EEA: Fuel efficiency improvements of new cars in Europe slowed in 2016

Green Car Congress

The fuel efficiency of new cars sold in the European Union (EU) continued to improve last year but at a slower rate, according to provisional data from the European Environment Agency. of new sales, followed by gasoline vehicles (47%), and alternatively fueled vehicles (3.3%, including electric vehicles).

EPA trends report sees record levels of average new vehicle fuel economy and CO2 emissions for MY 2012; role of new gasoline vehicle technologies

Green Car Congress

EPA projects advanced transmissions (6+ speeds and CVTs), gasoline direct injection (GDI) systems, and turbocharged engines will be installed on at least 15% of all MY 2013 vehicles. The majority of the emissions and fuel savings from current vehicles, EPA noted, is due to new gasoline vehicle technologies. Click to enlarge.

Ford researchers: global light-duty CO2 regulatory targets broadly consistent with 450 ppm stabilization

Green Car Congress

Further, the study compares 450 ppm LDV CO 2 glide paths derived using only vehicle efficiency improvements against those derived using both vehicle and fuel actions. To achieve 450 ppm, WTW LDV CO 2 emissions decrease 25% from 2000 and 34% between 2010 and 2050. In the final step, they added fuel actions to reduce CO 2 (e.g.,
