Who’s the most efficient automaker of them all? According to TrueCar’s projections for May, Smart, MINI, Hyundai, VW and Scion top the list for sales-weighted fleet fuel economy. Meanwhile, the industry average of 22.4 MPG might not sound like much, but when you convert it to the “unadjusted” numbers used for CAFE, that 22 MP turns into about 28 MPG. Considering the 2015 CAFE standard is 35.5 MPG between cars and trucks, that average shows the industry to be fairly well on-track to comply with the initial CAFE ramp-up. In fact, since 35.5. MPG CAFE equals about 27 MPG EPA, it seems that the top three brands on this list (Smart, MINI, Hyundai) can pretty much twiddle their thumbs between now and 2015, as they’re practically in compliance with the 35.5 MPG standard already.
