The EPA Federal Test Procedure , commonly known as FTP-75 for the city driving cycle , are a series of tests defined by the US Environmental Protection Agency (EPA) to measure tailpipe emissions and fuel economy of passenger cars (excluding light trucks and heavy-duty vehicles).
30-519: The testing was mandated by the Energy Tax Act of 1978 in order to determine the rate of the guzzler tax that applies for the sales of new cars. The current procedure has been updated in 2008 and includes four tests: city driving (the FTP-75 proper), highway driving (HWFET), aggressive driving (SFTP US06), and optional air conditioning test (SFTP SC03). The Urban Dynamometer Driving Schedule
60-673: A slip law and in the United States Statutes at Large after receiving the act. Thereafter, the changes are published in the United States Code . Through the process of judicial review , an act of Congress that violates the Constitution may be declared unconstitutional by the courts. A judicial declaration that an act of Congress is unconstitutional does not remove the act from the Statutes at Large or
90-451: A duration of 596 seconds. A cold temperature cycle uses the same parameters as the current city loop, except that ambient temperature is set to 20 °F (−7 °C). EPA tests for fuel economy do not include electrical load tests beyond climate control, which may account for some of the discrepancy between EPA and real world fuel-efficiency. A 200 W electrical load can produce a 0.94 mpg (0.4 km/L) reduction in efficiency on
120-427: A duration of 596 seconds. The SC03 Supplemental Federal Test Procedure (SFTP) has been introduced to represent the engine load and emissions associated with the use of air conditioning units in vehicles certified over the FTP-75 test cycle. SFTO SC03 is the air conditioning test, which raises ambient temperatures to 95 °F (35 °C), and puts the vehicle's climate control system to use. Lasting 9.9 minutes,
150-479: A top speed of 60 mph (97 km/h) over a 10-mile (16 km) distance. The following are some characteristic parameters of the cycle: Before the 5-cycle fuel economy estimates were introduced in 2006 the measurements were adjusted downward by 10% (city) and 22% (highway) to more accurately reflect real-world results. In 2007, the EPA added three new Supplemental Federal Test Procedure (SFTP) tests that combine
180-530: Is 56.7 mph (91.2 km/h) and the average speed is 19.6 mph (31.5 km/h). The cycle has two phases: a "cold start" phase of 505 seconds over a projected distance of 3.59 mi at 25.6 mph average speed, and a "transient phase" of 864 seconds, for a total duration of 1369 seconds. The "city" driving program of the EPA Federal Test Procedure is identical to the UDDS plus
210-563: Is a statute enacted by the United States Congress . Acts may apply only to individual entities (called private laws ), or to the general public ( public laws ). For a bill to become an act, the text must pass through both houses with a majority, then be either signed into law by the president of the United States , be left unsigned for ten days (excluding Sundays) while Congress remains in session, or, if vetoed by
240-610: Is a high speed/quick acceleration loop that lasts 10 minutes, covers 8 miles (13 km), averages 48 mph (77 km/h) and reaches a top speed of 80 mph (130 km/h). Four stops are included, and brisk acceleration maximizes at a rate of 8.46 mph (13.62 km/h) per second. The engine begins warm and air conditioning is not used. Ambient temperature varies between 68 °F (20 °C) to 86 °F (30 °C). The cycle represents an 8.01 mile (12.8 km) route with an average speed of 48.4 miles/h (77.9 km/h), maximum speed 80.3 miles/h (129.2 km/h), and
270-654: Is a mandated dynamometer test on tailpipe emissions of a car that represents city driving conditions. It is defined in 40 CFR 86.I . It is also known as FTP-72 or LA-4 , and it is also used in Sweden as the A10 or CVS (Constant Volume Sampler) cycle and in Australia as the ADR 27 (Australian Design Rules) cycle. The cycle simulates an urban route of 7.5 mi (12.07 km) with frequent stops. The maximum speed
300-489: Is collected by the Internal Revenue Service (IRS) and normally paid by the manufacturer or importer. The following chart shows the current tax for various levels of MPG that have been in effect since January 1, 1991. The combined fuel economy MPG value (55% city, 45% highway) is used to determine tax liability. The MPG value is also adjusted slightly to account for differences in test procedures made since
330-592: Is equal to 30% of the cost of the equipment up to $ 2000, as well as 20% of costs greater than $ 2000, up to a maximum of $ 10,000. There were also tax credits to businesses for renewable energy equipment, amounting to a maximum of 25% of the cost of the equipment. The renewable energy credits of this law were increased by the Crude Oil Windfall Profits Tax Act of 1980. The Act also created the Gas Guzzler Tax which applies to
SECTION 10
#1732780545904360-580: Is made by the third method, the presiding officer of the house that last reconsidered the act promulgates it. Under the United States Constitution , if the president does not return a bill or resolution to Congress with objections before the time limit expires, then the bill automatically becomes an act; however, if the Congress is adjourned at the end of this period, then the bill dies and cannot be reconsidered (see pocket veto ). If
390-410: Is sometimes used in informal speech to indicate something for which getting permission is burdensome. For example, "It takes an act of Congress to get a building permit in this town." An act adopted by simple majorities in both houses of Congress is promulgated , or given the force of law, in one of the following ways: The president promulgates acts of Congress made by the first two methods. If an act
420-739: The Cherokee XJ and the S-10 Blazer (in 1984). By the time Ford introduced the Explorer , the SUV had become the common man's luxury vehicle and Ford capitalized on this using extensive cross-marketing, most notably with Northwest clothier Eddie Bauer . Critics of the Gas Guzzler Tax contend that the increased fuel economy of the US passenger car fleet observed since 1978 must be considered in
450-429: The 3.6-mile (5.8 km) loop averages 22 mph (35 km/h) and maximizes at a rate of 54.8 mph (88.2 km/h). Five stops are included, idling occurs 19 percent of the time and acceleration of 5.1 mph/sec is achieved. Engine temperatures begin warm. The cycle represents a 3.6 mile (5.8 km) route with an average speed of 21.6 miles/h (34.8 km/h), maximum speed 54.8 miles/h (88.2 km/h), and
480-667: The FTP 75 cycle test. Energy Tax Act The Energy Tax Act ( Pub. L. 95–618 , 92 Stat. 3174 , enacted November 9, 1978) is a law passed by the U.S. Congress as part of the National Energy Act . The objective of this law was to shift from oil and gas supply toward energy conservation ; thus, to promote fuel efficiency and renewable energy through taxes and tax credits . This law gave an income tax credit to private residents who use solar , wind , or geothermal sources of energy. The credit
510-516: The base year, but it is not adjusted for in-use short fall. The unadjusted combined MPG of a vehicle can be approximated from the city and highway values provided in the Fuel Economy Guide by the following equation : Since this is an approximate calculation, the actual gas guzzler tax may be off by one tax bracket. We can then find out how much penalty, p t {\displaystyle {\mathit {p_{t}}}} ,
540-548: The context of the increased market share of mid-size and full-size SUVs. Many consumers' stated reasons for SUV purchase (comfort, interior room, and a perception of safety based on the vehicle's size) also apply to the now-obsolete American full-size car as produced from the 1920s through the 70s; critics contend that the dominance of the modern SUV is a direct result of the Gas Guzzler Tax, which could have applied to all consumer vehicles but does not. Act of Congress#Public law, private law, designation An act of Congress
570-446: The current city and highway cycles to reflect real world fuel economy more accurately,. Estimates are available for vehicles back to the 1985 model year. The US06 Supplemental Federal Test Procedure (SFTP) was developed to address the shortcomings with the FTP-75 test cycle in the representation of aggressive, high speed and/or high acceleration driving behavior, rapid speed fluctuations, and driving behavior following startup. SFTP US06
600-410: The first 505 seconds of an additional UDDS cycle. Then the characteristics of the cycle are: The procedure is updated by adding the "hot start" cycle that repeats the "cold start" cycle of the beginning of the UDDS cycle. The average speed is thus different but the maximum speed remains the same as in the UDDS. The weighting factors are 0.43 for the cold start and transient phases together and 0.57 for
630-665: The hot start phase. Though it was originally created as a reference point for fossil fuelled vehicles, the UDDS and thus the FTP-75, are also used to estimate the range in distance travelled by an electric vehicle in a single charge. It is alleged that, similarly than in the NEDC, some automakers overinflate tyres, adjusting or disconnecting brakes to reduce friction, and taping cracks between body panels and windows to reduce air resistance, some go as far as removing wing mirrors, to inflate measured fuel economy and lower measured carbon emission. In addition, it has been brought to attention that
SECTION 20
#1732780545904660-491: The increase in sales and production of fuel efficient vehicles doesn't just encourage people to drive more. The Gas Guzzler Tax led to the successive downsizing of most major American passenger autos, and the combination of the tax and late-'70s/early-'80s economic woes effectively killed the American full-size car as it had been known up to that point. It only took one product cycle before the first modern SUVs were introduced,
690-590: The manufacturer has to pay for that particular vehicle by using the following equation. p i {\displaystyle {\mathit {p_{i}}}} needs to be looked up on the table above and q i {\displaystyle {\mathit {q_{i}}}} is the numbers of cars that are found to be under the set Gas Guzzler standard, p t = ∑ i p i q i {\displaystyle p_{t}=\sum _{i}{p_{i}q_{i}}\,} Gas guzzler tax creates incentive to meet
720-422: The minimum MPG requirement by manufacturer. Due to elimination of vehicles that are below minimum MPG which is 22.5 MPG, vehicle sales have decreased approximately 0.5 percent. However, sales revenues increase by a greater amount due to the added value in vehicles making greater use of fuel economy technology. Manufacturers benefit from the increase in price of products. However, the fuel sector may lose revenue if
750-445: The president rejects a bill or resolution while the Congress is in session, a two-thirds vote of both houses of Congress is needed for reconsideration to be successful. Promulgation in the sense of publishing and proclaiming the law is accomplished by the president, or the relevant presiding officer in the case of an overridden veto, delivering the act to the archivist of the United States . The archivist provides for its publication as
780-416: The president, receive a congressional override from 2 ⁄ 3 of both houses. In the United States, acts of Congress are designated as either public laws , relating to the general public, or private laws , relating to specific institutions or individuals. Since 1957, all Acts of Congress have been designated as "Public Law X–Y" or "Private Law X–Y", where X is the number of the Congress and Y refers to
810-422: The relative height of the simulated wind fan with respect to the vehicle could alter the performance of aftertreatment systems due to changes in temperature and, consequently, modify the pollutant emissions values. The "highway" program or Highway Fuel Economy Driving Schedule (HWFET) is defined in 40 CFR 600.I . It uses a warmed-up engine and makes no stops, averaging 48 mph (77 km/h) with
840-582: The sales of vehicles with official EPA-estimated gas mileage below certain specified levels. In 1980, the tax was $ 200 for a fuel efficiency of 14 to 15 miles per gallon , and was increased to $ 1800 in 1985. In 1980, the tax was $ 550 for fuel efficiencies of 13 mpg and below, and was changed in 1986 to $ 3,850 for ratings below 12.5 mpg. The Gas Guzzler Tax applies only to passenger cars. Trucks, sport utility vehicles (SUV), and minivans are not covered because these vehicle types were not widely available in 1978 and were rarely used for non-commercial purposes. The tax
870-408: The sequential order of the bill (when it was enacted). For example, P. L. 111–5 ( American Recovery and Reinvestment Act of 2009 ) was the fifth enacted public law of the 111th United States Congress . Public laws are also often abbreviated as Pub. L. No. X–Y. When the legislation of those two kinds are proposed, it is called public bill and private bill respectively. The word "act", as used in
900-488: The term "act of Congress", is a common, not a proper noun . The capitalization of the word "act" (especially when used standing alone to refer to an act mentioned earlier by its full name) is deprecated by some dictionaries and usage authorities. However, the Bluebook requires "Act" to be capitalized when referring to a specific legislative act. The United States Code capitalizes "act". The term "act of Congress"
