EIA: light duty vehicle energy consumption to drop 25% by 2040; increased oil production, vehicle efficiency reduce US oil and liquid imports

Green Car Congress

LDV energy consumption declines in AEO2014 Reference case from 16.0 quadrillion Btu in 2040 in the AEO2013 Reference case. The rising fuel economy of LDVs more than offsets the modest growth in VMT, resulting in a 25% decline in LDV energy consumption decline between 2012 and 2040 in the AEO2014 Reference case.

Oak Ridge researcher developing autonomous intelligent engines capable of real-time calibration based on driver behavior

Green Car Congress

Calibration is defined as the procedure required to optimize one or more engine performance indices—such as fuel economy, emissions, or engine power—with respect to the engine controllable variables.). They are operated with reference to engine operating points and the values of various engine controllable variables.
