The Proterra ZX5 Electric Transit Bus

Go the Distance

Electric buses have become more efficient than ever with the Proterra ZX5, the next evolution in zero-emission transit.

The Proterra ZX5 is refined based on a decade of delivering the Catalystregistered — the most popular electric bus in North America. Since 2004, the EV industry has evolved toward full fleet electrification, and Proterra buses have evolved with it. Proterra’s fifth-generation vehicle, the ZX5 electric bus employs the same technology that broke the world record for longest EV range, with a purpose-built platform proven by 40+ million service miles. Made in the USA, the ZX5 features faster acceleration, industry-leading gradability, and the most battery storage on the road today for any 40-foot electric bus, offering a range of more than 300 miles per charge.

Now you can make the shift to an electric fleet without compromising on vehicle performance.

Bank on the Savings


Proterra ZX5 vehicles aren’t just clean and quiet. They’re also far more economical than conventional transit vehicles. Imagine not having to maintain an engine, fuel system, cooling system or exhaust system. With Proterra, all that effort and expense is a thing of the past. Combining significantly lower maintenance costs with the stable cost of electricity and exceptional fuel economy delivering up to 25 MPGe, our customers have the potential to achieve over $400,000 in operational savings per vehicle.
