49 U.S.C. § 32918

1. (a)In this section, the term “retrofit device” means any component, equipment, or other device—as determined under regulations of the Administrator of the Environmental Protection Agency. The term also includes a fuel additive for use in an automobile.
   1. (1)that is designed to be installed in or on an automobile (as an addition to, as a replacement for, or through alteration or modification of, any original component, equipment, or other device); and
   2. (2)that any manufacturer, dealer, or distributor of the device represents will provide higher fuel economy than would have resulted with the automobile as originally equipped,
2. (b)The Federal Trade Commission shall establish a program for systematically examining fuel economy representations made with respect to retrofit devices. Whenever the Commission has reason to believe that any representation may be inaccurate, the Commission shall request the Administrator to evaluate, in accordance with subsection (c) of this section, the retrofit device with respect to which the representation was made.
3. (c)
   1. (1)On application of any manufacturer of a retrofit device (or prototype of a retrofit device), on request of the Commission under subsection (b) of this section, or on the motion of the Administrator, the Administrator shall evaluate, in accordance with regulations prescribed under subsection (e) of this section, any retrofit device to determine whether the retrofit device increases fuel economy and to determine whether the representations, if any, made with respect to the retrofit device are accurate.
   2. (2)If under paragraph (1) of this subsection, the Administrator tests, or causes to be tested, any retrofit device on the application of a manufacturer of the device, the manufacturer shall supply, at the manufacturer’s expense, one or more samples of the device to the Administrator and shall be liable for the costs of testing incurred by the Administrator. The procedures for testing retrofit devices so supplied may include a requirement for preliminary testing by a qualified independent testing laboratory, at the expense of the manufacturer of the device.
4. (d)
   1. (1)The Administrator shall publish in the Federal Register a summary of the results of all tests conducted under this section, together with the Administrator’s conclusions as to—
      1. (A)the effect of any retrofit device on fuel economy;
      2. (B)the effect of the device on emissions of air pollutants; and
      3. (C)any other information the Administrator determines to be relevant in evaluating the device.
   2. (2)The summary and conclusions shall also be submitted to the Secretary of Transportation and the Commission.
5. (e)The Administrator shall prescribe regulations establishing—
   1. (1)testing and other procedures for evaluating the extent to which retrofit devices affect fuel economy and emissions of air pollutants; and
   2. (2)criteria for evaluating the accuracy of fuel economy representations made with respect to retrofit devices.
