E63 AMG 4MATIC
@Amg63-: I was the owner of the CLS. As stated above, the driver of the silver E63 told me that it was tuned as well (apparently producing even more hp than my CLS given the newer tune). As you correctly say there should not be such a difference in performance assuming that both cars had a similar weight. My only explanation is that the owner of the E63 was simply not telling the truth and his car was in fact completely stock (although I don’t know why someone would blatantly lie about this at a race event...).

As for the video of the E63 vs. the Audi TT: please note that this is not the E63 I raced against, but another one (albeit similar-looking). Both races took place at the same race event close to Berlin (Germany) in August 2014.

As for the additional videos of the CLS, I was just providing them “as courtesy” so that you can see how it performed vs. other cars.

Ok then so the owner of the E63 clearly straight up lied about his car having ANY tune on it at all, let alone a "better" version of the same tune you are running.

Its ridiculous how someone would lie about that and actually think his stock E would have any chance in keeping up with a tuned CLS. I guess he didn't mind knowing he would make a fool out of himself.

This still and never will make any sense, sorry.

It's entirely possible that there was something else wrong with the car so let's not accuse anyone of lying just yet...

yea and even more of a surprise that the guy with the E said he had an "improved" version of the same tune by same company who tuned the CLS lol

I just realized that the e63 NON S in this video has only 531 tq vs the 590tq of the RWD. Yes both have 550bhp but the torque difference between them is HUGE. That shouldn't be overlooked as if it won't change the outcome here

so isn't the torque advanatge the main reason why the RWD caught up by the time they reached 125+mph more so than the drivetrain being a little more efficient at higher speed?

with same torque levels on both does anyone think/know if the RWD will ever catch up before the 4matic reaches the speed limiter?

no problem -- yeah it's annoying ... if they are going to take the time to post the video, even in some cases take the video, I'm not exactly sure why they post the wrong information especially if they want to showcase the car

4MATIC center differential

im not sure that reason pertains to 4matics since we dont have the torsen diff like quattros, ours are open diffs and traction control is controlled by Electronic Traction System... one of the reason our 4matics have a much higher tolerance between front and rear rolling radius on tires than quattro system.. (esp is a reason too).
I'm a bit confused about what you think of the center diff, but I think the 4MATICS in the E63 AMG do have a center differential. It uses a planetary gear set to create the 67% rear torque bias. These links help show it:
http://www.awdwiki.com/images/merced...matic-w221.jpg

This one is not exactly the same, but does a good job of showing the torque split:

http://www.awdwiki.com/images/merced...ic-w210_xx.jpg

I think the 2018 model with "drift" capability will allow a RWD mode. So it may have AWD at the start line, and then switch to RWD.

Happy Holidays!

perhaps my vernacular was confusing , what i meant was the 4 matic center diff is not like the quattro one... quattro is toreson diff and our is open diff

Just curious whats the technical reason that having an open diff results in less drivetrain loss than a torsen diff?

. Less moving parts= less lost in those additional moving parts

Can't say I've ever noticed that on several cars I've dynoed before and after without and with lsd. I don't think that's it

if you're going solely off Dyno numbers then awd vs rwd is really no diff then since they both dyno about 600whp tuned ..... but we know that's not the true story in awd vs rwd efficiency so bringing up dyno is kinda pointless since on our cars rwd don't dyno higher than rwd by any significant amount

so based off dynos they seem to be the same but I guess it's because dynos aren't showing that the difference in power only starts to show up at speeds of 125mph+

If anyone in the Texas with an e63 wants to race lets set it up. I'm currently untuned but have catless DPs.

most people dyno our cars in 5th gear which goes well past 125mph by end of dyno run at top of rev range ... so that difference doesn't show up in 5th gear dynos
