[Code of Federal Regulations] [Title 16, Volume 1] [Revised as of January 1, 2006] From the U.S. Government Printing Office via GPO Access [CITE: 16CFR309.22] [Page 362-363] TITLE 16--COMMERCIAL PRACTICES CHAPTER I--FEDERAL TRADE COMMISSION PART 309_LABELING REQUIREMENTS FOR ALTERNATIVE FUELS AND ALTERNATIVE FUELED VEHICLES--Table of Contents Subpart C_Requirements for Alternative Fueled Vehicles Sec. 309.22 Determining estimated cruising range. (a) Dedicated vehicles. (1) Estimated cruising range values for dedicated vehicles required to comply with the provisions of 40 CFR part 600 are to be calculated in accordance with the following: (i) The lower range value shall be determined by multiplying the vehicle's estimated city fuel-economy by its fuel tank capacity, then rounding to the next lower integer value. (ii) The upper range value shall be determined by multiplying the vehicle's estimated highway fuel-economy by its fuel tank capacity, then rounding to the next higher integer value. (2) Estimated cruising range for an EV is the actual vehicle range determined in accordance with test methods set forth in Society of Automotive Engineers (``SAE'') Surface Vehicle Recommended Practice SAE J1634-1993-05-20, ``Electric Vehicle Energy Consumption and Range Test Procedure.'' This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51. Copies of SAE J1634-1993-05-20 may be obtained from the Society of Automotive Engineers, 400 Commonwealth Drive, Warrendale, PA, 15096-0001, or may be inspected at the Federal Trade Commission, Public Reference Room, room 130, 600 Pennsylvania Avenue, NW, Washington, DC, or at the National Archives and Records [[Page 363]] Administration (NARA).

(3) To determine the estimated cruising range values for dedicated vehicles not required to comply with the provisions of 40 CFR part 600 (other than electric vehicles), you must possess a reasonable basis, consisting of competent and reliable evidence that substantiates the minimum and maximum number of miles the vehicle will travel between refuelings or rechargings that is claimed. (b) Dual-fueled vehicles. (1) Estimated cruising range values for dual-fueled vehicles required to comply with the provisions of 40 CFR part 600 are to be calculated in accordance with the following: (i) The lower range value for the vehicle while operating exclusively on alternative fuel shall be determined by multiplying the vehicle's estimated city fuel-economy by its alternative-fuel tank capacity, then rounding to the next lower integer value. (ii) The upper range value for the vehicle while operating exclusively on alternative fuel shall be determined by multiplying the vehicle's estimated highway fuel-economy by its alternative-fuel tank capacity, then rounding to the next higher integer value. (iii) The lower range value for the vehicle while operating exclusively on conventional fuel shall be determined by multiplying the vehicle's estimated city fuel-economy by its conventional-fuel tank capacity, then rounding to the next lower integer value. (iv) The upper range value for the vehicle while operating exclusively on conventional fuel shall be determined by multiplying the vehicle's estimated highway fuel-economy by its conventional-fuel tank capacity, then rounding to the next higher integer value. (2) [Reserved] (3) To determine the estimated cruising range values for dual-fueled vehicles not required to comply with the provisions of 40 CFR part 600 (other than electric vehicles), you must possess a reasonable basis, consisting of competent and reliable evidence, of: (i) The minimum and maximum number of miles the vehicle will travel between refuelings or rechargings when operated exclusively on alternative fuel, and (ii) The minimum and maximum number of miles the vehicle will travel between refuelings or rechargings when operated exclusively on conventional fuel.
