Honeywell this week issued results of a new survey and said it sees the evolving needs of automakers driving not only turbo adoption globally to 47 percent by 2020, but an increasing 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 evolution of turbocharger applications can be seen in diesel, gasoline and hybrid models from entry level to luxury segments.

According to Honeywell’s 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 numbers indicate,” said Terrence Hahn, Honeywell 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 suppliers 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.”

Technology Themes of Honeywell’s 2015 Forecast

• Adoption of turbocharged 3-cylinder gasoline and diesel engines is emerging as a huge growth trend globally for fuel-efficient entry-level and mid-range vehicles. Honeywell sees an industry compound average growth rate (CAGR) of 30 percent through 2020 resulting in sales of 7 million 3-cylinder turbocharged engines by 2020.
• 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 automakers achieve greater engine performance, without breaching fuel economy regulations, Honeywell says. By 2020, more than 2 million light new vehicles per year will be launched with multi-stage boosting systems. Honeywell is preparing to launch the industry’s first two-stage application with two variable geometry turbos combined in series for ultimate power density and response.

• Globally, diesel engines will 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 penetration to double in North America to 7 percent by 2020, enabled by the latest clean diesel turbocharging and after-treatment technologies.

• Penetration of hybrid powertrains, including “plug-ins,” will be up 4 points to 7 percent of the global light vehicle market. Approximately 25 percent of these vehicles will use turbocharged engines, compared to 10 percent today, opening the door to potential future enhancement with electric boosting and energy recovery.

• In contrast, battery electric vehicles are expected to be only 1 percent of global light vehicle sales in 2020 due to high battery costs and limited range between charges.
