Looking Back: 7 Questions for New Electric OEM Harbinger
Harbinger Unveils Plug-In Hybrid Vehicle for Medium-Duty Fleets
The medium-duty truck company is expanding its American-made electric vehicle lineup to include a series hybrid model, offering up to 500 miles range.

The Harbinger plug-in hybrid platform features a low-emissions 1.4L inline four-cylinder gasoline engine with a close-coupled 800V generator and a 50-gallon fuel tank.

Harbinger, a medium-duty electric and hybrid vehicle (EV) manufacturer, unveiled a hybrid vehicle for medium-duty fleets.
The new model is an electric vehicle featuring a gas-powered range extender that charges the battery, allowing for an estimated 500 miles of range between charges.
Harbinger’s series hybrid vehicle is currently available for customer pre-orders, and the company plans to begin deliveries to commercial customers in 2026.
“Medium-duty vehicles serve an incredibly diverse range of applications, just like the fleets and operators that rely on them,” said John Harris, co-founder and CEO of Harbinger. “There are some fleets whose needs simply can’t be met with a purely electric vehicle — and we recognize that.”
“Our hybrid is designed for use cases and routes that go beyond what an all-electric system typically supports. The series hybrid delivers the benefits of an electric drivetrain, along with the added confidence of a range extender when needed,” Harris said.
The plug-in hybrid platform features a low-emissions 1.4L inline four-cylinder gasoline engine with a close-coupled 800V generator and a 50-gallon fuel tank. Depending on customer selection, the range extender engine recharges the vehicle’s 140 or 175 kWh battery system.
Harbinger’s electric powertrain delivers up to 1,140 lb.-ft. of torque and 440 hp. The platform’s 800-volt electrical architecture allows rapid charging at DC Fast Charger locations, up to 80% in one hour.
Purpose-Built Chassis for Versatile Applications
Harbinger’s platform, a stripped chassis, was developed for medium-duty vehicles such as delivery vans, box trucks, recreational vehicles (RVs), emergency and disaster response vehicles, and a wide range of additional applications.
The chassis features all major vehicle systems, including the electric drivetrain, range extender engine, high voltage (HV) battery system, steering, brakes, and numerous additional key components and features.
Harbinger designs, engineers, and assembles the chassis and its components in-house at its Garden Grove, California, manufacturing facility. Through its vertically integrated manufacturing process, Harbinger keeps costs low and shields the company and its customers from uncertainty surrounding tariffs.
Once assembled, Harbinger’s chassis is delivered to dealers or customers who work with a third party to upfit the chassis with a commercial or specialty body, as is standard in the medium-duty vehicle industry.
Power Partnerships and Production Milestones
Harbinger recently named Panasonic Energy as its official battery cell supplier and is integrating Panasonic’s 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. The two companies plan to localize cell sourcing by utilizing Panasonic Energy’s new De Soto, Kansas, facility.
Harbinger’s hybrid chassis is also being utilized by recreational vehicle (RV) manufacturer THOR Industries, which operates companies including Airstream, Jayco, Tiffin, and Thor Motor Coach, to deliver industry-leading RVs with up to 500 miles of range.
The introduction of Harbinger’s new model comes on the heels of Harbinger’s recently announced launch of serial production and build of the first 100 units, a milestone the company reached just four years after it was founded in 2021.
In addition, Harbinger also announced its IRA Risk-Free Guarantee program, which guarantees its customers will receive the cost reduction benefit of the Inflation Reduction Act 45W Commercial Clean Vehicle Credit, even if the federal government discontinues the program.
Harbinger at the ACT Expo
Attendees of the Advanced Clean Transportation Expo (ACT Expo), which takes place between April 28 and May 1, 2025, in Anaheim, California, can visit Harbinger at booth #4569 to see the hybrid vehicle in person.
The company announced its new hybrid model in a press conference at Harbinger’s booth at 5:15 p.m. PT on April 28.
Harbinger’s all-electric vehicle will be available for test drives during the Ride and Drive event hosted by ACT Expo:
Tues., April 29, from 11 a.m. - 4 p.m. PT
Wed., April 30, from 10 a.m. - 2 p.m. PT
Participation is first come, first serve.
Harris will be speaking on an ACT Expo Innovative Tech Showcase panel entitled “EV Inflection Point: The Factors Driving Mass Adoption of EVs” at 9 a.m. PT on May 1.
