Benz says they will fit....

From Autoweek....info on C is at the bottom.

In what Mercedes-Benz claims to be the most powerful, naturally aspirated eight-cylinder engine extant, the firm’s performance arm has developed a powerplant that will make it into virtually all its high-horsepower models.

M-B claims the 6.2-liter V8 develops “a minimum” of 510 horsepower and 464 lb-ft of torque without a supercharger, and has 20 percent more torque than other free-breathing engines in class. Cars fitted with the engine will get a 6.3-liter badge.

The engine and cylinder heads are high-strength aluminum and created with the latest metallurgical technology. Cylinder walls undergo a process to minimize friction, increase durability and add strength: The cylinder walls are twice as hard as conventional cast-iron liners.

AMG developed the engine without Mer-cedes. It has a throaty exhaust note reminiscent of late-1960s Trans-Am cars. It not only sounds better than the supercharged 5.4-liter models it replaces, it is smaller and lighter—438 pounds vs. 485 pounds.

AMG fitted a CLK DTM street racer with an engine for drive impressions. A bit of a shell game, on-site engineers privately agreed the car developed near 580 horsepower. Regardless, at first blush and full throttle the engine is a torque beast. That the 6.3 can fit in a current C-Class lends expectations that of the 24,000 engines AMG can build annually, they will be spread across the lineup. The 6.3 debuts at this fall’s Frankfurt show in an M-Class. It will be available in the States next year.

From a marketing standpoint I can't see how they can pull off putting it in the C-class, but if they do, I will buy one.

bobsc32

That's why they can do it!

no matter what we gonna name the next generation of C-Class, or what we have heard how many powerful engines MB is going to produce; the C-Class will get something at max. 400-440hp , just to match with new M3/4, RS4.

EKaru

Exactly.... That big 6.3 will be reserved for the big guys (E + S-class cars)...

I was referring to the fact that the E/S/SL/CL cars would have to have more powerful engines IMO to keep those enthusiasts happy. I would think a lot of E55 owners would think twice about a 510hp E-class when a 510hp C-class would be as fast or faster and it actually handles pretty well unlike its fatter sister.

EKaru

Most of us C55 buyers could have bought 03' E55s if we really wanted to... I test drove the E55 before going for the C55. The E55 was fast as sin and it had more room... The end. It weighs over 4,000 lbs and felt like it too. The only part that suggested sports sedan to me was its acceleration, but it handled like a big heavy car. In contrast the Audi RS6 weighs a little more than the E55, though it feels like it weighs way less, which suggests that it's a well engineered car.. Anyways back to the subject, if they made an AMG C-class with the same power output as an E-class AMG car then I'd go for the C63 in a heart beat as would the majority of us on here. So from the marketing standpoint it makes no sense to have comparable power outputs for the baby and big sis...

Spot on... great reply and logic. Why spend close to 30k more for an E-class AMG if the C-class AMG has the same engine, for more space? I think not.

scovit

510 hp? Wow what a kick! In a C? Where's the order form? They will probably tone down the C fort mktg purposes

But I agree. E55 is a straight line beast but doesn't even come close in the handling dept to the C55. Drove them both before getting the C55. The E55 forum talks about problems w/ the E55, many of which talk about Kompressor and hesitation problems. The 6.3 naturally aspirated powerplant would take care of that.

It is always my choice to go w/ a same hp reg aspirated engine vs. supercharged, etc. So the 6.3 liter fills that bill.

Jack, I just got my new C55 and now I'm going to have to go back to the dealer and get on the wait list for a C63. THANKS!!!

BenzoAMGpower

I assume that the W204 AMG C-class will get the N/A version of this motor and the newer E and SL classes will get a twin turbo version of this motor!!! Just my assumption.

cntlaw

Very true.

There is no point to make a little brother to compete with a big brother.
i.e. C63 vs E63
And, there is no reason for MB to produce a car to be
significantly more expensive than its competitor! e.g. C55 vs M3
i.e. the more power you put in the car, more extra cost to strengthen the car for safety and handling.

Even so , eventually C55 becomes a C63 , it will still be a 400-420hp engine
enough to match/beat coming M3/4(E90).

What i observe, MB is indeed going into a engine power battle with BMW
M3 gets ~340hp , C55 gets 367hp
New 330i gets ~258hp , the 2007 C350 gets 268hp
And, the war begins with the facelift 7 and the coming new S
745i gets 333hp and S500 gets 306hp
750i gets ~350hp and S500(550) will get ~380hp

I believe the new engine for E55(E63) will be slightly more powerful
than the M5 i.e ~ 520hp 6.3 litre 4-Valve 7 or 8 G tranny :p

AMGod

The new V8 four door M3 is due to debut. Methinks, Mercedes will up the ante a bit. Having had both an E55 and an RS6 in the past; there is a market for a 3500 lb Sport sedan with 400+ HP. Got rid of both because of the boat factor. New C? I'm all in on that.

Sphinx

It looks very clean maybe down the road.

EKaru

That will never happen... The 6.3 makes 510hp in normally aspirated form which is more than enough.. A twin turbo would have what? 750-800hp... This is what will happen.... There will be an E/S/SL/CL63 making 510hp or so and a higher output 5.5 liter going in the new C55 making in the low 400hp range (possibly DOHC config)...
Eric...

Fikse

I think it's possible.... MB did it before.... the 2002 C32 AMG was just as quick if not quicker than the 2002 E55......

If the new C comes in with 450+HP, I'll be in line for one...

BenzoAMGpower

if the C63 does in fact come out and has over 450hp stock, then you'll see my C32 up for sale!!!!

Well, according to a 7/18/2005 article in germancarfans.com, the 2008 (see picture) C-Class will have a "55" with horsepower increased to the 400-410 range. There is no mention of a "63" for the "C".

scovit

Honestly, that sounds about right. Why blow the C-AMG load all at once? 400-425 HP makes sense competing with BMW and Audi.

BenzoAMGpower

an all motor 5.4L M113 making over 400hp n/a? Thats a little hard to acheive if you ask me considering how simple the design of that motor is. Keep the M113 on boost and the high compression to the modular motors.

MercedeSC32

where do you guys think one can get that bumper?!

EKaru

"Stuttgart’s new M272 naturally-aspirated 24-valve V6 engine family will supply 204bhp 2.5-, 231bhp 3.0- and 272bhp 3.5-litre powerplants for the C-class. At the top of the line-up will be an AMG flagship, expected to retain the existing car’s 5.4-litre V8, but with a power output up from today’s 367bhp to around 410bhp."

BenzoAMGpower

its hard to beleive but if its true then i would love to see what changes they made to a 5.4L M113 to put out over 400hp!!! I am actually more interested in knowing how much torque it gained!!
