Mercedes has always tried to stay one step above the competition in terms of straight line performance. The original N/A 55 engines were great in their time, the F/I 55 hauls butt and initially blew everything off the market. Now that BMW has fed the new M5 some spinach, MB will rush to outdo them yet again, alas the new 63 engine.

Mercedes has already released the information about the 63 engine. It will be a N/A 6.2 liter V8 making 503hp, and will be mated to a 7 speed automatic.

However, I don't think MB will attempt to sacrifice ANY power over the 55 engine, therefore I am forced to think that they will attempt to boost overall performance, including low end grunt.

That brings me to my ideas about a F/I 63 engine.

Here is what I think will happen.

C55---->C63 N/A
CLK55-->CLK63 N/A
SLK55-->SLK63 N/A
CLS55-->CLS63 F/I
CL55--->CL55 F/I
E55---->E63 F/I
S55---->S63 F/I

Does this look right?

They may supercharge after a few years but I don't think they will offer forced induction on these motors upon release.

^^^ from waht i read and hear, its gonna be ALL N/A C CLK detuned E63, CLS63, SL63, S63 same engine, and then MAYBE they will release 63 FI,But i would be surprised if they would go with 6.9 Ala their history number N/a engine.

If that makes sense at all.

Roupin,

You will not see a Kompressor version of the 6.3 engine, unfortunately. It is a great motor but the poor gas mileage and emissions are making MB sway away from the Kompressor setup. It seems that we will conitnue to see the TT V12, but for now the 55 & 32K engines are going the way of the dinosaurs...

I will probably be keeping my next 55K car for some time to come. Forced induction trumps any brand loyalty I have. I love having an extra 100-200+hp on tap with choice mods done in a very reliable manner... these high strung, high compression motors just don't offer that...

Marcus Frost is correct.

According to both Motor Trend and Automobile magazines, the new M156 6.2L V8 (N/A 6.3) will find its way into the ML63, CLK63, E63, and R63. Two turbo charged versions of this engine are 'in the works' and will produce 563hp/664lb-ft and 697hp/886lb-ft (but no mention where these engines might end up). Additionally, they state the evolution of the N/A version would be to a increased displacement of 6.8L (N/A 6.9).

That said, I think it's likely that the upper level AMG's (CLS, CL, SL, S) will be getting a SC or TT version of MB's slick new N/A 5.5L V8 (which debuts in the 2007 S550), making 10-20% more HP than what the current SC 5.5L.

There are two turbo versions of the M156 engine under development and slated for future production. The minimalist version will be 563 HP and 664 lb-ft. The maximus version will be 697 HP and 886 lb-ft.

The NA engine will appear next year in the AMG versions of ML63, CLK63, E63, and R63. This engine is also slated to grow to 6.8 ltrs.

My understanding (still mostly rumours and development leaks at this point) is that the 63 engine will work great with the 7 speed transmission despite the loss of torque -- not having driven the combo, I don't know. MBZ will keep the biturbo 12 and the 55 S/C for at least the next couple/few years. And they are working on other new V8's (other than the 63). I am especially interested in their new turbo diesel V8.

one more thing...

one major reason that MB is choosing NA is due to the 7sp box, it can only handle certain amount of torque...

if I remember correctly, the current 5sp can handle 700lbs++ of torque and the new 7sp is around the 500lbs+ of torque...

don't quote exactly, but definately this a documented fact.

Until they find a heavy duty 7 sp, I doub the V12 TT's will have the 7 sp auto for now.

The SLK55 is the only AMG with the 7sp box and it works really well. With only 355/376lbs it easily dips into 12.7 to 12.8 and some members have gone as low as 12.5xx.

Even if the new C AMG keeps the 5.5 l or the 6.3 and tuned to about 410-420hp, the car will definately dip into mid to high 12's with the 7sp AMG box.

I'm guessing...the e,s,m,g, r will get the 490 to 505 tuned 6.3 engine with 470+lbs of torque.. which will make the e very good overall performer.

There been tons of SLK55 and C55 supercharged with 500+ ft of trq and the tranny isstill fine...

..........the current W211 E55 does the 1/4 mile in the low 12's and a few have dipped into the 11's. I just don't see the E63 being faster. The E63 will have to run in the 11's in stock form in order to beat the current E55. I believe the AMGV8K is destined to be a classic. The AMGV8K is such a wonderful engine with such low compression and high potential for modification. To beat the current E55, AMG will have to produce turbo versions of the E63 engine..........something it appears AMG does not wish to do. I understanding is that detuned variants of the of 6liter V8 will appear in C63, CLK63 while the 503HP variant will appear in the e, CLS, CL, SL and S class. further, AMG will continue twin turbo V12 for its S65, SL65 and CL65. These cars will retain the 5speed tranny.

Sure they arent breaking, but its not safe from MB's point of view. Before u can sell a piece of machinery to the public, with a warranty, it has to work way below the limit at which it'd break to be reliable...

Roupin

I hope MB doesn't fall behind on the performance edge, since they started the whole power craze. My only hope is they make a CLK which gets into the mid 12's. I'd love a quick coupe that could match the M6.

In my honest opinion, it seems to me that BMW's overall quality and design have gone down since the American has been in charge over there, and Mercedes-Benz's overall quality and desgin have gone up in the past few years, so I say don't worry about the new AMG motor being underpowered, as long as it is built by the folks in Affalterbach, I'm sure there won't be a problem with satisfying us pistonheads, I say just relax and wait, and get on those order lists!

I don't know guys......................I don't think the genius at Mercedes and AMG are going to make a lesser of a car then the E55.

As a marketing stand point......why? Exactly! They can't and they won't.Too much at stake here with AMG's first production engine. The M5 is killer (E55 is the killer of killers :v )......with that known........who would spend the same, if not more, for an inferior car then the BMW? (aside from the AMG freaks like myself ).And who is to say they won't work on the handling aspect of the E63.Do I think it will handle as well as the M5..............no,but I'm sure it will be nipping at its heals at the track/corners.

My opinion still rides that the W211 e55 is the car to own for a few more years untill they tweak that 6.2 Liter out.(due to the tuning aspect of FI) But........a stock E63 WILL be faster then a stock E55. Period.
A lot of people are counting out the E63 before it arrives ............HELL........BMW lovers thought of the upcoming M5 was the HOLY GRAIL years before it arrived.

IanSL55

Exactly.
