CAFE footprint requirements are set up such that a vehicle with a larger footprint has a lower fuel economy requirement than a vehicle with a smaller footprint. For example, the fuel economy target for the 2012 Honda Fit with a footprint of is , equivalent to a published fuel economy of (see #Calculations of MPG overestimated for information regarding the difference), and a Ford F-150 with its footprint of has a fuel economy target of , i.e., published. Individual vehicles do not have to meet their fuel economy targets; CAFE compliance is enforced at the fleet level. CAFE 2016 target fuel economy of 34.0 MPG (44 sq. ft. footprint) compares to 2012 advanced vehicle performance of Prius hybrid on the compliance test cycles: 70.7 MPG, Plug-in Prius hybrid: 69.8 MPGe and LEAF electric vehicle: 141.7 MPGe. The compliance fuel economy of plug-in electric vehicles such as the Plug-in Prius or LEAF is complicated by accounting for the energy used in generating electricity. In 2012, the LEAF's compliance fuel consumption was considered to be 0 gal/mi, or infinite fuel economy, as it uses no liquid fuel on board, and that of the Plug-in Prius was also adjusted for the portion of vehicle energy use originating from the electric grid.
