Status message

There are 2 Updates appearing in the Federal Register for 40 CFR 600. View below or at eCFR (GPOAccess)
§ 600.513-08 Gas Guzzler Tax.
(a) This section applies only to passenger automobiles sold after December 27, 1991, regardless of the model year of those vehicles. For alcohol dual fuel and natural gas dual fuel automobiles, the fuel economy while such automobiles are operated on gasoline will be used for Gas Guzzler Tax assessments.
(1) The provisions of this section do not apply to passenger automobiles exempted for Gas Guzzler Tax assessments by applicable Federal law and regulations. However, the manufacturer of an exempted passenger automobile may, in its discretion, label such vehicles in accordance with the provisions of this section.
(2) For 1991 and later model year passenger automobiles, the combined FTP/HFET-based model type fuel economy value determined in § 600.208 used for Gas Guzzler Tax assessments shall be calculated in accordance with the following equation, rounded to the nearest 0.1 mpg:
FEadj = FE[((0.55 × ag × c) (0.45 × c) (0.5556 × ag) 0.4487)/((0.55 × ag) 0.45)] IWg
Where:
FEadj = Fuel economy value to be used for determination of gas guzzler tax assessment rounded to the nearest 0.1 mpg.
FE = Combined model type fuel economy calculated in accordance with § 600.208, rounded to the nearest 0.0001 mpg.
ag = Model type highway fuel economy, calculated in accordance with § 600.208, rounded to the nearest 0.0001 mpg divided by the model type city fuel economy calculated in accordance with § 600.208, rounded to the nearest 0.0001 mpg. The quotient shall be rounded to 4 decimal places.
c = gas guzzler adjustment factor = 1.300 × 10−3 for the 1986 and later model years.
IWg = (9.2917 × 10−3 × SF3IWCGFE3IWCG) − (3.5123 × 10-3× SF4ETWG × FE4IWCG).
Note:
Any calculated value of IW less than zero shall be set equal to zero.
SF3IWCG = The 3000 lb. inertia weight class sales in the model type divided by the total model type sales; the quotient shall be rounded to 4 decimal places.
SF4ETWG = The 4000 lb. equivalent test weight sales in the model type divided by the total model type sales, the quotient shall be rounded to 4 decimal places.
FE3IWCG = The 3000 lb. inertial weight class base level combined fuel economy used to calculate the model type fuel economy rounded to the nearest 0.0001 mpg.
FE4IWCG = The 4000 lb. inertial weight class base level combined fuel economy used to calculate the model type fuel economy rounded to the nearest 0.001 mpg.
(b)
(1) For passenger automobiles sold after December 31, 1990, with a combined FTP/HFET-based model type fuel economy value of less than 22.5 mpg (as determined in § 600.208), calculated in accordance with paragraph (a)(2) of this section and rounded to the nearest 0.1 mpg, each vehicle fuel economy label shall include a Gas Guzzler Tax statement pursuant to 49 U.S.C. 32908(b)(1)(E). The tax amount stated shall be as specified in paragraph (b)(2) of this section.
(2) For passenger automobiles with a combined general label model type fuel economy value of:
At least * * * but less than * * * the Gas Guzzler Tax statement shall show a tax of * * *
(i) 22.5 $0
(ii) 21.5 22.5 $1,000
(iii) 20.5 21.5 $1,300
(iv) 19.5 20.5 $1,700
(v) 18.5 19.5 $2,100
(vi) 17.5 18.5 $2,600
(vii) 16.5 17.5 $3,000
(viii) 15.5 16.5 $3,700
(ix) 14.5 15.5 $4,500
(x) 13.5 14.5 $5,400
(xi) 12.5 13.5 $6,400
(xii) — 12.5 $7,700
