Lexus GS Hybrid
This is a hybrid, not a plug-in: there is nothing to charge and one fuel economy figure, 31 MPG combined. The question worth answering is not what it returns but whether it returns enough more than the plain version of the same car to justify what the hybrid costs.

13 owners filed these through the EPA's own My MPG tool. That is a sample, not an average — read them as anecdotes. They are here because they are the only owner-reported figures in public federal data.

How this is worked out
Cost per mile is the gasoline price over the combined MPG, at the fuel price and mileage you enter. The comparison uses the best-rated trim of the non-hybrid version of the same car in the same year — comparing against its worst trim would flatter the hybrid.
Every figure comes from the U.S. EPA's public fuel economy data. We add no estimates of our own; a missing number shows as a dash rather than a guess.
Add your numbers
Federal data has at most a handful of owners per car and nothing at all on servicing. If you own one, send what you actually get. It goes on this page with the sample size next to it.
Your car's real number
Every figure on this page is an EPA lab rating. What your car actually does depends on your roads, your right foot, and its maintenance history. Carvico calculates your true MPG from your own fill-ups — kept completely private on your iPhone and iCloud.
