Harbinger has introduced a new series hybrid vehicle aimed at medium-duty truck fleet applications. The electric vehicle includes a gas-powered range extender that charges the battery, offering an estimated 500-mile range between charges.
The hybrid model is now open for pre-orders, with initial deliveries to commercial customers scheduled for 2026.
Designed for Demanding Fleet Applications
John Harris, co-founder and CEO of Harbinger, noted that the new hybrid is built for fleet operators whose routes or demands may exceed the capabilities of a traditional battery-electric vehicle.
“There are some fleets whose needs simply can’t be met with a purely electric vehicle — and we recognize that,” he said. “The series hybrid delivers the benefits of an electric drivetrain, along with the added confidence of a range extender when needed.”
The platform includes a plug-in hybrid system powered by a 1.4L inline four-cylinder gasoline engine paired with an 800V generator and a 50-gallon fuel tank. It can be equipped with either a 140 or 175 kWh battery system. Harbinger’s powertrain produces up to 1,140 lb.-ft. of torque and 440 horsepower. The 800-volt electrical architecture supports DC Fast Charging to 80% in about an hour.
Built on a stripped chassis design, the platform supports a range of medium-duty trucks such as delivery vans, box trucks, RVs, and emergency or disaster response vehicles. The chassis includes essential systems like the electric drivetrain, battery, steering, brakes, and the range extender engine.
All design, engineering, and assembly is handled in-house at Harbinger’s Garden Grove, California, facility. This vertically integrated approach is intended to help control costs and minimize exposure to tariff-related disruptions. Once complete, the chassis is sent to dealers or customers for upfitting with the body style of choice.
Partnering with Panasonic Energy
Harbinger recently named Panasonic Energy as its official battery cell supplier, and is integrating Panasonic’s best-in-class lithium-ion battery cells as standard in its proprietary EV chassis.
Initially, Panasonic Energy will supply Harbinger with battery cells manufactured in Japan, which will be delivered to Harbinger's headquarters in Garden Grove, California.
In the near future, the two companies look to localize cell sourcing by utilizing Panasonic Energy’s new facility in De Soto, Kansas.
More on Harbinger
Harbinger’s hybrid platform is also being used by RV maker THOR Industries, parent company to brands like Airstream and Jayco, to support long-range recreational vehicles. The debut of this new hybrid chassis follows Harbinger’s recent announcement of serial production and the first 100 units built — just four years after the company’s founding in 2021.
The company also recently launched a program to guarantee customers the cost benefit of the Inflation Reduction Act’s Commercial Clean Vehicle Credit, even if the program is discontinued.
