentives, such as California’s HVIP project (HVIP). When combined with the B4’s $40,000 IRS rebate, HVIP can offer a rebate of up to $60,000, adding up to $100,000 in combined total savings.

Bollinger Motors will begin production of the B4 on Sept. 16, with customer deliveries to begin in October.
