US DOE launches cost calculator to compare emissions and operating costs for alternative fuel and conventional vehicles

Green Car Congress

The Vehicle Cost Calculator, an easy-to-use tool that allows users to compare emissions and lifetime operating costs of specific vehicle models, including conventional cars and trucks, as well as vehicles running on alternative fuels such as electricity, ethanol, natural gas, or biodiesel.

U. of Wisconsin RCCI combustion work progressing; modeled 53% gross indicated efficiency in a light-duty engine could result in 2x fuel savings compared to SI gasoline

Green Car Congress

The team has modeled a 53% gross indicated efficiency for the improved light-duty engine. The team has modeled a 53% gross indicated efficiency for the improved light-duty engine. Thermal efficiencies were about 5–7% lower in a light-duty engine, due to the increased heat transfer losses associated with smaller engines.

EPA Trends on EVs and PHEVs; beginning of a “measurable and meaningful impact” on new vehicle fuel economy and emissions

Green Car Congress

The agency’s reasoning was that since alternative fuel vehicle production has generally been less than 0.1% of total vehicle production until very recently, the impact of excluding alternative fuel vehicles was negligible. Fuel economy average for the US fleet, per the Trends report, is 24.1 Click to enlarge.

NPC report to Energy Secretary finds light-, medium- and heavy-duty vehicles could reduce per-mile GHG at least 40% by 2050; additional strategies required for further reductions

Green Car Congress

Projected range of impact of demand, fuel efficiency improvements, and alternative fuel-vehicle systems on light-duty fleet GHG emissions. On a stand-alone basis, all light-, medium-, and heavy-duty vehicles have the potential to reduce per-mile GHG emissions by at least 40% in 2050, relative to 2005 average fleet levels.
