Built by the same experts behind the Catalyst electric bus, the new Proterra ZX5 transit vehicle takes efficiency to the next level. The ZX5 features faster acceleration, industry-leading gradeability and more battery storage. Up to 675 kWh of energy gives the ZX5 maximum range, so the bus can travel more than 300 miles on a single charge. The Proterra ZX5 electric bus is designed, engineered and manufactured by American workers in Proterra’s facilities in California and South Carolina.
