The Automotive Turbochargers Report
Turbocharging, once largely the domain of high-performance, sophisticated engine configurations, is now a key powertrain component technology for a wide range of vehicle applications and segments. In the past, the major design requirement encouraging the use of forced induction in performance vehicles was to increase peak engine performance in terms of horsepower (hp). Now that the technology has advanced in its integration, control strategy, and cost parameters to give value-for-money fuel efficiency gains, the technology sees standard implementation in applications as diverse as the VW Golf, Honda CR-V, Toyota Hilux, Nissan X-Trail, and Mercedes-Benz C-Class.
Following increasingly stringent emission regulations, small-displacement turbocharged engines are preferred by engineers as they are acknowledged as an important route to the improvement of fuel economy. The concept behind induction charging—be it through turbocharging or supercharging—is to increase the amount of air and fuel in the vehicle’s engine. This process helps to increase the engine power output. To this end, intake air is compressed by a compressor, which is driven by the pressure of the exhaust gas (turbocharger), directly from the engine crankshaft (mechanical supercharger), or by an electric motor (electric turbo/supercharger). A small turbocharged engine can achieve the same power output as a much larger engine—without compromising fuel economy—under lower power demand conditions. Every design that helps to reduce the size of the engine or components must be countered by a boost to available power from the engine through supercharging and turbocharging.

The Automotive Turbochargers Report takes in in-depth look at the technologies drving development in this area. The report features component demand analysis at both a global and regional level. Also included is analysis of new technologies in turbocharging, as well as IHS Markit forecasts of engine-production by aspiration type. The report then looks at the structure and main players in turbocharging, with market share analysis and OEM/supplier relationships.
Updated January 2020
Automotive OEMs are currently focusing on rightsizing engine technology, instead of merely downsizing engines to achieve fuel economy gains. Turbocharging will continue to play a crucial role in this concept. Development of turbochargers for the next-generation small gasoline engines continues apace with three objectives: minimizing the weight added to the powertrain; making power potential equal to, or better than, larger engines; and meeting global emission norms. IHS Markit expects global turbocharger component production volume featured in gasoline engines to significantly grow during 2018–25. On the other hand, global turbocharger component production volume featured in diesel engines is expected to slow down during the same period. Region-wise, the Chinese turbocharger market will observe the highest market growth in terms of demand by volume and is expected to be greater than the European demand for turbocharges by 2023. IHS Markit forecasts turbocharger volumes in China to greatly grow in the period 2018–2025. Major market drivers that IHS Markit has identified are emission and fuel economy legislations, engine downsizing, and competitive advantages of turbocharging technology over alternative options. The use of variable geometry turbocharger technology in gasoline engines is an emerging trend. Suppliers have made strides specifically with this technology e.g., in 2017, BorgWarner developed a specialized variable turbine geometry (VTG) turbochargers for gasoline vehicles. In terms of technology penetration, global engine production volume featuring TCI technology is expected to remain popular in 2018-25. Garrett Motion, BorgWarner, MHI, IHI, and BMTS Technology were the top-five players in 2019.These suppliers are expected to continue dominating the turbocharger market.
