EPA annual trends report finds new vehicle fuel economy at record 24.1 mpg; new powertrain technologies rapidly gaining share

Green Car Congress

mpg increase over the previous year and an increase of nearly 5 mpg since 2004. The majority of the carbon and oil savings from current vehicles is due to new gasoline vehicle technologies, the report observed. Since 1975, half of car production has consistently been within several mpg of each other. mpg, which is 0.5

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.
