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. This packaging design allows for the low-floor chassis layout, while also protecting the vehicle’s critical components.

The Silent Intersection of Comfort & Quality

Our years of experience in automotive engineering have also taught us how to design for an optimized user experience. Enabled by quieter electric propulsion, optimized ride dynamics and body design, and quality materials, our products enjoy lower NVH levels (noise, vibration, harshness) that benefit both passengers and workers.

Convenient Comfort
The Silent Intersection of Comfort & Quality

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
