Delivering the best fuel economy safely, with a lightweight, highly durable bus

The Proterra Catalyst® zero-emission, battery-electric bus is built on a platform designed to provide both flexibility and durability. The highly efficient batteries safely deliver reliable energy with the modularity to adapt to a range of urban and regional routes.
An advanced electric drivetrain delivers optimal energy efficiency at a lower operating cost than fossil-fuel combustion engines. And the carbon-reinforced composite body resists impact and corrosion while providing a significantly longer lifespan than conventional transit vehicles.
