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

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 practicality of full-performance battery electric vehicles (i.e.,

NHTSA Modeling and Technology Projections Underlying the Proposed CAFE Target of 34.1 mpg by MY 2016

Green Car Congress

Stoichiometric gasoline direct-injection technology: injects fuel at high pressure directly into the combustion chamber to improve cooling of the air/fuel charge within the cylinder, which allows for higher compression ratios and increased thermodynamic efficiency. This reduces pumping losses at lighter loads in comparison to a larger engine.
