Title 49 › SUBTITLE VI — MOTOR VEHICLE AND DRIVER PROGRAMS › PART C — INFORMATION, STANDARDS, AND REQUIREMENTS › CHAPTER 329 — AUTOMOBILE FUEL ECONOMY › § 32908
Carmakers must put a fuel-economy label in a clear spot on every new car, and dealers must keep that label on the car. The label must show the car’s fuel economy, an estimate of yearly fuel cost, how that fuel economy compares to similar cars, a note that a comparison booklet is available from the dealer, the amount of the automobile fuel-efficiency tax under Internal Revenue Code section 4064, and any other related information the EPA requires. The EPA may let makers use the label from the Automobile Information Disclosure Act instead and may allow special timing for the tax statement. For cars made after model year 1992 that run only on alternative fuel, the label’s fuel-economy number is the measured alternative-fuel economy multiplied by 0.15. Cars that can run on two fuels must show their gasoline or diesel economy, be labeled as dual-fuel, list the fuels, and point buyers to extra information from the Secretary of Energy. The EPA must prepare a simple booklet with fuel-economy and yearly cost figures for each model year and may show regional cost differences. For dual-fuel cars made after model year 1992, the booklet must compare efficiency, cost, and driving range on gasoline or diesel versus alternative fuel, give miles-per-gallon on alternative fuel, and explain changes for fuel mixtures. The Secretary of Energy will publish and distribute the booklet, and EPA rules must require dealers to give it to buyers. Stating fuel economy does not create a warranty. Breaking the label rules is treated as a violation of the Automobile Information Disclosure Act and as an unfair or deceptive trade practice under the FTC Act (with certain exceptions). The EPA must consult the FTC and the Transportation and Energy Secretaries. The EPA Administrator must develop performance criteria within 18 months after the Ten-in-Ten Fuel Economy Act, and the Secretary of Transportation must issue a final rule under this part within 42 months of that Act.
