In November 2025, Garrett's next-generation exhaust bypass turbocharger was successfully selected as one of the "Top 100 New Supply Chains in China's Automotive Industry." This core component, specifically designed for hybrid and extended-range electric vehicle (EREV) power systems, addresses three major pain points in hybrid operation: "low exhaust temperature makes boosting difficult, frequent start-stop leads to wear, and power transition needs to be smooth." Through systematic upgrades in aerodynamics, materials, and control technology, the overall efficiency of the unit has surpassed 54%, perfectly adapting to the National VI B and future stricter emission regulations. This also marks the acceleration of localization in R&D by foreign component giants, deeply aligning with the demand rhythm of China's new energy market. Unlike turbochargers designed for traditional fuel vehicles, this product has been specifically optimized for the unique operating conditions of hybrid models: addressing the issue of "intermittent engine operation and low exhaust temperature leading to weak turbine drive energy," it employs lightweight, heat-resistant materials to create a low-inertia rotor that can quickly establish boost pressure even at low exhaust temperatures, thoroughly resolving the experience pain points of "engine engagement delay and abrupt power transition." It enhances the water-cooling structure and oil circuit design to resist carbon buildup, reducing wear on bearings and seals from frequent thermal cycling, significantly improving durability. Equipped with a high-precision electronic wastegate (EWG), it can accurately control boost pressure, balancing power response, fuel consumption, and emissions, while also accelerating catalyst warming through strategic backpressure management, thus shortening the emission purification time to meet the National VI B and RDE real driving emission requirements. To adapt to the Chinese market, Garrett's engineering team in China has conducted joint calibration based on typical scenarios such as high-density congestion, high temperature and humidity, and thin air at high altitudes. By utilizing digital simulation, they have shortened the validation cycle, and local procurement of core components has improved delivery efficiency and flexible production capacity. The platform design of this turbocharger can cover multiple engine displacements, reducing R&D and production costs for automakers, while also enabling hybrid models to achieve noticeable fuel consumption reductions in congested and stop-start scenarios. This award not only affirms the product's capabilities but also reflects the upgrading trend of the supply chain in China's hybrid vehicle sector: foreign giants are deeply participating through "localized R&D and scenario-based adaptation," providing mature solutions for automakers to balance performance, fuel consumption, and emissions, thus promoting the development of hybrid models towards greater efficiency and reliability.
