CLS-Class (C219) CLS 63 AMG Ratios

[ALI]

lOl man, I know most of us MB faners want to see this video...

And you wont be disappointed , believe me , the E63 shows you exactly where the M5 & E55's weaknesses are , the best thing about the 63 is that it's powerfull in every single slash between 0 and 200 mph , no weak points ..

But again if you expect the E63 to burn the M5 and E55 , then i guess you wont be thrilled , but the E63 is an M5's nightmare to 100 mph , but from there on neither approaches the other , because the M5 picks up its revvs , and the E63 holds on to the same level of power by picking up on its revvs , the 4th gear reaches somewhat 7200 rpm ...

best post from you ever. This is a very unbaised opinion coming from you. Karma well deserved

lOl, I agree with Just_me, good post man but I have a question ALI. Have you driven the M5 and E63 on a side-by side test drive? If you have than you would really know the weak points of both cars in the power bands.

I`m guessing the E63s` AMG modified 7G really helps spread the power evenly through the gear-ratios better than the E55 and might be the reason it`s quicker past 150mph.

Yes GTA , as a matter of fact I did race interlagos's M5 earlier when I even barely had 500 miles on my E63 , off 0 mph , the E63 is a blast so it takes an early deep lead over the M5 , I guess the cut down on torque and the raise from 2650 rpm helped for better skid , and then that 7G helps gain a couple more up to 100 mph , so you can say the E63 is ahead by 21/2 to 3 cars , the m5 gets just a little closer after 130 and it ends there , off rolling start , the M5 took the lead at the horn from 30 mph , but my 63 still caught up before 90 mph and so on ..... Hopefully we'll get it on video sometime

Thanks Just me , I say it honestly , the E63 is not made for major improvement on straight line performance , but it's a way better over all car than the E55 !! LOL

 

[ALI]

Oh , and one more thing GTA , the weaknesses of the E55 and M5 are pretty clear , E55 : at 110 mph , you feel like where the hell did that power go .. M5 : it just doesnt take off as fast , but who can blame the M5 ? Because it's such a masterpiece all together that you just have to love it the way it is ....


As for the E63 , well imho : in this segment , it's just the perfect way to express 514 hp , so balanced , so fast at every point , and it doesnt lack power anywhere what so ever , I guess it has too much going on , the switch from 4th to fifth gear at 140 mph , it held the M5's approach ....

Thanks for the writeup ALI, great posts, very informative!
I remember I posted the power drop-off of the E55 on the MBworld forums, thay thought I was really crazy!
The main problem with the E55 is that it`s massive 516lb-ft is released way too earily! at just 2650rpm it simply didn`t have enough leg room in the upper
rpm range to like the E63 does as you stated. I can only imagine how well the E63 would do with 516lb-ft with the 7G. That would be crazy fast!

Anyway I`m looking forward to that race...

Well interlagos's car is in the shop again for clutch issues , as soon as it's back ill tell him ...

yeah , exactly what im trying to prove here , 2650 rpm so very soon , and then after 100 mph you dont feel any of that torque .....

I am serious , you cant start a rolling start with the E63 anywhere between 20 and 70 mph on manuel mode with ESP ON cause it will skid and interrupt your acceleration , that's where you feel all the torque at , at higher rpm torque , thats why I mentioned earlier , it has no lack of power what so ever .....

Now this is something I didn`t expect of the E63 with the torque band
reached at over 4200rpm, it still has the same tire shreading talent as the E55!

, that's where you feel all the torque at , at higher rpm torque , thats why I mentioned earlier , it has no lack of power what so ever .....

Again this is the advantage of good turque output reached at higher rpm`s.
Just think, the M5s` 383lb-ft of torque might not sound like much but it`s reached at 6100rpm which a hell of a lot of leg room to work with!
One of the main problems with such a hi-rpm band where torque is reached, your off the line starts arn`t that impressive because the engine has to reach deep into it bowels for the power, but once the engine reaches it`s peak (5500-6000rpm) is where your really going to see and feel the difference! (as you noted) I`m glad MB chose this move with the E63. However, when the supposed Bi-Turbo version comes along things are going to change...


Take note, with the M5`s higher-rpm hp and torque bands, it might actually be faster if you delimit both these cars simply because it`s working with more running space (leg room) than the E63. -just a throry of mine.

 

[GTA45E]

Btw ALI, I was about to ask if you had the same experience with the CL65.
Although it has 738lb-ft it`s reported to have a steady peak from 2000-4000rpm which is very early.

Not really , because the torque in the 63 is still deep , so do the math , close 100 lb/ft of torque advantage in the 63 , and 1000 rpm M5 advantage , they are more likely even after 160 , because when i switched from 4th to 5th at aprox 140 + , the 63 held the m5 back to 160 very tightly ...

See the CL65 is a different story , lol that car sounded so deep , it was so fast at every point that i really couldnt tell crap from crap , all i know is that it depends on low revvs , it only revs 5500 rpm anyway ... btw the 55 and 63 are hell of alot more sportier than the 65 engine ....

Hmmm, interesting mathmatics.. I was thinking the M5 would be faster because it`s maximum torque is reached at a higher rpm range, it is a bit weaker than the E63 through in the powerbands so I guess the higher rpms wouldn`t help if you producing less power.

5500rpm.. Thats pretty low midrange. Thats the thing with turbo or Kompressor engines. The power is reached too soon in the rpm range then dies off somewhat when the revs get going! If you ask me a turbo is something needed in a smaller engine where power is most needed in the lower revs. Larger engines like V8s and V12 really don`t need to be turbo charged
simply cause all that power is used to peal tires when taking off when that power can be used at a much higher rpm making the car even faster!

I dont think you get my point here GTA !! THE CL65 was so fast everywhere to 200 mph , so so so so fast !! That's why I tell you I cant tell crap from crap !!

Gotcha!! not only is the engine quit large, it produces an enormous 738lb-ft (@ 2000-4000rpm) which is earth moving in automotive language! I have yet to see a power diagram on the 65 models so I`ll take your woud for it.

I swear , the whole block used to complain about the noise every morning i left to work ...lol
