Floating Power was a technology developed in the 1920s by the United States automobile firm of Chrysler, credited mostly to the engineering of Owen Ray Skelton. It was a new means of attaching an engine to its chassis, with the intention of reducing vibration. Four-cylinder engines of the day started and rode rather roughly, transmitting the torque to the whole chassis. By attaching the engine at only two points ("fore-and-aft"), on two points defining an axis that passes through the engine's center of mass, the engine would be able to rotate slightly about this axis and reduce the transmission of torsional vibration to the chassis. One mounting attachment was at the upper front of the engine, directly below the water pump. The rear mount was under the transmission case. A transverse spring went from the bottom of the engine to a rubber lined snubber bracket on the frame rail to limit the rotational travel of the engine.
Advertisers gave this concept its brand name. It was used on the Plymouth and other Chrysler Corporation cars starting in the 1930s. The French firm of Citroën leased the technology for its front-wheel drive car of the 1930s.
