The CE Series is built to be on time, every time

CE Series Powered by Gasoline

PURPOSE-BUILT FOR THE SCHOOL BUS INDUSTRY

Based on feedback from our customers, we set out to develop a gasoline powered, commercial-grade V8 engine purpose-built for school buses that features similar power and performance to diesel. This means immediate acceleration from a complete stop and greater hill climbing capability. In other words: a no compromise solution for school districts everywhere.
