Truth be told, your car won't have to get 54 mpg. To reach that magic Corporate Average Fuel Economy level (CAFE) 40 mpg. Why? Because fuel economy window stickers and the fleet average are calculated in two different ways. There's been lots written about this, in places like Edmunds and Scientific American. But here's the short version:
CAFE mpg is based on a set of tests — city cycle and highway cycle — that were put in place back when the government began requiring car company fleets to achieve an average level. But window sticker fuel economy is based on a series of five tests, including hot weather, cold weather, air conditioning use, and driving at higher speeds. I went to an EPA press conference at their lab in Ann Arbor a few years ago where they painstakingly explained this all to us. (It reminded me why I didn't get a master's degree in science.)
Window sticker fuel economy has always been lower than the overall CAFE standard. According to Edmunds, the 34.1 mpg CAFE target for 2016 is actually equal to only 26 mpg on a window sticker. And, it says the 2025 standard is probably more like 36 mpg.
