Top Speed

[liquids]

Not necessarily true. You are making to assumptions: 1- that there is not a speed limiter set by the factory below the capability of the car. 2- you assume that both have the horses to red line the rpm in the highest gear.
Very few cars can do that, and the lower geared may have an advantage.

@Dan S look at it this way. I have a rubicon manual transmission. In 6 gear, at 2500 rpm cruises at about 75 mph. That means that at 5000 rpm it would reach 150 mph. The only problem is that even if the speed were not limited electronically, the engine does not have the power to overcome the wind resistance to climb all the way to 5000 rpm, let alone reaching the red line.

(Someone revived this thread, not me, so here's my .02)
Transmission gear selection will have an effect on reaching top capable speed. When my 3.8 M/T JKU was new I wanted to know how fast it would go. On a dead flat straight treeless stretch of interstate on a winter Sunday morning 20 miles out of nowhere I accelerated in sixth to the highest speed I could get to: 93. I noticed the tach was at about 3000. I downshifted to 5th and was accelerating through 103 when the radar detector went off. (30 seconds later the state po po went by on the other side ... no tickie)

Point being, the torque (not hp) wasn't there in 6th at 3000 rpms to overcome wind resistance, but it was there in 5th at 3600 rpms. Theoretically, and assuming the tires could handle it and the engine wasn't electronically limited, one should be able to redline the engine through each M/T gear to make it to whatever the max speed really is. My gut feeling is about 140, again assuming tires that could handle it.

I went 105 pulling from 80 - flat ground. I had clear visibility at least 8 miles of open road in front of me no hedges/deer/trees. Speed limit was 65 everyone was going 80+ before that I was limited to 98. I touched 105 and dropped back down to traffic speed. Standard Dueler A/T Jeep Sport.

Most of these come with R or T rates tires. Maybe even Q as a dealer option. I’d bet it’s governed at or about 106-112.
