0 to 60 in 4.3 seconds with 35" tires & 93 octane fuel.
All stock performance parts ;)
Ok ok, it's not a diesel...
I am glad others are interested in their 0 to 60 times!!!
I knew it was only a matter of time before a 6.4 jumped in....... so for +30K your beating us by 1.35s. But really, 4.3 seconds is respectable for any modern sports car. It would be interesting to see the short list of what can beat that in stock form. Are you running the XR package with 4.56 gears?

Now to shift the conversation in my favor, can you get 29mpg on road trips?

wew, take her easy tiger 🐅

*Nope, not the XR, just your basic 2021 392, the XR wasn't offered when I placed my order back then. I do have a 2023 on order now with the XR package but I will cancel that IF jeep comes out with a 20th anniversary rubicon (which may have 4.88 gearing).

* You are correct, 4.3 seconds is respectable for any modern sports car...

*... leading me to this. YES! 30k is absolutely worth it. More specifically, coming up to that second stop light and you look over at the dude pulling up in his Charger in a close second (but still second) in disbelief as he's trying to fathom what in the Wrangle just happened. (dad joke)

*No, I certainly do not get 29mpg and you know that, especially when I'm hauling my 4,000lbs camper trailer over the hills with the cruise set at 80mph. But again, referencing my last bullet, those stop light expressions are absolutely priceless and nobody should spend 30k more on anything if they complain about gas prices.

All due respect, I wasn't trying to steal your 'favor'. I actually went to my dealership to buy a diesel JL (back in 2020) because I tow trailers and wanted the torque. It was then that I was informed that a 392 was supposed to come out.
I love all Jeeps to include yours :) P.S. ALL JEEPERS get the wave from me!!!

My first was a 1984 CJ7 with a whipped 2.5 four banger. 0-60 was a "if you're lucky" conversation.

all the torque off idle is what’s important with the Jeep. Only engine that makes that power without having to open the throttle is the diesel. The only video I seen of the 392 was in another post at 5000 altitude and it was 6.8 0-60 lol so the 4.3 seconds must have been below sea level, on a 15 percent grade going down hill and a rolling start thats not really 0-60😂🤣.

This reminds me of when the Hellcat came out. Dodge claimed a 9.6 second quarter mile time, while actual owners were having trouble breaking out of the high 11s.

I especially liked the wait until full dark to maximize power with cooler air and use of a prepared surface - a little disingenuous.

All of that said, 4.5 seconds does not seem unreasonable, but it sounds like owners are finding otherwise.

I wasn't complaining, my last two rides got about 15 on a good day. I was just using the only advantage we have over the 6.4 to my favor.

I had a CJ5 with the AMC304 for a very short time. Couldn't get clear title so I gave it back (that's a different story and different time- from the 80's) but that was so much fun!

I don't consider Mustangs, chargers, etc sports cars with their size and weight, most modern sports cars are around the 3.2- 3.5 second range 0-60 range in stock form and tuning gets you below that....

Are y’all doing anything special? Is there a sport mode or something I am missing (not tuned)? I bought my wife a 21 Willy 3.6 and liked it so much I bought myself a 2022 Jlurd because I wanted the torque knowing that I was going straight to 37’s. I don’t really notice the torque on the diesel except for when I’m on the highway in 8th gear in conditions that would make my wife’s jeep down shift. Hers definitely feels faster off the line with obviously no turbo lag. I definitely don’t feel like I would be able to spin my tires from a stop with a normal launch (never tried). Only other Diesel I had before was an 03 Duramax that was tuned. Is there some mode I should be in or button to press? I haven’t had it long as I only have 1400 miles on it right now.

Get a banks pedal monster, it really wakes up the diesel.

If you're stock there is no secret sport mode beyond turning off traction control and/or enabling 4WD and flooring it. The throttle (gas pedal (or is it a diesel pedal)) is tuned such that the engine doesn't come alive until it's way down. In the first half to 3/4 of it's travel this thing loves slow and it's a jeep, so slow feels good, as I've stated earlier. This is probably great for crawling, but I'm in NJ and the places we could go as kids either don't exist (smoothed over into malls and business complexes) or are other wise off limits - parks and such.

I also don't have a Rubicon, so my tires are a little smaller/lighter (32's) which helps since we both have the same 3.73 gears in the diesel and an LSD which helps get power to both wheels and limit excessive slipping, though it doesn't completely prevent it like traction control will.

A throttle controller like a Pedal Monster or Pedal Commander would change the relationship of throttle position to engine response and most people here that have tried them swear by them. I have not but may in the future. Keep in mind this does not actually tune your engine, but in today's world of electronic throttle control (meaning the throttle and engine are only connected by an algorithm not an actual physical connection) you're just selecting a more aggressive response which might simply mean when the pedal is 1/2 way down you actually get 50% power potential or more based on your selection.

If you really want more power you need to tune. Banks, GDE, and likely others I'm not thinking of offer tuning which turbo diesels respond really well to.
