What you need to know:
- At Work Truck Week 2026, Harbinger unveiled the HC Series Cab, a low cab forward (LCF) electric and plug-in hybrid medium-duty truck designed to reduce fleet operating costs while providing mobile jobsite power
- The 26,000-lb GVWR medium-duty work truck supports multiple upfits and allows longer cargo boxes on shorter wheelbases, improving payload capacity and urban delivery efficiency
- A range-extended hybrid powertrain delivers up to 500 miles of range and 15-kW exportable onboard power, enabling crews to run tools and jobsite equipment directly from the truck
- Built on a vertically integrated electric truck platform, the vehicle targets 450,000-mile durability, lower maintenance, and includes ADAS safety technologies such as automatic emergency braking and adaptive cruise control
At Work Truck Week 2026 in Indianapolis, Garden Grove, California-based commercial vehicle manufacturer Harbinger has unveiled its all-new HC Series Cab, a medium-duty, low cab forward (LCF) truck now available in both electric and plug-in hybrid configurations.
Designed for worksites, the HC Series Cab emphasizes maneuverability, driver comfort, safety, and lower operating costs. Beyond serving as a work truck, the vehicle doubles as a mobile power station, providing sustained electricity for tools and equipment for extended periods.

Flexibility and cargo efficiency
The new low cab forward HC Series Cab expands Harbinger's medium-duty lineup, built to handle a wide range of work applications. Fleets can configure the truck with cargo boxes, stake beds, flatbeds, and more, providing operators the versatility to move more payload in tighter spaces.
Thanks to its LCF design, the HC Series Cab can accommodate longer cargo boxes on shorter wheelbases, boosting usable cargo volume without increasing overall vehicle length. With a 26,000-pound GVWR and competitive payload capacity versus segment leaders, the truck combines traditional workhorse performance with the efficiency and sustainability of an electric platform.

Extended range, exportable power, and jobsite capability
Harbinger's range-extended hybrid platform pairs battery-electric drive with a gasoline-powered generator that recharges the battery pack, delivering a driving range of up to 500 miles, depending on the vehicle’s upfit and duty cycle. The range extender also allows the truck to recharge its batteries while parked, removing the need for external charging in certain field operations.
The platform supports full power take-off (PTO) capability, allowing operators to run hydraulic systems and body-mounted equipment directly from the vehicle. Harbinger is also introducing an onboard AC inverter option capable of delivering up to 15 kilowatts of exportable power on both electric and hybrid versions of the HC Series Cab.
This onboard power system allows crews to run tools and jobsite equipment directly from the truck, effectively turning the vehicle into a mobile power source. In the hybrid configuration, onboard generation can sustain continuous 15-kilowatt power export, eliminating the need for separate generators and helping fleets maintain longer operational uptime in the field.

Built for tight routes heavy loads, and frequent stops
The HC Series Cab was designed and engineered to handle the daily challenges faced by urban and regional fleets, where tight streets, frequent stops, and heavy payloads are the norm. The truck's low cab forward architecture improves maneuverability and visibility while supporting efficient operations in dense city environments.
Some key performance highlights include:
- Best-in-class 42-foot turning diameter on the 158-inch wheelbase, improving maneuverability in tight streets and jobsite spaces.
- Low frame height of about 29 inches at GVWR, helping speed up driver entry, exits, and cargo loading.
- Low cab forward driving position that enhances sightlines and supports improved safety in urban settings.
- Independent front suspension and the responsive characteristics of an electric powertrain, delivering a smoother and quieter ride.

Built for uptime, designed for drivers
The HC Series Cab is built on Harbinger's proprietary, vertically integrated electric platform, rather than adapting a traditional internal combustion chassis. The company designs and manufactures its core vehicle systems in-house—including the powertrain, battery system, steering, and braking components—allowing tighter integration, lower costs, and improved performance compared with electric trucks retrofitted from diesel or gasoline platforms.
Shared components across Harbinger vehicles also help fleets simplify maintenance, reduce parts inventories, and improve uptime. The truck's electric drivetrain minimizes routine service requirements, while a modular front-end design allows faster repairs and lowers total cost of ownership. The platform is engineered for durability as well, with service life targets exceeding 450,000 miles.
Beyond the hardware, Harbinger is also focusing on driver safety and comfort, areas where the medium-duty segment has often lagged behind. Harbinger trucks already include safety features such as backup cameras with dynamic trajectory, virtual bumpers, and acoustic vehicle alerting systems.
Following its acquisition of Phantom AI, the company is expanding its advanced driver assistance systems (ADAS) portfolio. Beginning in 2026, Harbinger's medium-duty electric and hybrid trucks will offer features such as automatic emergency braking, adaptive cruise control, and lane-keeping assistance, addressing growing fleet demand for technologies that enhance driver protection and overall road safety.

"The HC Series Cab represents a major expansion of our product line and a defining moment for the medium-duty industry," said John Harris, co-founder and CEO of Harbinger. "For too long, fleets have had to compromise between payload, maneuverability, range and onboard capability. We engineered this platform to outperform legacy diesel options while unlocking new advantages through electrification and our range-extended hybrid system to enable real work in the field."
