Bollinger Motors announced its medium-duty, Class 4 all-electric fleet truck, the Bollinger B4. The new medium-duty truck features a cab-forward design with focusing on safety, cargo, and increased turning capabilities, and will be followed by Class 5 and 6 electric trucks.

“The cab-forward design is a radical change from our previous concepts,” said Robert Bollinger, founder and CEO of Bollinger Motors. “And that’s on purpose. We listened to our commercial customers and developed what they need for ultimate efficiency.”

The new Bollinger B4 incorporates years of feedback from dozens of major fleets looking to electrify their vehicles. The result is a cab-forward truck designed from the ground up to offer maximum cargo volume, accommodate unlimited adaptation, and prioritize safety.  

“The cab-forward design also increases both overall cargo space behind the cab and critical downward visibility in front,” noted Kent Harrison, chief product officer of Bollinger Motors. “The B4’s 41-foot turning radius will be better than any comparable wheelbase truck -- which will improve driving dynamics in both rural and urban settings.”  

High-voltage components operate on an 800-volt platform, with batteries consisting of LFP (lithium-iron-phosphate) chemistry, which ensures fleet safety and reduces cost, according to the company. A solid rear-axle e-drive drives the Bollinger B4 to meet the demand for higher payloads. Customers may outfit their B4s with either one or two battery packs to accommodate cost and range requirements. According to Bollinger, range estimates exceed current customer needs and offer roughly 100 miles per battery pack.  

Bollinger Motors will track test B4 chassis cab trucks this fall with numerous fleet customers, upfitters, and charging companies to gather constructive feedback.  

Bollinger B4 customers will benefit from the Inflation Reduction Act recently signed by President Joe Biden. The B4 is expected to be eligible for a 30% tax credit for up to $40,000 under the newly created 45W Commercial EV Tax Credit.

“Commercial fleets need a cost-competitive alternative to traditional ICE vehicles, and these credits, along with Bollinger’s aggressive efforts to deliver a quality product with a lower total cost of ownership, make EV’s a more affordable and viable option than their ICE counterparts,” said Ed Burke, commercial sales director.

Bollinger Motors has been developing medium-duty all-electric trucks since 2015, according to Bryan Chambers, chief operating officer of Bollinger Motors. “Our Class 4-6 engineering and supply chain development means our commercial trucks are on the fast track to production.”  

Bollinger will begin production with the Class 4 Chassis Cabs. Additional Class 5 and Class 6 trucks are set to follow.

The price and release date for the B4 chassis cabs are yet to be announced. 

Bollinger announced in May that it will source and provide all materials for Roush to assemble its all-electric vehicle platforms and chassis cabs.
