Downspeeding and supercharging with transmission optimization can deliver fuel economy improvement over downspeeding and turbocharging

Green Car Congress

MAY 9, 2012

Researchers from Southwest Research Institute (SwRI) and Eaton have demonstrated the application of downspeeding and supercharging a diesel vehicle, in conjunction with optimizing transmission gear ratios and the shift schedule, to deliver a greater improvement in fuel economy than a downsped and turbocharged configuration.

National Research Council Study Finds That Available Technologies Can Result in Significant Fuel Savings for Passenger Vehicles Over the Next 15 Years, But at Higher Purchase Prices for Consumers

Green Car Congress

JUNE 4, 2010

Using a 2007 base vehicle, the committee estimated the potential fuel savings and costs to consumers of available technology combinations for three types of engines over that timeframe: spark-ignition gasoline, compression-ignition (CI) diesel, and hybrid. The study was sponsored by the National Highway Traffic Safety Administration.
