How come Porsche cars aren't subjected to eletronic speed limiting?

it really is dumb how they find "electronic limiters" against their philosophy, but when they get the chance to make a truely incredible car they opt out in preference of keeping their dumbass namesake 911 at the tops. I mean it makes perfect marketing sense and all, but its still gay as hell. Before the Cayman fiasco i secretly loved Porsche, now i feel a bit bored whenever i see one.

Coming to think about it, it's surprisingly weird it is to permanently remove the ESP in mercs. I've seen my friend unlocking it and I have to say, it isnt the most fool proof of methods, using a certain combination of the control buttons

Most it not all cars have a code for completely removing the DSC/TCS/ESP whatever you call it so it wouldn't surprise me there is a combination to override the speed limiter as well. I think you would be mad not to get it removed on some of the faster cars. You are only ever using a percentage of the cars potential.

I know with Benzes of not that long ago, you could do a combination of voodoo magic to get the ESP completely off. It's called "Dyno Mode", and would also disable the ABS and anything else that might freak out on a dyno where only two wheels are moving.

Isn't 250kph the top speed of these limited cars. How can that be a level ?

Well ever since the cayenne and the boxster we pretty much know that Porsche is really mainly about making money just like any company, but you can´t really blame them for it. They´ve effectively and stubbornly engineered all the problems out of the essentially flawed RR concept, so they´d be stupid not to make sure the 911 stays top dog. Slightly similar to the Chevy engineers, who decided to stick with leaf springs on the Corvette, and amazingly, they´ve made that work perfectly as well.

yeah it´s like, you press the esp button 4 times, then you turn the light switch 2.5 times while gently scratching your left testicle with the car in reverse, and voilá, it works... something like that...

My friend's M3 has had the speed limiter removed, and it certainly hasn't fallen to bits yet with some well chosen, simple, effective upgrades.

absolutely bollocks, AMGs were made to do that kind of speed, it is COMPLETELY safe to remove the limiter and hit topspeed, the Y rated tyres are made to handle 200mph, unless you have kak tyres like (R, S, T, U, H) then its different story.

There is a good reason why they charge you a fortune for each tyre, its quality stuff, so use it.

DTMracer is a bit right.. Merc sells an AMG extra kit that will raise the limiter to around 170~mph, and i would assume the cars could do and might be tested to do more.

All the Merc AMG and cars with the AMG-Sport Kit do come with high speed rated tires and it does charge a lot (I just changed my front) but the Y are rated only to 300kph (186mph) so a 200mph run is not going to be very nice. But there is other factors like how much down force is being created at speed (or lift), suspension, and etc. I dont want to test my Merc in that area as I like my life and the crazy days are over.

pffft. so all those countless 200mph stock-car videos on youtube are what?? CG & video editing?? Its not crazy nor risky, cars are rock solid at that kind of speed, it may not be as stable as race cars, you will get some weaving and feel the whole "lift" process, but its very mild, nothing scary.

it is safe, and it is fine to do those kind of speed. your AMG car & tyres are made for that. If you are going to be happy with 155mph, then stick with the puny C350.

The big boys push their cars to the limit.

That is hitting the brakes hard at close to 200mph, and i dont see tyres explode or anything.

remember that there are some ppl who do 150+mph run everyday to work on the autobahn.

[edkwon]

how much do ppl really care about the top speeds if they owned those powerhouse cars anyway (esp in countries without autobahn type unlimited speed roads)?

as far as im concerned, its purely for bragging rights, and driving either on a high oval/straight (a simple-minded or drag racers idea of fun, not mine).

what i want those cars for is the passing power at realistic speeds, the top speed is simply a byproduct. but living in the US i cant think of any reasons to drive faster than 150 mph in a non track situation other than to wag my e-penis around.

its an entirely diff matter in europe when ppl can actually legally drive faster than 150 mph as part of their commute, then there is some merit to considering top speed capabilities.

[Ford Prefect]

I get the feeling you guys think all the germans drive to work at mach 1... if you have a 250+ car the opportunities for driving this fast are quite rare even in autbahnland...

yeah that´s Striezel Stuck, and he is, in fact, one of the very very few real big boys as you call them...

[cdbob]

Tbe M5 and M6 both handle 200+ fine, if they were not designed to go the fast the gearing would not allow them to go that high and they would be have all the features to make the car steady at that speed, its just an agreement that saves them money by weeding out the drivers who want to go fast with the ones that just want a fast BMW or Mercedes. It's a lot for the person to want to go 200 then the person to be testing to see how fast their car goes (the average person) on the autobahn. The agreement makes perfect sense.

[aus_jimmy]

You guys have it all wrong. The speed limiters are put in place from the factory in conjunction with the load / speed rating on the tyres. This is how the car is complianced as well.

imagine if BMW/Merc/Porsche sold there fastest cars with no speed limiters in place and put tyres on the cars that could only go 250 kp/h when we all know that some cars are more than capable of doing well over 300kp/h


So all this other bullshit does not make sense. Considering that the only thing that keeps you on the road is those black round things. If it was not for them you wouldnt be going very fast at all.

First thing is there is a few cars that are stock 200mph ready, like I said the Y-Rated tires are NOT RATED FOR 200MPH. They are actually rated for 186MPH. There is (Y)-Rated tires that have been rated for 186+mph, and, not even AMG ship with those as OE, you have to go after market and buy them.

And to say 200mph is safe is just stupid and dumb. You have to take in to consideration PSI in the tire, as the heat its going to generate and could cause your pressure to spike.
There might be a bunch of video on youtube but it does not mean people do it every day and its normal and safe. If i wanted to make a 200mph, yeah its do able if i get my car prep'ed but on streets roads in the US, no thanks.
And to say people in Europe (mainly Germany and those roads go to no where and are getting fewer and fewer each year) do 150mph runs is totally different then 200mph. The power, speed, and physics involved is totally different at 150mph then at 200mph. To get a car doing 150 is not as hard as getting a car to hit or crack 200mph.

And I am happy with my S500, knowing that I can hit 155+mph and dont need to prove to you I am some big boy

once again, if a german manufacturer is willing to take the limiter off your car, they will sure as hell know what they´re doing...

since this is germany, it is very likely that you have to change the documents of your car to include the new top speed, and the minimum requirements of the tires you can run without dying...

well anyone who decides to go 300+ km/h with the wrong tire pressure is obviously a complete idiot, but this is how the whole darwin thing works...

actually the derestricted parts are mainly the roads that actually do go somewhere, a lot of these are on the main connecting highways, so when you drive long distances you usually get quite a lot of them... but that doesn´t change the fact that even at night you´ll have trouble actually keeping it above the 250 mark for a very long time, simply because there is always some slow traffic, and it is quite hard indeed for a car to keep accelerating beyond those speeds...

[Zwaplat]

Stop saying "in Europe" when you talk about unrestricted roads. The only places in Europe where you can legally drive your cars' top speed, are the derestricted autobahnen in Germany and race tracks.
If anyone else knows another country in Europe where you can drive as fast as you like, please do tell.

It's not because some Dutchies and French idiots think Belgian roads are unlimited because they're wide, that it is actually the case.

Isle of Man. Although I doubt you'll be going 300km/h anywhere there

well the sort of roads where you can´t go that fast even if you really wanted to are the most fun anyway

I have worked that out by now. Could you please tell your government (or however is in charge these days) to stop spaming me? It is rather annoying... And since Christmas is coming up, please remove those mobile speed cameras, they really ruin my day.

The Isle of Man has still gotten some unrestricted roads, it is scary as hell to go faster than 130mph, but it was a good training for the Autobahn 8) I doubt however that one can hit 200mph there.
