Got my GTS up to 179 MPH a couple days ago. No drama at all, the handling felt just about as good as at lower speeds. Quiet too.

This was at around 4500' altitude and the effective HP at that altitude is around 370 HP so it should be able to go faster at lower elevations.

Since the end of the road was going uphill I didn't try longer to get up to a higher speed. Is the Panamera speed limited?

 

Wow! That's fast!

 

You beat me. My answer is irrelevant.

 

Other than as a passenger in a jet, I've never been anywhere near that speed. I hope at the time you were doing that you were on a track.

 

+1. I've only driven a Panamera for a short while, and you've got me beat by a LONG shot.

 

Drag limited to the best of my knowledge, not speed limited. Must have been a heck of a straight to achieve those speeds

 

250km/h on a public road......off course that public road happened to be an unrestricted German autobahn

 

That's about 155 MPH. And I assume alongside other traffic? Nice!

It handles very well at high speed, doesn't it?

 

+1...

 

Oops, I meant 155. It was a typo.

 

Would have maybe tried to go faster, but I was driving in the powerkit and it was getting dark when I had done the 500kms.

As I am not very used to high speeds (we have a speed limit of 120km/h) I only went above 200km/h on 3 lane roads that were pretty empty. But for a 400km journey doing 180km/h for like an hour without slowing down is really cool. Sadly there are a lot of restricted parts now, although I sort of understand it as there are lots of crazy people like once in winter: the left lane was not plowed and there was heavy snowfall. I was doing like 90km/h on the right lane with winter wheels with the 997tt and a Ford Puma passed me doing like 200km/h on the left lane... Insane!

After driving other cars there also like the E39 M5, E55 AMG, CLS 55 AMG, 997tt there, I have to say the PTT is the most relaxed at high speeds (+200km/h), you never feel like you are going as fast as you are going, you can listen to music and speak at normal volume and on speakerphone and there is never a sense of lack of power and the car is glued to the road. Teased a Maserati Quatroporte a Bentley and a Carrera S while there, they just seemed like they were not pushing it (although I saw they did), thats how slow they looked compared to my car, then when I slowed they rocketed past me at insane speeds. In the 997tt the experience was cool, but not very relaxing with all the bumps coming in the ****pit and the noise feels like the engine is glued to your back. We made a lot of stops to stretch out. With the PTT you feel like you can go and go. In a way it felt like doing 170km/h in a VW Lupo rental car, which I have also done there . Its really the best autobahn car I have ever driven. The 55 AMG's however were also really good, they really perform best at the autobahn, the 700nm of torque felt really good.

Cant wait to go there again... If you have something like a EURO delivery program like the BMW M5, I can strongly recommend the experience.

 

Don't have ***** to do this on a public road...Straight to jail no matter whom you hire. One day...Autobahn, here I come!

 

Jail is not the biggest problem, you will kill yourself or someone else, as there is no way the other drivers can antcipate someone coming at that speed. In Germany everyone knows there might be someone coming at that speed.

I was once blinking left to take the left lane on a 120km/h limit doing about 123km/h, looked once in the mirror before putting the blinker on and when I looked in the mirror again and started moving to the left and saw somekind of shadow in the corner of my eye approaching. Pulled quickley back and then two motorcycles doing about 300km/h passed me about a tenth of a second later. If I wouldnt have noticed him, they would have both be killed at that place. Most people are not this observant and just change lanes without looking or blinking.

 

You make an excellent point in my opinion...and this is not intended as a slap or criticism against the OP...at these speeds things happen faster than the eye can sometimes see. A few months ago, I was reading about a terrible accident on the Autobahn involving a family that was traveling in a series of high-performance cars and another vehicle that suddenly merged into their lane. As I recall the article, there was a terrible collision when the other vehicle merged into the left lane. The driver of the merging vehicle looked first and didn't see an approaching vehicle then merged and collided with one of the family vehicles. Investigators determined that a rise in the road behind the merging vehicle probably inhibited the merging driver's vision and that the closing speed of the approaching vehicle was rapid enough to cover the distance between the rise and the point of the merger. The result was a terrible accident where speed was THE factor, but technically, none of the drivers behaved illegaly.

I am thrilled by the performance capabilities of my 4S. This is my first Porsche in almost 35 years of car ownership and I am more than impressed and grateful to this company for developing a vehicle like the Panamera. I've probably driven the car at speeds approaching 80mph on the highway...and I was traveling with the traffic. I feel about this car much the same way I felt about my former M6: I don't have to advertise, it's enough that I know what this car can do.

 

I understand the concerns for other people when doing this type of thing. That was my primary consideration and it was planned for. This wasn't just a spur of the moment "hey, let's see what this car can do."

The stretch of road was completely deserted with 100% certainty that there were no cars, pedestrians, intersections, or objects that could be hit if the car went off the road. Just level dirt on either side.

I was wondering whether I should put a disclaimer in my original post warning other people not to do this in unsafe conditions, but I figured the people here were sensible enough to know that.
