US maximum speed limits are ridiculous and unnecessary. The Germans have areas on the Autobahn were there are no maximum speed limits, weather ard traffic conditions permitting, and their accident rate is excellent. There are several reasons, rigorous driver training, very through car inspections, high quality roads and good lane discipline (slower drivers keep in the right lane(s)). Most cars in Europe are limited to 155mph and most of my German friends know exactly the top speed of their cars or motorbikes. I’ve driven a BMW motorbike on the Autobahn at something more than 170 mph, wasn’t really terribly focused on the speedometer so I don’t know the exact number. The fact that it’s legal, in safe areas, reduces the temptation for people to do stupid things in unsafe areas. I’ve always believed that one reason German cars are so good is that they’re designed to be driven on the Autobahn.

125 mph...off a cliff maybe. There is no way a billboard goes 125 mph with a stock engine on flat ground.
6 lane highways with an open speed limit.

Rubicon is geared lower... Of course it tops out before a Sport or Sahara.
Yep, this is your answer. 4.10s vs. 3.43 or 3.73. The higher the axle ratio the lower the top end.

And for those that are city bound, Wyoming has a “safe speed limit” where 100MPH is considered reasonable under certain conditions. Then there’s the Silver State Classic Challenge held on Nevada's Route 318, with a record average race speed of 219.6 mph.

Hey, but what do I know? I own a Hellcat and have never, ever been over 175MPH on a public road. Nope, not me. I always drive 10MPH under the posted speed limit...and wear a helmet, even when walking on a sidewalk.

Some of you really need to do some learning before posting incorrect BS like this.

Higher numerically numbered gear ratios are LOWER than lower numerically numbered ratios.

4.10s are LOWER gears than 3.45 or 3.70s. LOWER gear ratios usually result in lower top speed.

3.45s and 3.73s are HIGHER or TALLER gears than 4.10s and would usually result in higher top speed.

Higher number, as in 4.10 is higher than 3.73 and 3.45. Not gears.

You call me a moron.....? Never in my life have I seen a bunch of clueless, know it all dickheads like you and others on this site. Why don't you go over to Pirate and tell them about your "higher" gears. Maybe you could give them an education like you provide to the other morons on here.

You and the rest of your moron brothers on this site can kiss my ass.......bye....

Well, I got my JLUS up to 105 mph on interstate 10, in the clear. The front end started to vibrate a little and I backed off. It has a Mopar 2” lift with BFG KO2 35” tires. Now that i’ve done it, don’t feel the need to do it again. I use to fly helicopters in the USAF, so I’m kinda pushing things, but always calculate my risk.

Where do you find a road with a speed limit that high?
Have you driven in Comifornia lately? 80 is the new 65 and the brainless are doing 100 on a regular basis where I live.

I have noticed that Wrangler drivers keep it in the 60-70mph range for the most part.

I'm not opposed to speed when done safely in a controlled environment but when you put others at risk (public roads) I have a problem with that and I feel most others do as well. Drive safe, drive smart. Cheers.

That's not a road and the answer I think would be Montana. At least I know that there was no daytime speed limit on some roads there a one time, not sure if that is still the case though.

The Rubi with 4.10s vs 3.45s would top off at a lower speed if all else was equal. The Rubi with 33" tires however somewhat negates the lower 4.10 gear so I'd guess the final drive ratio between the two is pretty close...

My friend owns a 2018 Rubi 2 doors, he have mentioned that his jeep doesn't go over 100mph maximum speed. Anyone has the same top speed ?
In May, when I had 800 miles on my 2018, 2dr Jl with 3.6L....... Was by myself... I ran it up on the interstate to see what top speed was.... no other vehicles were within miles.... Yup, 100 mph was it.

Like many others I suspect, I'm bowing out of commenting on the speed specifics of this thread, until now silently.

Don't get me wrong, people have a right to ask, ponder questions like what speed would a drive train built around handling rough terrain be able to do in terms of speed, but it may encourage non-close course testing of same for bragging rights at the risk, as well stated by others before me, of property and safety.

To me though, it's kind of a little bit like talking of a Corvette's off road performance, worse, its crash worthiness (historically bad given its built for speed original light fiberglass chassis, I understand today made of stronger composites(?))

Still more, I can even see legitimate scenarios where such questions require answer. For example, the State Department, charged with insuring the protection of our country's negotiators, who may find themselves needing to meet on the soil (of should I say sand) of some foreign dignitary's desert compound, might be interested in the use of off road vehicles like the Wrangler for the ride, if not also equally interested in its ability to handle evasive maneuvers in the areas of handling and speed, should an emergency necessitate the evacuation of a dignitary from an active or emergent kill zone.

Of course, none of us bought our Wranglers for speed or great gas mileage.
