Cab Systems
Composite cab assemblies with configurable rear walls, door options, and a modular architecture designed for medium-duty commercial EV applications.
Three rear wall options for every application
The rear wall determines how the cab interfaces with the commercial body. Choose the configuration that matches your application and body type.
Solid Rear Wall
A fully enclosed rear cab wall that provides complete separation between the cab and the body. The solid rear wall is the standard configuration for box truck, refrigerated, and dry freight applications where cargo security and thermal separation are priorities.
Walk-Through Rear Opening
An open middle pass-through between the cab and cargo area. Designed for walk-in delivery and other specialty applications where operators need frequent interior access without exiting the vehicle.
Full Cutaway Rear Opening
A fully open rear wall that gives body builders and upfitters maximum flexibility. The full cutaway provides an unobstructed rear interface for mounting shuttle bus, vocational, specialty, RV, or custom commercial bodies.
Standard or motorized passenger-side access
Dual Swing Doors
Standard driver and passenger swing doors provide conventional cab access. Available across all rear wall configurations and wheelbase options.
Standard on all configurations
Motorized Articulating Door
An optional passenger-side motorized door designed for delivery, bus, and shuttle applications. Provides wide-opening access for high-frequency boarding and curbside delivery operations.
Optional — passenger side

Designed around the driver
The SEVNA cab interior prioritizes driver comfort, visibility, and operational ergonomics. Generous headroom, low step-in height, and a thoughtfully arranged instrument panel create a driver environment suited for long shifts and demanding commercial routes.
- Generous headroom accommodating drivers up to 6'3"
- Low step-in height for reduced fatigue on frequent stops
- Wide forward visibility and optimized mirror placement
- Climate control and reduced NVH from composite construction
Cab-to-chassis interface
Every SEVNA cab is engineered to mount directly to Harbinger medium-duty chassis platforms. The mounting interface is designed for repeatable, production-grade assembly across all three wheelbase options.
