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. History John Clifford "Cliff" Garrett founded the Aircraft Tool and Supply Company in a one-room office in Los Angeles in 1936. In 1938, the company changed its name to Garrett Corporation, consolidating several companies into one with three divisions. The company produced aircraft turbochargers for the war effort in World War II, as well as avionics, environmental controls and other products. In the 1950s, the city of Los Angeles and other municipalities started using turbochargers in their sewage purification operations. By 1952, 20,000 turbocharged engines were in use in the US. In order to explore applications of turbochargers for diesel engines, Garrett separated the turbocharger group from the gas turbine group on September 27, 1954, to form the AiResearch Industrial Division (AID). The first T-15 Turbocharger was delivered to the Caterpillar Company in 1955. It was followed by an order for 5,000 production units, to be installed in the Caterpillar D9 tractor. The industrial division produced turbochargers for construction machinery, railroad locomotives, tractors, ships, powerplants and oil pipeline pumping stations. The T11 automotive turbocharger developed in 1960 expanded turbos to commercial vehicles such as the heavy trucks produced by Mack Trucks, Volvo and Scania. The first turbocharged passenger cars were the Chevrolet Corvair Monza and the Oldsmobile Jetfire in 1962/1963. In the 1960s turbochargers were used in race-cars and sports cars, gaining an association with racing culture and auto-enthusiasts. Company founder Cliff Garrett's death in 1963 was followed by
