Penetration of vehicles with improved fuel economy and safety over the past decade has been tremendous. Over 80 million new vehicles have been purchased in the last five years, representing more than 25 percent of the U.S. vehicle fleet. Progress . The so-called Corporate Average Fuel Economy, or CAFE, standards may be a mouthful, but it’s fair to say that all motorists in the U.S. today have experienced their impact.
The Safer Affordable Fuel-Efficient (SAFE) Vehicles Rule would amend existing Corporate Average Fuel Economy (CAFE) and tailpipe carbon dioxide emissions standards for passenger cars and light trucks and establish new standards covering model years through The proposal would retain the model year standards for both programs. Fuel economy is included because achieving high fuel economy and low emissions together makes the engineering effort more difficult. Emissions and fuel economy are interrelated because both are influenced by the engine combustion system design. In practice, the stringency of emission standards determines the importance of this interrelationship.
In , the Obama administration approved fuel economy standards that required automakers to average miles per gallon across their fleets of vehicles by to reduce greenhouse gas emissions. In a progress report released in December, the Environmental Protection Agency said fuel economy for new vehicles sold in the United States had improved 26 percent from to , to miles.

Ebook Analyzing Fuel Systems Technology for Fuel Economy and Emissions (S P (Society of Automotive. Bythe EPA said, the standards would cut U.S.
oil consumption by million barrels of oil per day compared with levels, save $ trillion in fuel costs and result in an average fuel. NHTSA's Corporate Average Fuel Economy (CAFE) program and EPA's light-duty vehicle GHG emissions program set standards for passenger cars, light-duty trucks, and medium-duty passenger vehicles.
By Model Year (MY)these vehicles must meet an estimated combined average fuel economy of to miles per gallon or higher. Fuel economy and emissions standards are typically applied to the vehicles that a company sells within a country, rather than the vehicles that a particular country produces.
For instance, U.S.-manufactured vehicles have to meet European standards for vehicles sold in Europe, and Japanese standards for those sold in Japan. EPA’s Approach. EPA regulates the emissions from mobile sources by setting standards for the specific pollutants being emitted.
EPA established progressively more stringent emission standards for carbon monoxide, hydrocarbons, nitrogen oxides, and particulate matter, starting in the mids for on-road vehicles and in the early s for nonroad engines and equipment. Progress in fuel systems to meet new fuel economy and emissions standards.
Warrendale, PA, Society of Automotive Engineers, c p. (SP) Includes bibliographical references. TLF8P77 “International Congress & Exposition, Detroit. driving, the average on-road fuel economy for new cars and light trucks is expected to be about mpg byup from mpg for the average vehicle on the road today (EIA ).
2 Fuel savings calculation based on the following assumptions: base vehicle fuel efficiency of miles per gallon on government tests. The most recent set of CAFE/GHG standards, termed the National Program, 1 cover model years (MY) and call for an average light-duty vehicle fleet fuel economy of miles per gallon (mpg) by and mpg by 2 The carbon dioxide (CO 2) emission standard by is grams/mile, which is equivalent to mpg.
The committee recognizes that U.S. government “feebates” based on the fuel consumption of LDVs could have a role as a complement to LDV fuel economy and GHG emissions standards to facilitate and accelerate the introduction of significantly more efficient vehicles into the market to the meet the timing of the goals.
A New York Times analysis found more than 60 environmental policies officially rolled back under Mr. Trump and another 34 rollbacks still in progress.

Automobile and Truck Fuel Economy (CAFE) and Greenhouse Gas Standards Congressional Research Service Summary In recent years, as oil and gasoline prices have risen and concerns over greenhouse gas emissions and climate change have grown, there has been a resurgence of interest in the fuel economy and.
InNHTSA established final passenger car and light truck CAFE standards for model yearswhich the agency projects will require in model yearon average, a combined fleet-wide fuel economy of mpg. As part of the same rulemaking action, EPA issued GHG standards, which are harmonized with NHTSA’s fuel economy.
If Trump Weakens Fuel Economy Standards, American Innovation Will Be The Price to give automakers some relief from fuel economy and emissions mandates, which require them to achieve a.
New fuel economy standards will save consumers an estimated $ trillion in fuel costs over the life of their vehicles or an estimated $8, in. As oflight-duty trucks must meet the same emissions standards as passenger cars.
Tier II regulations also defined restrictions for the amount of sulfur allowed in gasoline and diesel fuel, since sulfur can interfere with the operation of advanced exhaust treatment systems such as selective catalytic converters and particulate filters.
So for these new CAFE rules, which were finalized on April 1,both agencies are effectively rating fuel economy. The EPA has mandated a fleet CO 2 average of grams per mile ( g/km).Author: Sam Abuelsamid.mirrors, sun roofs, and emissions equipment) rather than increasing fuel economy.4 In addition, a shift in 2 Klier, Thomas and Joshua Linn.
