Study estimates fuel economy improvements to US light-duty vehicles from 1975–2018 saved 2T gallons of fuel, 17B tons of CO2

Green Car Congress

A team from the University of Tennessee and the National Renewable Energy Laboratory (NREL) has the fuel savings due to fuel economy improvements over the past 43 years amount to approximately two trillion gallons of gasoline. Estimated attribution of fuel savings due to fuel economy improvements to light-duty vehicles since 1975.

WUSTL researchers demonstrate solar-panel-powered microbial electrosynthesis to produce n-butanol from light, CO2 and power

Green Car Congress

A team of biologists and engineers modified Rhodopseudomonas palustris TIE-1 (TIE-1) so that it can produce a biofuel using only three renewable and naturally abundant source ingredients: carbon dioxide, solar panel-generated electricity and light. The results are reported in an open-access paper in the journal Communications Biology.

Mercedes-Benz B-Class Electric Drive reduces lifecycle CO2 emissions by as much as 64% compared to B 180 gasoline model

Green Car Congress

CO 2 emissions of the B-Class Electric Drive compared with the B 180 gasoline-engine variant [t/car]. The Mercedes-Benz B-Class Electric Drive ( earlier post ) delivers up to 64% lower CO 2 emissions than the equivalent B 180 gasoline model (when charged with hydroelectricity), according to Mercedes-Benz and TÜV Süd.

ICCT: decline in diesel sales will have negligible impact on attainment of European CO2 emission standards

Green Car Congress

The current decline is ales of diesel light duty vehicle in Europe does not put EU CO 2 targets out of reach of automakers, according to a new analysis by the International Council on Clean Transportation (ICCT). —The ICCT.

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

Green Car Congress

Broadly, the Ford team found that new light-duty vehicle fuel economy and CO 2 regulations in the US through 2025 and in the EU through 2020 are consistent with the CO 2 glide paths. The overall ethanol volume blend share in the gasoline/ethanol fuel pool grows from 14% (10% by energy) in 2020 to 30% (22% energy basis) in 2030.

New Delphi Technologies 500+ bar GDi system cuts gasoline particulate emissions by up to 50%, reduces fuel consumption

Green Car Congress

Reducing engine-out emissions cuts tailpipe emissions in the crucial period before catalyst light-off and reduces the need for costly aftertreatment systems. The industry has long recognized that increasing injection pressure to 500+ bar could substantially cut engine-out particulates while improving CO2 emissions and fuel economy.

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.
