Bollinger Motors, a commercial electric vehicle maker and subsidiary of Mullen Automotive, announced a starting MSRP of $158,758 for the 2025 Bollinger B4 Chassis Cab medium-duty battery-electric truck.

According to Bollinger, the B4 Chassis Cab is an all-new, all-electric Class 4 commercial truck designed with extensive fleet and upfitter input. The unique chassis design protects the 158-kwh battery pack and components, offering capability and safety in the commercial market.

“Our team has listened to our customers and created a world-class electric truck to fill an important segment of the Class 4 commercial fleet market,” Jim Connelly, chief revenue officer for Bollinger Motors, said. “We feel that we are bringing a versatile and valuable truck to market at a competitive price point. When combined with the variety of incentives available to potential customers, we believe the B4 makes the fleet transition to electric a no-brainer.”

The company commenced serial production of the B4 in September 2024 and will begin delivering vehicles to customers in October 2024. The all-electric Bollinger B4 is available to order through Bollinger’s national dealer network.

Qualified for Tax Incentives Over $100K

The 2025 B4 will be eligible for combined federal and state incentives of more than $100,000. The base B4 can be enhanced with dealer accessories and several factory options, including an e-PTO unit available in January, to meet a fleet’s specific needs.

Earlier this year, Bollinger Motors received IRS approval as a qualified manufacturer for clean vehicle credits under the Inflation Reduction Act of 2022 (IRA). This designation enables the Bollinger B4 chassis cab to qualify for the IRA’s new credit for qualified commercial clean vehicles, providing eligible purchasers a tax credit of up to $40,000 per vehicle.

In addition, Bollinger Motors was recently CARB certified, providing the pathway to California’s Hybrid and Zero-Emission Truck and Bus Voucher Incentive 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 savings. Additional available state and local incentives could push the total above $100,000.
