Not true. CAFE was amended in the late 2000s to provide more fuel restrictions for smaller cars while keeping the same fuel restrictions for bigger cars. The result is bigger cars being made.
What isn't true? Nothing you said, even if it was true (it's not) contradicts anything in the grandparent post.

No, it wasn’t. The footprint model within the passenger car class did differentiate by size, but it didn’t provide more restrictions for smaller cars while keeping larger cars the same.
