Overview
Proterra DuoPower™

Proterra designed and developed an innovative drivetrain system for its Catalyst® E2 electric bus and worked with AxleTech for its engineering and manufacturing expertise, resulting in a drivetrain with optimal operating and packaging efficiency. The fully-integrated powertrain with new 2-speed gearboxes is a major contributing factor in achieving a 20% efficiency improvement over the previous generation powertrain. Proterra recently set the world record for the longest distance traveled by an electric vehicle on a single charge: 1,101.2 miles.
