Anyone else get approximately a 4 MPG difference with their top off? I know none of us bought a Jeep to save fuel, but going from 19-20 on the hwy to 15-16 is disheartening.

Not sure anyone buys a brick on wheels for fuel efficiency. I sure as heck didn’t. Not even sure I’ve checked MPG.

A 4MPG loss would not surprise me. The Wrangler is not very aerodynamic to begin with and topless, much less so. Especially at highway speeds. You're already dragging a large bubble of air behind you with a top on thanks to the "garden shed on wheels" shape. That becomes dragging a huge column of air behind you when topless.

I did a 600+ mile topless trip when mine was 6 months old and I didn't notice but a 1 or 2mpg drop to 17 mpg. I was driving interstate at 80mph compared to most highways being a tad lower.

I have a diesel and mine drops by about 2 mpg compared to when the hard top is on. Makes sense to me as air has more surfaces to grab into and slow you down.

Top and doors off 4dr went from 18mpg to 15-16. Yep.

Hard top off (but with a mesh sunshade on) I probably lose about 0.5-1 mpg on average. Nothing too significant for me. I could however see having the doors off adding a bit more drag and further reducing fuel mileage.

There is nothing wrong with being conscious of your efficiency, regardless of the fact it’s a wrangler. Don’t mind some of these comments.

4mpg is a little steep, I’d estimate mine to be about a 2-2.5mpg difference from my hardtop to no top. Modularity was a big consideration point when choosing the wrangler, so I still try to enjoy it when the UV index is low.
