Freightliner FS-65


The Freightliner FS-65 is a cowled bus chassis that was manufactured by Freightliner from 1997 to 2007. Derived from the Freightliner FL-Series medium-duty trucks, the FS-65 was produced primarily for school bus applications, though commercial-use buses and cutaway-cab buses were also built using the FS-65 chassis.
While developed by Freightliner before its acquisition of the Ford heavy-truck product range at the end of 1996 the FS-65 would go on to serve as an indirect successor of the long-running Ford B-Series chassis. After 1998, Ford concentrated bus production towards van-derived chassis, leaving Freightliner to acquire much of the market share of full-size bus production owned by Ford.
The FS-65 chassis was assembled in Gaffney, South Carolina by the Freightliner Custom Chassis subsidiary of Freightliner; as an incomplete vehicle, the chassis was shipped to body manufacturers for final assembly of a bus. After a total of 62,764 units were produced, the final Freightliner FS-65 chassis rolled off the assembly line in December 2006.

Model history

Following the 1991 introduction of the Business Class medium-duty trucks, Freightliner Trucks began development of a school bus chassis based upon the vehicle. In May 1996, the first prototype was unveiled. The first completely new school bus chassis introduced since the 1980 redesign of the Ford B-Series, the Freightliner school bus chassis was scheduled for mid-1996 production; the first Freightliner bus rolled off the assembly line in January 1997.
The FS-65 distinguished itself from other school bus chassis by the standardization of hydraulic anti-lock brakes at the time of its introduction. In tandem with the sloped hood, to aid driver visibility, the design of the chassis used a raised platform for the driver's seat. Although the FS-65 was designed alongside Thomas Built Buses, the Freightliner chassis was made available to other body manufacturers. As a result of the driver's platform, many bus bodies saw revisions to their designs to accommodate the FS-65 chassis, including windshield redesigns or the standardization of high-headroom bodies.
During its production run, the FS-65 chassis saw relatively few changes. For 2002, the Mercedes-Benz MBE900 diesel engines were added to the powertrain line as an option. For 2004, the Caterpillar 3126 became the Caterpillar C7. A redesign of the instrument panel adopted a new instrument cluster, shared with the M2 and Sterling trucks.
In 2001, Freightliner introduced the second-generation Business Class, the M2. In 2004, the Thomas Saf-T-Liner C2 was introduced as the school bus variant of the M2. Sold alongside the C2, the FS-65 remained in production into the 2007 model year; the final Thomas school bus based on the FS-65 was produced on December 13, 2006.
The 2006 discontinuation of the FS-65 marked the end of the FL-Series, as medium-duty production ended after 2004.

Body manufacturers

At its 1997 launch, the FS-65 was widely available to manufacturers throughout the industry with a notable exception. AmTran never offered the chassis with its bus body.
Following the 2001 closure of Carpenter and the 2002 withdrawal of Corbeil from full-size bus production, Blue Bird ended the use of Freightliner chassis, leaving Freightliner subsidiary Thomas Built Buses the sole user of the FS-65 chassis for school bus production.

Powertrain

The Freightliner FS-65 is notable as the first all-new school bus chassis in North America sold exclusively with diesel engines. Initially available with Caterpillar and Cummins diesel engines, in 2002, the FS-65 introduced the Mercedes-Benz MBE 900 diesels as an option.
An Allison 2000 automatic transmission was the standard transmission sold with the FS-65, with the Allison MD3060 as an option. A rarely-ordered option included a Fuller 5-speed manual transmission, making the FS-65 one of the last school buses sold with a manual transmission.
