Kayoola Solar Bus is a 35-seat electric bus that relies on lithium-ion batteries to power an electric motor coupled to a 2-speed pneumatic shift transmission. Its power is supplemented by a solar array on the roof of the bus that increases the bus’ range. It was designed by engineers at Kiira Motors Corporation and is currently a prototype.
