Harbinger Adds Low‑Cab‑Forward Truck to Medium‑Duty Line
Customers Can Choose Battery-Electric or Hybrid Powertrain
Key Takeaways:
- Harbinger unveiled its HC Series Cab hybrid and electric low-cab-forward truck on March 11 at Work Truck Week 2026 in Indianapolis.
- The model expands Harbinger’s medium-duty lineup with a range-extended hybrid platform offering up to 500 miles and added safety features following the Phantom AI acquisition.
- Harbinger plans to roll out additional ADAS capabilities across its electric and hybrid vehicles as it continues growing with new funding and fleet orders.
Harbinger on March 11 unveiled a low-cab-forward truck, the HC Series Cab, expanding its portfolio of medium-duty vehicles.
Garden Grove, Calif.-based chassis and truck manufacturer Harbinger said the truck would be available as both a battery-electric vehicle and a plug-in hybrid model.
Harbinger, which debuted the model at Work Truck Week 2026 in Indianapolis, has historically focused on Classes 4-6 battery-electric chassis and trucks.
But the HC Series Cab is not Harbinger’s first hybrid product. The company unveiled a hybrid stripped chassis at the 2025 Advanced Clean Transportation Expo.
Harbinger chassis are delivered to dealers and customers for the addition of a commercial or specialty body by a third-party upfitter.
Co-founder and CEO John Harris noted at ACT 2025 that fully electric vehicles are suitable for about 80% of medium-duty applications, especially in the last-mile delivery segment, but use cases with longer routes, unpredictable days or limited charging access need a different option.
The HC Series Cab’s range-extended hybrid platform uses a gasoline engine to recharge the batteries, offering a range of up to 500 miles depending on how the truck has been upfitted and used. The hybrid vehicle can also recharge its batteries while parked.
Harbinger said the low-cab-forward architecture enables longer cargo boxes on shorter wheelbases, allowing fleets to increase usable cargo volume without increasing overall vehicle length. The HC Series Cab has a turning diameter of 42 feet on the 158-inch wheelbase option. Three wheelbase options are available: 158 inches, 178 inches and 208 inches.

The HC Series Cab can be upfitted with a variety of bodies, including cargo boxes, stake beds and flatbeds. It has a frame height of around 29 inches at 26,000-pound gross vehicle weight rating to increase the speed of entry, exit and loading.
“The HC Series Cab represents a major expansion of our product line and a defining moment for the medium-duty industry,” Harris said in comments accompanying its unveiling. “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.”
Harbinger is also offering extra safety features on the HC Series Cab for customers following its acquisition of Phantom AI in late February.
Existing trucks came with backup cameras incorporating dynamic trajectory, virtual bumpers and acoustic vehicle alerting systems.
As 2026 progresses, Harbinger plans to equip its medium-duty electric and hybrid vehicles with Advanced Driver Assistance Systems features such as emergency braking, adaptive cruise control, lane keeping and more.
Prior to the launch of the HC Series Cab, Harbinger offered all-electric chassis, plug-in hybrid chassis, step vans and medium-duty trucks with a Sevna cab.
FedEx — which ranks No. 2 on the Transport Topics Top 100 list of the largest for-hire carriers in North America — placed an order for 53 battery-electric step vans in November while also investing in Harbinger.
Overall, Harbinger raised $160 million in a Series C funding round co-led by the transportation giant, investment firm Capricorn’s Technology Impact Fund and recreational vehicle manufacturer Thor Industries.
Elkhart, Ind.-based Thor’s Entegra Coach unit in September unveiled a Class A motor home, the Embark, with a chassis and hybrid powertrain built by Harbinger.
Further investors involved in the latest funding round included venture capital group Ridgeline, a previous Harbinger investor backed by FedEx; investment firm Tiger Global; Leitmotif, a venture capital firm backed by International Motors parent company Volkswagen; and the Coca-Cola System Sustainability Fund. So far, Harbinger has raised $358 million in funding.
