context_page_description: Bus manufacturing, a sector of the automotive industry, manufactures buses and coaches.
context_section_description: The chassis combines:
  A structural underframe
  Engine and radiator
  Gearbox and transmission
  Wheels, axles, and suspension
  Dashboard, steering wheel, and driver's seat
  Chassis will often be built as complete units, up to the point of being drive-able around the factory, or on the public highway to a nearby bodybuilder. The chassis can be front-engined, mid-engined, or rear-engined. Most chassis will mount the radiator at the front, irrespective of engine position, for more efficient cooling.
  Chassis products will often be available in different standard lengths, even produced in articulated variants, and often be used for both bus and coach bodywork, such as the Volvo B10M. The same chassis may even be used for single- or double-decker bus bodywork. Chassis builders may also offer different options for gearbox and engine suppliers. Chassis may also be built in multiple axle configuration.
