Which company manufactures the CE Series school bus?

The company that manufactures the CE Series school bus is IC Bus.

The IC Bus CE Series is a Type C conventional school bus produced by IC Bus, the bus-manufacturing division associated with International and Navistar. The model was introduced around 2000 as the International IC, short for Integrated Coach, before adopting the CE-Series name in the early 2000s.

Its defining feature was an integrated chassis and body. That arrangement distinguished it from many earlier school buses built by fitting a separate bus body onto a truck chassis. The CE was initially based on the International 3800, then moved to the International 3300 and, for the third generation, the International MV platform.

The CE is often confused with the International truck models that provide its underlying chassis, but the complete school bus is an IC Bus product. It is also easy to mistake it for a Blue Bird Vision or Thomas Saf-T-Liner C2 because all are competing Type C buses with a hooded layout. IC Bus has offered diesel, alternative-fuel, and electric versions of the CE line.
