Composite Cab Systems for Medium-Duty EVs
Configurable cab assemblies engineered for Harbinger medium-duty chassis platforms, commercial body integration, and real-world fleet applications.
Engineered for the driver
A purpose-built commercial cab interior — visibility, space, and ergonomics designed for daily medium-duty fleet operations.

The cab system. Not the chassis.
SEVNA manufactures composite cab assemblies — the driver environment, structural enclosure, and mounting interface that sits atop medium-duty EV chassis platforms. We've partnered with Harbinger Motors, who provides the electric chassis foundation. SEVNA provides the cab system that completes the vehicle.

Three rear wall options. One modular platform.
Every SEVNA cab starts from the same composite platform. The rear wall configuration determines the application.
