Does all-wheel drive hurt G90 fuel economy?

Why doesn't my G90 match the EPA numbers?
EPA ratings come from standardized lab tests so every car is measured the same way. Your results depend on speed, climate, idling, cargo, tire pressure and upkeep. The ratings are best for comparing one car against another. To track your own numbers, try the MPG calculator.

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 32 ratings for the Genesis G90 from 2017 to 2026. Each row in the table links to the matching EPA vehicle record, so you can check any figure against the source. The page is rebuilt whenever the EPA publishes an updated file, which picks up new model years and any rating corrections. 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.
