Assume a hypothetical manufacturer (Manufacturer X) produces a fleet of light trucks in MY 2012 as follows:
Appendix A-Table I
Model type | Description | Actual measured fuel economy (mpg) | Volume | |||
Group | Carline name | Basic engine (L) | Transmission class | |||
1 | Pickup A 2WD | 4 | A5 | Reg cab, MB | 27.1 | 800 |
2 | Pickup B 2WD | 4 | M5 | Reg cab, MB | 27.6 | 200 |
3 | Pickup C 2WD | 4.5 | A5 | Reg cab, LB | 23.9 | 300 |
4 | Pickup C 2WD | 4 | M5 | Ext cab, MB | 23.7 | 400 |
5 | Pickup C 4WD | 4.5 | A5 | Crew cab, SB | 23.5 | 400 |
6 | Pickup D 2WD | 4.5 | A6 | Crew cab, SB | 23.6 | 400 |
7 | Pickup E 2WD | 5 | A6 | Ext cab, LB | 22.7 | 500 |
8 | Pickup E 2WD | 5 | A6 | Crew cab, MB | 22.5 | 500 |
9 | Pickup F 2WD | 4.5 | A5 | Reg cab, LB | 22.5 | 1,600 |
10 | Pickup F 4WD | 4.5 | A5 | Ext cab, MB | 22.3 | 800 |
11 | Pickup F 4WD | 4.5 | A5 | Crew cab, SB | 22.2 | 800 |
Total | 6,700 |
Note to Table I to this appendix: Manufacturer X's required fleet average fuel economy standard level would first be calculated by determining the fuel economy targets applicable to each unique model type and footprint combination for model type groups 1-11 as illustrated in Table II to this appendix.
Manufacturer X calculates a fuel economy target standard for each unique model type and footprint combination.
Appendix A-Table II

Total | 6,700 |
Note to Table II to this appendix: With the appropriate fuel economy targets determined for each unique model type and footprint combination, Manufacturer X's required fleet average fuel economy standard would be calculated as illustrated in Figure 1 to this appendix:
49 C.F.R. §A to Part 533
Note to Figure 2 to this appendix: Since the actual fleet average fuel economy performance of Manufacturer X's fleet is 23.3 mpg, as compared to its required fleet fuel economy standard of 23.7 mpg, Manufacturer X did not comply with the CAFE standard for MY 2012 as set forth in § 533.5(i) .
