Default 2door vs 4door mpg

Looking to pick up a new flame red rubi and noticed that on the jeep site it says that the 2 door gets 19mpg and the 4door gets 21. Is that right?
Does the four door get better mileage? I understand that the aerodynamic curl over the upper foil could be better on the added length of the 4door but it should be offset by the added weight.

The 21 figure is based on a 2-wheel drive Unlimited. You can't get a 2WD 2-door anymore.

The 2-door and the 4-door get virtually the same gas mileage. A stripped down 2-door might squeeze out a couple MPGs more than a loaded 4-door.

The last two fill ups were 15.9 and 16.57 MPG. I drive back and forth to work into Baltimore every day. Some stop and go traffic. I also tend to cruise at about 70 on the main drag from Annapolis to Baltimore. I am dreading the 35s that will soon be installed, but I also can't wait! Can't be any worse than my Toyota Tundra and 35s - that thing drained gas like it had a hole in the tank.

.
which absolutely make no sense to me since the 4 doors is 200-300 lb heavier . Studies show that adding 100lb in a car increase gas mileage by about 2 percent, also the 2dr being smaller in size, the drag is less as well which again should account for better efficiency.... I just don't get it, but Chysler's physics don't add up.

I don't know who told you that, but you will get better mileage with a two door?

As far as I always heard the 2dr "can" get better mileage. I have a 2dr, CAI, cruise/speed control, back seat removed. I get 20-22 mpgs hwy.

I think this is the best answer to the original question so far.

When could you EVER get a 2wd 2dr? Pre-CJ?
