70 The Shop November 2015 Is the Golden Age of turbocharging upon us? A report by turbo supplier Honeywell shows the evolving needs of automakers will drive not only turbo adoption globally to 47 percent by 2020, but an increased appetite for turbo technology innovations that enhance a vehicle's overall powertrain system, reduce complexity and are tailored to local market needs. Honeywell unveiled its annual survey in advance of the Frankfurt International Motor Show (IAA), where the next evolu- tion of turbocharger applications could be seen in diesel, gasoline and hybrid models from entry-level to luxury segments. According to the survey, automakers are focused on "rightsizing" engine technology, more than simply downsizing engines, to optimize vehicle performance and fuel economy as global regulations continue to drive more fuel efficiency. "The Golden Age of Turbo is gathering momentum globally as the industry num- bers indicate," says Terrence Hahn, Hon- eywell Transportation Systems president and CEO. "But there is a clear demand for more sophisticated turbo technology that covers the entire powertrain performance envelope. Automakers are turning to sup- pliers like Honeywell to meet the unique needs of fuel-efficient 3-cylinder engines, increase power from 4-cylinder engines with advanced aerodynamics, and soon deliver electric boosting and energy recovery systems for advanced hybrid powertrains." Honeywell forecasts that the adoption of turbocharged 3-cylinder gasoline and diesel engines will emerge as an important growth trend globally for fuel-efficient, entry-level and mid-range vehicles. The company sees an industry compound average growth rate (CAGR) of 30 percent through 2020, resulting in sales of 7 mil- lion 3-cylinder turbocharged engines in the next four years. Globally, 4-cylinder engines will continue to represent 75 percent of the turbocharged light vehicle industry in 2020. Honeywell forecasts this turbo engine family will have a 7-percent CAGR through 2020. Multi-stage boosting for diesel engines is another key innovation to help auto- makers achieve greater engine performance, without breaching fuel economy regula- tions. By 2020 more than 2 million light new vehicles per year will be launched with multi-stage boosting systems, the company predicts. Globally, diesel engines are expected to retain an important share of light vehicle sales at nearly 20 percent, due to their lower fuel consumption and CO2 emissions. In particular, Honeywell expects diesel pen- etration to double in North America to 7 percent by 2020, enabled by the latest clean diesel turbocharging and after-treatment technologies. Meanwhile, penetration of hybrid pow- ertrains, including "plug-ins," will be up 4 points to 7 percent of the global light vehicle market, the survey said. Approxi- mately 25 percent of these vehicles will use turbocharged engines, compared to 10 per- cent today, opening the door to potential future enhancement with electric boosting and energy recovery. "Turbo penetration continues to grow as auto makers develop global engine programs which can fill needs in multiple markets. Consumers are adopting fast, and expect the highest levels of quality and reli- ability," said Hahn. performance Turbo Appetite Increasing Automakers are continuing to adopt turbo technology globally as engine downsizing evolves into engine "rightsizing."
