My 2021 JLURD is about two states away and steaming (I wish) towards Phoenix.
My window sticker reads: 21 City, 26 Highway, 23 combined. That's 2 MPG less combined than 2020s with highway taking a bigger hit (3 MPG) than city. Originally the theory was a 4.10 final drive ratio on the 2021s versus 3.73 on the 2020s, but one of the first 2021 diesels delivered has 3.73 ("just less than four axle turns when I completely spin a rear wheel").
So where did the 2 MPG go? I didn't order the diesel for economy, but it is a nice side benefit.
