No, the 54.5 mpg goal by 2025 was from the Obama administration. The Trump administration nixed that and set the fleet fuel economy target to 37 mpg. Several auto manufacturers actually came out against lowering the standard because it would put them in a worse place for global markets and they've already made big investments in alternative drivetrains. California decided that they did not want to lower their standard to follow the Trump standard and 4 manufacturers made an agreement to a CA standard that was a bit less aggressive than the original Obama fuel economy target. Then the Trump administration sued those 4 car companies, and moved to rescind California's exception under the Clean Air Act that allowed them to set their own emissions standards.
