I took my new 2023 ecodiesel for a highway trip to test mpg. Because I have the 3.92 axle, I anticipated less than the window sticker rating of 29 mpg. After the 100 mile round trip, the vehicle display showed that I obtained 34 mpg. I drove at highway speeds (I averaged 65 mph , but up to 75 mph to stay with traffic). When I later filled up after two weeks of city/highway combined, I calculated 28 mpg, which exactly matched the mpg that the vehicle showed.
Based on my experience with my previous Hemi Rebel, the 3.92 axle resulted in a 2 mpg drop in mpg over that stated on the window sticker. There was no mpg loss in the Rebel with the 3.92 axle in town or towing, (it just ran in a higher transmission gear to compensate for the axle ratio). For those experiencing lower mpg than stated on the window sticker, the biggest factor is speed. These beasts are not very aerodynamic and there is a lot of wind resistance at 80 mph. I will post again after more experience with the ecodiesel and when I start towing my travel trailer again.
