I review the 2024 Ford f150 with the 5L coyote V8 engine and compare 3.73 gears to the standard 3.31 gears when it comes to Fuel Economy performance. I compare fuel economy (MPG) and to my surprise it seems like the 3.73 gears were more fuel efficient which to me signifies that gearing does not make that much of an impact on unloaded ford f150 trucks.

I was very excited to test out if Gearing in a truck really makes a real world difference in fuel economy. Both these 2024 Ford F150 trucks have the 5L coyote V8 in them with the 10 speed transmission. 4x4 trucks with crew cab so they are basically identical trucks. the only difference is the gearing.
I take these trucks on my 85 fuel economy loop to determine if gearing does indeed affect the fuel economy.
in theory the 3.31 gears should result in better fuel economy whereas the 3.73 gears do give better acceleration but this results in the engine rotating faster thus drinking more fuel.
