Where These Numbers Come From
This page was built by Cedrick Reese from the U.S. EPA fuel economy dataset on fueleconomy.gov, which holds 47 ratings for the Acura RDX from 2007 to 2026. Each row in the table links to the matching EPA vehicle record, so you can check any figure against the source. Ratings from before 2008 use the EPA's revised estimates, which put older vehicles on the same scale as newer ones. When the EPA posts an updated file with new model years or corrected ratings, this page is rebuilt from it. The cost calculator uses the gas price you enter rather than a national average, so the result fits where you live.
Ratings on this page come from the EPA file downloaded on October 1, 2026.
