§ 600.209-85 Calculation of fuel economy values for labeling.
(a) For the purposes of calculating the city model type fuel economy value for labeling the manufacturer shall:
(1) For general labels multiply the city model type fuel economy value determined in § 600.207(b), by 0.90, rounding the product to the nearest whole mpg, or

(b) For the purposes of calculating the highway model type fuel economy value for labeling the manufacturer shall:
(1) For general labels multiply the highway model type fuel economy value determined in § 600.207(b) by 0.78, rounding the product to the nearest whole mpg, or
(2) For specific labels multiply the highway fuel economy value determined in § 600.206(a)(iii) by 0.78.
(c) If the resulting city value determined in paragraph (a) of this section exceeds the resulting highway value determined in paragraph (b) of this section, the city value will be set equal to the highway value.

(1) The combined fuel economy for a model type, to be used in determining annual fuel costs under § 600.308(c), is determine (except as provided for in paragraph (d)(2) of this section), by harmonically averaging the unrounded city and highway values, determined in § 209 (a) and (b), weighted 0.55 and 0.45 respectively, and rounded to the nearest whole mpg. (An example of this calculation procedure appears in appendix II of this part).
