Van Hool
Proterra partnered with Van Hool to build that firm's first all-electric coach for North America. The Van Hool CX45E was announced in October 2017, to be available in 2019; it would be followed by a shorter CX35E model. Both of the Van Hool coaches were powered by the Proterra Catalyst E2 battery. A prototype CX45E was exhibited at Busworld Kortrijk in October 2019, the only North American coach shown at the European show.
