The 2021 Ram 1500 TRX's Gas Mileage Is Hilariously Awful - RoadandTrack.com

The official fuel economy still isn't on the EPA's fuel economy site.

But as we noted in our first drive review, Ram already has the official numbers: 10 miles per gallon in the city and 14 on the highway for a combined score of 12 mpg.

For reference, the 450-hp Ford F-150 Raptor gets a score of 15 mpg city and 18 mpg highway for a combined figure of 16 mpg.

So a truck that gets 5 mpg will cost twice as much to fuel as a truck that gets 10 mpg, but a 25-mpg truck will only save you 25 percent compared to a 20-mpg truck.
