Lightweight Composite Body
About the Lightweight Composite Body
There are many compelling benefits of Proterra’s purpose-built vehicle including the all-composite body we have developed. The functional design better addresses the needs of drivers, maintenance crews and passengers.
The available space is efficiently used and component placement is optimized for performance while also providing an attractive aerodynamic design.
The composite body provides a 20-40% weight reduction. The body is stronger and more resistant to crashes, minor incidents, salt and other chemicals as well as the elements resulting in a 40%+ longer life. Current transit agencies operating buses with composite bodies have data that demonstrates savings of up to 90% over comparable conventional body repair costs.
The composite body also offers improved safety given the energy absorbing crash-resistant characteristics of the composite structure.
Measurable benefits include:
- Increased seating capacity
- Lower repair and maintenance expenses
- Faster boarding and exiting of passengers
- Improved passenger safety
- Longer vehicle life
