G80 MPG Over the Years
Each bar shows the range of combined MPG across every G80 configuration the EPA rated that year, from the thirstiest version to the most efficient. Hover or tap a year to see the numbers. Electric versions are rated in MPGe, so they're left out of the chart and listed in the table instead.

Why doesn't my G80 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
Cedrick Reese built this page from the EPA fuel economy file published on fueleconomy.gov. It has 43 ratings for the G80 from 2017 to 2027, and every one of them is shown in the table. Each row in the table links to the matching EPA vehicle record, so you can check any figure against the source. Electric versions are rated in MPGe, the EPA's miles-per-gallon equivalent, and the table also shows their official range. 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 or electricity 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.
