Where These Numbers Come From

This Cadillac page was put together by Cedrick Reese from the EPA fuel economy file published on fueleconomy.gov. The model list and every rating on it are generated from that file, so nothing is typed in by hand. Each model page shows the individual EPA records behind these numbers, with a link to each one. When the EPA posts an updated file, this page and the Cadillac model pages are rebuilt from it.

Ratings on this page come from the EPA file downloaded on October 1, 2026.
