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.

John Clifford "Cliff" Garrett founded the Aircraft Tool and Supply Company in a one-room office in Los Angeles in 1936.

[9][6] The industrial division produced turbochargers for construction machinery, railroad locomotives, tractors, ships, powerplants and oil pipeline pumping stations.

The oil crisis of the 1970s made federal regulators put pressure on car manufacturers to reduce exhaust emissions.

[17] Garrett has developed the world's smallest turbo for the Tata Nano[18][19] as well as for the 100-liter engine of the Caterpillar mining truck.

[citation needed] On September 21, 2020, Garrett Motion announced its intention to file for Chapter 11 bankruptcy and be acquired by KPS Capital Partners.

They are designed to be smaller than previous turbo generations, have higher fuel efficiency, more torque, and meet emissions standards.

[28] They have nine moveable vanes, an electrohydraulic actuator and a proportional solenoid for variable control throughout the engine's power curve.

The dual-stage used in the Audi A6/A7 three liter V6 engine however runs both turbochargers at a lower pressure mode and some use one larger turbo followed by a smaller one.

This creates a rolling rather than sliding mechanism between parts intended to reduce the amount of pressure required to achieve airflow.
