Electric buses have become more efficient with the Proterra® ZX5, refined based on a decade of delivering battery-electric transit buses. Proterra’s fifth-generation vehicle, the ZX5 electric bus, incorporates a purpose-built platform proven through more than 25 million miles in service. With the new generation of Proterra batteries, the ZX5 electric bus has more energy onboard to deliver a longer range. Increased energy density enables the ZX5 to have up to 738 kWh of energy onboard, one of the most onboard energy storage options of any 40-foot electric transit bus.
