The company develops and manufactures major vehicle systems in-house, including powertrains, battery systems, steering and brakes. Its platform is built around an electric vehicle stripped chassis, which provides the main systems needed for different vehicle applications.

In March, Harbinger unveiled its HC Series Cab, which includes a gasoline range extender. Depending on the configuration, it can provide a driving range of up to 500 miles and up to 15 kilowatts of exportable power. This allows crews to power equipment without carrying a separate generator.
