damn that will be awesome. The way production power figures have been increasing over the recent years, id believe anything is possible!

whats the new m3 going to have?

C43AMG

It's getting the V8 for the older M5 - 400HP

ItalianStallion

Yeah, lol, thanks. If the current CLK55 and C55 have the same engine specs, then why wouldn't the new C63 and CLK63 have the same engine specs? Plus, I haven't heard any news of a significantly detuned 6.3 AMG Engine, it seems like the CLK63 has the most detuned version. Why would AMG detune their engine that much?

I wonder what kind of performance mods there will be for these new 6.3 Liter AMG Engines. Since they are naturally aspirated, I doubt a chipped and pullied 6.3 will be able to compete with a chipped and pullied 5.5 Kompressor. Still, I heard that the new Lorinsor S550 with just chip, exhaust, and intake mods increased the horse from 385 to 420, so there is hope that this new batch of Mercedes engines will be moddable. The other problem would be the limits of the tranny...oh well.

dragonAMG

I don't understand why they would detune the 6.3??? Why not just extract more HP out of the 5.5? That would make more sense, wouldn't it?

C43AMG

Doesn't that always seem to be the problem.

2QUIK4U

I agree, plus it would probably be much cheaper for them to use the 5.5 than the 6.3. Hence, I think that the next c-class AMG will have an increased output 5.5 liter and additionally there might be a C63 as sort of a limited edition.

e1000

lol - we all know how AMG "detunes" engines...... (see E55 vs. SL55)

PC Valkyrie

Not true. The V8 in the upcoming M3 will be a brand new unit derived from the V10 of the current M5 (in other words, they just take away 2 cylinders).

2QUIK4U

I wonder what the characteristics of this new BMW engine will be like. Anybody have any torque band/figures yet. Knowing BMW's M division, it will probably be a hi-rev V8 and will be more comparable to the Audi RS4 powerplant than the C55 engine.

I think AMG will stop 5.5L engine production in the near future, and keep their portfolion into two engines, 6.3 and 6.0 biturbo. That's the main reason the new C will get a detuned 6.3 instead of a more enhanced 5.5

W204 better offers Comfort Access which I always wanted on a C-Class. I don't mind it is only 10% gain in hp so long it keeps a good gas milege as the C55. I love to try the AMG version of 7G-tronic and hopefully C63 will have a coupe version if the rumour becomes true? At any cost, I want mp3/DVD playback capability on my next C-Class. Paranomic sunroof is definitely something they should consider for the W204. It will be nice if I can also add Distronic to the W204 and I also hope Neck Pro becomes a standard option in C-class. I am patiently waiting.

cntlaw

i thought the 55 kompressor engine already stopped production? On our local MB web site, I can only find E63, CLS63...

2MANYCARS

If possible, please find out the detailed spec's between the C63 engine & CLS63's. If the layout of both engines are the same, meaning cams duration and lift, valvetrain, head flow, short block setup, etc., then there's hope that we can bring it up to 507hp safely and reliably. Intakes and exhaust would not be a problem, since custom fabrication is around. If everything works out as mention above, the C63 will be the fastest in the next AMG line up given its advantage in weight.

eLTURCOamg

i can hop into this, my family owns gas stations all over ny, all of our stations carry a premium grade with minimum octane of 93, but we do have stations which sells leaded and unleaded cam fuels, but you also have to take intoconsideration it has a MINIMUM rating, usually the ocatane points are 1 or 2 higher then listed

Germancar1

What you say is correct technically which is why the C63 won't have the full power of the new 6.2L V8. Mercedes isn't going to allow the C63 to be faster than the twice as expensive SL/CL/S 63 models. The C63 will likely get just enough hp to outdo the RS4 and new M3, both around 420hp so look for the Benz to get 445-450hp but with much more torque than either the Audi or BMW.

knepster

i still think 450 hp is pushing it. I agree the torque will be massive. Even at 420-425, the C63 should take the RS4.

Germancar1

Well I'm just looking at the CLK63. I never thought MB would give the CLK more hp than the outgoing E55! That is crazy power for a CLK.

IMHO there will be 2 AMG engines for the new C class.

There will be the 'enhanced' 5,5 liter to about 400 HP

Secondly they will offer a limited, very high priced C63 with around 480 HP (limited version).

360_iti

I think 2007 SL55 is still in production.

I believe 5.5L AMG engine won't be used in 2008 anymore. I don't see why MB would need to release a limited, very high priced C class (as their entry class).

360_iti

The current E55 uses the exact same engine as SL55 and CL55 do which is supercharged V8 5.5L, and E55 doesn't have 469 hp. Based on dyno numbers, the E55 actually has +/- 500 hp. It is well known that the publicized "469 hp" is just their strategy to keep the SL55, CL55 buyers happy. Therefore, the CLK63 actually doesn't have more horsepower than the current E55.

In addition, E63 is coming this fall with 500+ hp. Again, this "500+ hp" will be their publicized numbers, in reality the numbers could be higher, just like in E55 case.

ItalianStallion

You could say the same thing about the CLK63 that MB could just be giving us the 480hp number so that the CL/E/S/CLS owners will be happy. It might have the full 507 or whatever hp number that the bigger Benzes will have, but only the dyno will tell. I just don't understand why if Mercedes already has a (possibly) detuned 63 engine (the one in the CLK63), why would they detune it even more with the C63? Then again, AMG has made the class exclusive C32 before, so maybe they will also make a seperate engine or another variation of it.

360_iti

That's right. Only the dyno will tell.
Looking at the current model, C55 has the same engine and power rating as CLK55 (5.5L N/A, 360+ hp). So based on the history, there's a chance that the next upcoming C63 will have the same power rating as CLK63.

cntlaw

Unlike the 5.5 CLK55 , our local price of CLK63 and E63 are the same. Thus, there is no point to 'please' the E63 owner because they are not paying more than the CLK63 owner. The only reason to explain is the 63 engine is more a design efficient if with 481hp , and the heavy weight E63 is treated a less effiency boost up version of the 63 which is 514hp in order to compensate its performance loss due to weight. I know this is my bull****, but that is what I can think of.

cntlaw

The only reason I would explain is MB does not make SL63 either a production schedule issue or they do not want to adversely upset the SL65 marketing line. Just a guess.

Germancar1

Yeah that I do remember when the E55 was said to outperform the SL55 so they adjusted the SL55 to "493" hp to give it the edge. Then again the CLK63 could be underrated too so it could have more power than the outgoing E55?
