Diesel Turbochargers

Garrett continues to pioneer diesel turbo technologies that help elevate the dynamic between fuel efficiency, emissions reduction and driveability in cars and light commercial vehicles. Our innovative boosting systems open up engine downsizing options for automakers through class-leading power density, simultaneously driving performance, and helping improve fuel consumption and reduce NOx and CO2 in real world driving conditions.

Performance & Reliability

Garrett turbo systems – from the renowned Variable Geometry Turbo (VNT) architecture to innovative Two Stage designs – leverage engineering advances in aerodynamics, materials, bearings and electric actuation to set new benchmarks for performance and reliability.
