{"data":{"id":"us/40-cfr-600.304-12","jurisdiction":"us","citation":"40 CFR 600.304-12","heading":"-12 Fuel economy label—special requirements for hydrogen fuel cell vehicles.","body":"Fuel economy labels for hydrogen fuel cell vehicles must meet the specifications described in § 600.302, with the following modifications:\n(a) Include the following statement instead of the statement specified in § 600.302-12(b)(4): “Actual results will vary for many reasons, including driving conditions and how you drive and maintain your vehicle. The average new vehicle gets a MPG and costs $b to fuel over 5 years. Cost estimates are based on c miles per year at $d per kilogram of hydrogen. Vehicle emissions are a significant cause of global warming and smog.” For a, b, c, and d, insert the appropriate values established by EPA.\n(b) Include the following elements instead of the information identified in § 600.302-12(c)(1):\n(1) The heading “Fuel Economy” near the top left corner of the field.\n(2) The combined fuel economy value as determined in § 600.311 below the heading. Include the expression “combined city/hwy” below this number.\n(3) The logo specified in § 600.302-12(b)(3)(ii) to the left of the combined fuel economy value.\n(4) The units identifier and specific fuel economy values to the right of the combined fuel economy value as follows:\n(i) Include the term “MPGe” in the upper portion of the designated space.\n(ii) Include the city fuel economy value determined in § 600.311 in the lower left portion of the designated space. Include the expression “city” below this number.\n(iii) Include the highway fuel economy value determined in § 600.311 in the lower right portion of the designated space. Include the expression “highway” below this number.\n(5) The fuel consumption rate determined in § 600.311, to the right of the fuel economy information. Include the expression “kg H2 per 100 miles” below the numerical value.\n(6) The sub-heading “Driving Range” below the combined fuel economy value. Below this sub-heading, insert a horizontal range bar nominally 80 mm long to show how far the vehicle can drive when fully fueled. Include a vehicle logo at the right end of the range bar. Include the following left-justified expression inside the range bar: “When fully fueled, vehicle can travel about * * *”. Below the right end of the range bar, include the expression “x miles”; complete the expression by identifying the appropriate value for total driving range from § 600.311. Include numbers below the bar showing the scale, with numbers starting at 0 and increasing in equal increments. Use good engineering judgment to divide the range bar into four, five, or six increments.","path":["Title 40—Protection of Environment","CHAPTER I—ENVIRONMENTAL PROTECTION AGENCY","SUBCHAPTER Q—ENERGY POLICY","PART 600—FUEL ECONOMY AND GREENHOUSE GAS EXHAUST EMISSIONS OF MOTOR VEHICLES","Subpart D—Fuel Economy Labeling"],"source_url":"https://www.ecfr.gov/api/versioner/v1/full/2026-08-25/title-40.xml","current_through":"2026-08-25","vintage":"","retrieved_at":"2026-08-27T02:26:04Z","sha256":"2d3d0b98d584996b667585b1b0c2d66d3f2ea2b90932a7779e0170a6efc32a66","source_id":"us-cfr","stale":true,"prev":"us/40-cfr-600.303-12","next":"us/40-cfr-600.306-12"},"notice":"GroundRules: Original legal text.
