These numbers are conservative.
Sure it is possible. MT showed 0-60 for the SLK55 @4.2 s. I am sure that the E63 with the 7G will do 4.2-4.3s.If you want the best results try the C mode for less wheelspin.
My 2 cents

how will C mode make less wheelspin? i thought Comfort mode simply uses slower smoother shifts.

 

C mode starts in second

 

i think the weight of the car had most to do with it. horsepower is not necessarily the tell tell of how fast a car will be (obviously it plays a huge factor). once you get past the 1/4 mile and really stretch the cars out, the horsepower will kick in and probably pass the SLK55. i think all the new 63 engines need to be tested over time. most cars in their "first generation" have the most bugs and problems. also i think the 63 should be broken in a little more. perhaps the NA engine needs some tweaking here and there. i would not trade in my SL55 for a SL63 if they ever make one. obviously there are differences but not enough to trade IMO.

 

You guys need to stop with this "break-in" nonsense... yes, the car may pick up a little bit of power after being broken in, but having to read this response over and over again is humorous at best. It's like when people keep saying "oh, but you'll be able to upgrade the E63 and make it fast" - yeah, good luck getting the 7-speed to take any more power...

Here's the bottom line folks, listen up:

IF THE E63 IS SLOW STOCK, NO AMOUNT OF BREAK-IN IS GOING TO CHANGE THAT...

It seems like the E63 is just not going to live up to expectations... even if from some of us they weren't very high.

I really don't want to rag on MB... but the ball may have been dropped by AMG with this 6.3L motor...

We have one or two instances in which the car didn't wow and that is enough to write the car off? That is nonsense. Until the U.S. mags do a test of the cars I think judgement should be withheld, or at least until after this big race event everyone is talking about.

I suggest any reputable magazine would be fine, where ever in the world!

 

About the break in. I don't think anybody here believes that the engine itself actually has to be broken in for it to go from 0-60 in 5 seconds to 4.2 seconds. What people are saying is that the ECU itself is limited for the first 1000-3000 miles. After that, either the ECU itself or service will change it so it can run at its full capacity. Whether this is true or not is yet to be tested.

About the 7 speed tranny...I don't have the AMG version (from which I hear is the same 7gtronic just with different software), but performance wise I see it as a pretty big upgrade from the normal 5 speed. The problem with it is it is very jerky and you are constantly shifting and sometimes you have to downshift 3 gears which can take a second or two. Within the past couple of months I've been very harsh to the tranny, like downshifting to slow the car down, downshifting to redline, and keeping the car in a lower gear for an extended period of time (I got friends in the car and its cool to show off). A month ago I got nitrous oxide, I've already used 2 bottles. This past week, the tranny has been acting up. When driving slow and cruising to work, it shifts extremely hard and sometimes feels like the gears are slipping or like it goes in neutral for a second. Also, a couple of times when I stopped at a right light the car started to shake. When I popped it in neutral it was fine. Its either the tranny is breaking because I abused it, or maybe my 75 shot gave it too much torque for the tranny? Considering its not the AMG 7 speed, maybe it couldnt handle the high torque? If thats the case, imagine a E63 with headers, ECU, and exhaust? That would probably bring the torque high enough to overload the tranny. If you put a t/c, s/c, or NOS setup on a 63 AMG, it would probably destroy the tranny.

 

Are you serious with this post?

 

Of course not, I just come on these forums to BS and misinform people Lol

Yes I'm serious. I keep the car in lower gears when racing or if I'm showing off the speed of my car to somebody because it takes way too long for the tranny to downshift itself when you just floor it. My car is under warranty so if this problem gets worse, I'll just bring it to the dealer.

 

Nevermind this, I just remembered that there is an SLK55 Renntech and a SLK55 Kleeman somewhere on these forums that have huge amounts of torque and comes with the 7 speed. So, I guess there is still room to mod Anybody know how much tq these guy's cars have so we can see what the 7 speed can really handle?

 

and above that:


Thanks, on behalf of everyone denied a legitimate warranty claim, for being party to fraud.

 

Boohoo, lets all give ChicagoX a hug. Besides being completely and blaming me for your (and some other peoples) problems and accusing me of fraud, I said the 7 speed was always jerky and never any good. It kept feeling worse and worse. I already took my car in for tranny issues a year ago and MB said they couldn't find a problem with it. Whether the nitrous worsened the issue or not is debatable. If you have a legit warranty issue, MB should help you out with no questions asked. Maybe the service department b!tched you around. Let's be constructive here, if you have something to say to me personally, send me a PM. I'm just trying to share my experiences and learn from others. Not listen to .

Sorry for the little rant, I just don't know why people try to start things. Now, back on topic...

If you look at those acceleration reading, they state that its a 0-100 kilometers/hour, not mph. So, the 0-60 is probably .1 second less for both the E63 and M5. I have also seen the M5 run 0-60's in the 4.2 range from various magazines (car and driver and road and track I believe). This might have just been a bad day or not the greatest driver. I think that R&T gave the E55 Wagon a 0-60 of 4.2 seconds and the Corvette C6 Z06 3.5 seconds. So these numbers will probably be all over the place.

 

No problems w/ service here.

You "cool to show off" types are always the first to cry like spanked girls when the stealership denies you.

Enjoy !

 

I admit that if the dealer denies a claim, I'll try to fight them, but I won't be upset at MB. Everybody knows that with mods you pay a price and take risks.

 

My time slip (RIGHT lane) from a couple weeks back. Car is completely stock and had aprx 3000km on it at that time. I was pleased with the result, but honestly I think it would (should) be no match for a new E63 - as some one else mentioned, I'd wait til some owners have posted their own time slips before making a final judgement.
