Garrett Motion Inc., formerly Honeywell Transportation Systems and Honeywell Turbo Technologies, is an American company primarily involved in engineering, development and manufacturing of turbochargers and related forced induction systems for ground vehicles from small passenger cars to large trucks and industrial equipment and construction machinery. It originated as part of Garrett AiResearch's Industrial Division in Phoenix, Arizona, in 1954, after which they entered a contract to provide 5,000 turbochargers for the Caterpillar mining vehicle. It manufactured turbochargers for railroads and commercial trucks. The business produced approximately $3.6 billion in revenue in 2021. Garrett Motion is also involved in motorsports providing turbochargers and forced induction systems, solutions and related equipment to racing teams and various forms of automobile racing and professional competitions. In 2004, the business became part of American industrial conglomerate Honeywell International, Inc., as their Transportation Systems division. In 2018, it was spun off to become an independent company under the Garrett Motion name with corporate headquarters in Rolle, Switzerland.

In an internal combustion engine, a turbocharger is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake air, forcing more air into the engine in order to produce more power for a given displacement.
