Harbinger introduced a new medium-duty low-cab-forward work truck platform, the HC Series Cab, at NTEA Work Truck Week in Indianapolis.

The vehicle expands Harbinger’s medium-duty lineup and is available in both all-electric and plug-in hybrid versions. The company said the platform is designed to support a wide range of upfits — including box trucks, flatbeds, and stake beds — while improving maneuverability, payload efficiency, and operational flexibility for fleets.

“With the HC Series Cab, fleets no longer have to compromise between payload, maneuverability, range, and

onboard capability,” said John Harris, co-founder and CEO of Harbinger. “We engineered this platform to outperform legacy diesel options while unlocking new advantages through electrification and our range-extended hybrid system.”

Low Cab Forward Design Targets Urban Fleets

The HC Series Cab uses a low cab forward (LCF) architecture that allows longer cargo bodies to be installed on shorter wheelbases, helping fleets increase cargo capacity without increasing overall vehicle length.

The truck carries a gross vehicle weight rating of up to 26,000 pounds and is designed to compete with traditional medium-duty trucks while offering the benefits of an electric platform.

"Harbinger vehicles are designed from the ground up as electric platforms," said Fred DePerezl, SVP of sales. "That fundamentally simplifies maintenance—fewer moving parts, fewer oil changes, no traditional transmission systems—translating into fewer interruptions and more predictable operating performance.”

Harbinger said the design is particularly suited for urban and regional fleet applications where maneuverability and visibility are important. The platform offers a turning diameter of 42 feet on the 158-inch wheelbase configuration, which the company says is tighter than comparable trucks from Ford and Isuzu.

Additional features aimed at fleet operations include a low frame height of about 29 inches to ease loading and unloading, improved sightlines from the cab-forward driving position, and independent front suspension designed to improve ride quality and handling in stop-and-go routes.

Electric and Hybrid Powertrain Options

The HC Series Cab is offered as both a fully electric truck and a range-extended plug-in hybrid model.

In the hybrid configuration, a gasoline engine recharges the vehicle’s batteries, allowing the truck to achieve up to 500 miles of range depending on configuration and operating conditions.

The hybrid system also allows the truck to recharge while parked without an external charger, enabling continuous power generation for tools and jobsite equipment.

Both EV and hybrid versions support an onboard AC inverter capable of delivering up to 15 kilowatts of exportable power, allowing crews to operate external equipment directly from the vehicle.

Platform Built for Uptime and Serviceability

Harbinger said the HC Series Cab was developed on the company’s proprietary electric-vehicle architecture

rather than on an internal-combustion chassis.

The vertically integrated platform includes components designed and manufactured in-house, including the powertrain, battery system, steering, and braking systems.

Shared components across Harbinger vehicles are intended to simplify parts inventories and maintenance processes for fleets operating multiple vehicles on the platform. Electric drivetrain architecture also reduces routine maintenance requirements compared with diesel-powered trucks.

The chassis is designed for durability targets exceeding 450,000 miles and a service life of up to 20 years.

Driver Safety and Technology

Harbinger said the HC Series Cab introduces additional driver-assistance technologies to the medium-duty segment, where advanced safety features have historically been limited.

Existing safety systems include backup cameras with dynamic trajectory guidance, virtual bumper detection, and acoustic vehicle alerting systems.

Following Harbinger’s acquisition of Phantom AI, the company said it plans to add advanced driver assistance features, including automatic emergency braking, adaptive cruise control, and lane-keeping systems, to its medium-duty vehicles beginning in 2026.

"Drivers in this segment are not just commuting around town," said DePerezl. "They’re working—they’re operating equipment, managing tight schedules, and navigating unpredictable conditions that create real physical and mental fatigue. Advanced driver assistance reduces the cognitive load in traffic and high-density environments, helping drivers stay focused and confident throughout the day."

Availability and Configurations

The HC Series Cab is available for order now and can be configured with multiple wheelbases and body options to support various commercial applications.

Wheelbase configurations include:

• 158-inch wheelbase (Class 4–6) with up to 22,000 GVWR 

• 178-inch wheelbase (Class 5–6) with up to 26,000 GVWR 

• 208-inch wheelbase (Class 5–6) with up to 26,000 GVWR
