Ford's retractile exhaust tip system looks ready to rock
Fox News
Ford has filed a patent for an exhaust pipe that can retract and extend to improve the rear clearance on off-road vehicles.
The application, first uncovered by CarBuzz, describes an actuator that can retract the tip of a pipe behind the leading edge of the bumper to improve the departure angle on a vehicle, so it's not dragging behind while driving over rocks.
Many off-road trucks, like the new Bronco, have short pipes that can affect the sound, which can be enhanced with a longer, larger tip.
The F-150 Raptor pickup's pipes are more pronounced and exposed to potential damage.
