On Tuesday, Proterra revealed that one of its Catalyst E2 Max electric buses just set a new world record for the longest distance traveled by an electric vehicle on a single charge. The bus, which packs a hefty 660kWh of storage—equivalent to 11 Chevy Bolts—drove a total of 1,101.2 miles (1,772.2km) at the Navistar Proving Grounds in Indiana.
