Electrify Your Fleet

A battery-electric solution enabling zero-emissions performance in an extensive range of market segments. E1 is based on a dependable, proven cutaway package, but with better durability & efficiency, and simplified maintenance.

Secured Power Electronics
Another first in the industry: our products feature 100% of the power electronics, including the battery, motor, driveline, motor controllers, and power/cooling lines, in between the chassis rails while also protecting the vehicle’s critical components. 

Convenient Comfort
Nothing is more comforting than familiarity – except for the smooth, quiet power delivery of EV propulsion in an optimized chassis. With E1, you can have both, with an electric powertrain silently integrating with the convenience of OEM instrument cluster & controls.
