I think my 2011 might be limited to 155mph (250kmh) Did that on the mile long straightaway at BIR (Brainerd International Raceway) last summer
(46°25'18.3"N 94°16'50.0"W)
But that is all it would do, ran out of track. Did not really feel the limiter kick in like my XJ8 does at 126mph.

The speedometer is never traditionally an indicator of top speed. I couldn't even tell you what the max speed is on any of mine lol because it doesn't really matter what it says. I can tell you I've done 150 in my XF though.

And that's just fine. No big deal. I'm just glad they aren't being pressured by the government anymore the way they were in the 80's and 90's which led to the infamous 85mph speedos.

In model year 2011 the speed limiter on 5.0 NA is 121mph, on 5.0 supercharged it is 155mph. This is 121 true, not indicated which tends to be somewhat higher. I have hit this wall a number of times, the car is still pulling hard with obviously a ton of juice left. It is very disappointing to have a quarter of the car's design capability arbitrarily denied to the owner. Jaguar USA has admitted this was done in order to force some sales up to SC and R models, which they feared they could not sell if the more "base" cars had almost the same speed capability. The NA speedo also reads to 180mph, but because of the limiting can only go two thirds of the way.

Before my tune, my 2011 XFR would indicate about 162 on the speedometer as the limiter kicked in and stopped the acceleration. GPS indication was closer to about 157-158 range.
After my tune, I have had the car indicating 175 with a GPS log showing only a 0.5 (negligible) difference.
Next time you see a radar speed sign, set your cruise control to 60mph. You'll see the radar reading back about 57-58!

After the decision was made to deliver the cars to the North American market limited to 121mph, the next decision was to save money by delivering them with H rated (130mph) tires. Cars delivered to European markets are unlimited or limited much higher and are delivered with higher speed rated tires. Imagine them trying to sell a nearly 400hp sports luxury sedan like the XF in Germany or Italy with such a low top speed.
