Mullen Automotive, Inc., announced that its subsidiary, Bollinger Motors, has achieved a commercial EV milestone with its B4 all-electric, Class 4 low cab forward chassis truck, receiving certification from the California Air Resources Board (CARB).
The CARB certification is a requirement to sell vehicles in the CARB-compliant states of California, Colorado, Connecticut, Delaware, Maine, Maryland, Massachusetts, New Jersey, New Mexico, New York, Oregon, Pennsylvania, Rhode Island, Vermont and the District of Columbia.
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.
Gearing up for Production After B4 Certification
CARB certification provides Bollinger Motors' customers a path to qualify for additional state incentives, such as California's HVIP project. 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 savings.
Bollinger Motors will begin production of the B4 on Sept. 16, 2024, with customer deliveries to begin in October.
"The CARB certification represents an important milestone in our mission to bring a world-class electric vehicle to market," Bryan Chambers, Bollinger Motors' president and chief operating officer, said.
"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," Chambers continued.
The CARB certification is among a long list of Bollinger Motors' milestones in recent months, including:
Receiving the Certificate of Conformity from the Environmental Protection Agency.
Providing full warranty coverage of the B4 chassis cab.
A 145-vehicle sale to Momentum Group.
A 70-vehicle sale to Doering Fleet Management.
A 50-vehicle sale to EnviroCharge.
The addition of TEC Equipment, Affinity Truck Center, Nacarato Truck Centers, Nuss Truck & Equipment, and LaFontaine Automotive Group as dealers and service centers.
Adding Our Next Energy in Novi, Michigan, to supply battery packs.
Teaming up with Syncron as its warranty administration partner.
Adding Amerit Fleet Solutions as its mobile service provider.
