Freightliner C2
The Freightliner C2 is a Type C conventional bus chassis manufactured by Daimler Truck North America, used for school bus applications. It was introduced in 2004 as the replacement for the FS-65.

Body manufacturers
As a bus chassis, the C2 is only used by Thomas Built Buses as the basis for the Thomas Saf-T-Liner C2. As Thomas is a subsidiary of Freightliner, there are no plans by other body manufacturers to utilize the C2 chassis. However, the standard Freightliner M2 chassis is available to the commercial and shuttle bus industry as a cutaway cab as the Freightliner B2.Powertrain
