A government report subsequently found that, in 2019, new light-duty vehicle fuel economy fell 0.2 miles per gallon (to 24.9 miles per gallon) and pollution increased 3 grams per mile traveled (to 356 grams per mile). A decrease in fuel economy and an increase in pollution had not occurred for the previous five years. [88]
In the example provided by the US DoE in its final rule, an electric car with an energy consumption of 265 Watt hour per mile in urban driving, and 220 Watt hour per mile in highway driving, results in a petroleum-equivalent fuel economy of 335.24 miles per gallon, based on a driving schedule factor of 55 percent urban, and 45 percent highway ...
The fuel consumption is an equivalent measure for cars sold outside the United States, typically measured in litres per 100 km traveled; in general, the fuel consumption and miles per gallon would be reciprocals with appropriate conversion factors, but because different countries use different driving cycles to measure fuel consumption, fuel ...
The high value is obtained when, after the combustion, the water in the exhaust is in liquid form. For the low value, the exhaust has all the water in vapor form (steam). Since water vapor gives up heat energy when it changes from vapor to liquid, the liquid water value is larger since it includes the latent heat of vaporization of water. The ...
The combined fleet fuel economy for new cars and trucks with a GVWR of 10,000 pounds (4,500 kg) or less was projected to average 35.5 miles per gallon (mpg) for the 2016 model year based on the newly-established targets and projected fleet mix.
The procedure for checking a transmission's fluid level depends largely on what you drive. Here are the most common ways to do it. How to check your car's transmission fluid
The oil regulator for North Dakota stated in early December 2013 that he expected as much as 90 per cent of that state's oil would be carried by train in 2014, up from the current 60 per cent. [16] The number of crude oil carloads hauled by U.S. railroads surged from 10,840 in 2009 to a projected 400,000 in 2013. [16]
