MB plays a different market stratagy. Others can play along if thay like!

haha if you say

Looks like Autoweek believes the Kompressor V8 in the SL55 will be replaced
by the Bi-Turbo M157 unit in the SL63.

The project was terminated a while ago. There is just no place for this engine in the AMG lineup.

No more Bi-Turbo V8?
My guess is that MB will offer it first in the S63 (maybe the facelifted w221, but I doubt we'll wait that long), then the CL63 (new CL of course). But I'm not sure about the SL63. I think MB will wait for the next generation SL.
I mean, why give the SL55 a boost with the facelift and not introduce the SL63?

Sorry, but I have to say that a turbo V8 makes sense and is the only logical way to increase performance of the SL/CL/S "63" models over the previous "55" models. The naturally aspirated 6.2L V8 has virtually the same hp 500 vs 515 as the old SC V8 and way less torque. Even with seven gears it won't match the old SC V8 models with the increased weight of the W221 S-Class. A turbo is the only logical way to go. It is torque that moves these larger/heavier cars, not hp. Sure there is a 580hp version of the new 6.2L V8 that is naturally aspirated, but that is more for a sports car not a sedan/coupe/roadster.

Yep, I agree with that Merc1, however bum-man says the project wa terminated a while ago.


Bum-man, do you have any sourses to back this claim?

Bum-man, remember this thread? AMG boss announced: "for the future, the trend will be turbocharging"
This thread was created in January 9th 2006!!

The next variant of the 6.2L V8 will be a turbocharged version. BMW's head guy just make some comments about the the S63 being "firebreathing" and 515hp and 465lb-ft of torque aren't "firebreathing" in a 4400lb sedan, but 575hp and 600lb-ft of torque are!

Thats dead on with the link I posted in this thread. It describes the
Fire New! AMG M157 Bi-Turbo V8 that will debut in the S63 next January!

Im wondering what transmission MB will mate with this engine.
I hope it`s something new.

Hehe

There have been several articles saying that the M157 was stopped because of budgets, it was supposed to be another engine designed and built entirely by AMG.
Just looking at the rumored numbers, the engine would be filling in a gap that does not need to be filled. It would be performing too closely to the V12 and the 55k. So, unless Mercedes plans to discontinue the newly revised 55k and the young V12 then I guess I have to assume they will be introducing something within the year. But I don't think that will happen, at least not for a few more years.

We will see how MB plays the cards out. That article is still fresh!
I don`t think the boss would make changes or terminate the Bi-Turbo V8
overnight.

They'll do the turbo V8 with 570hp and bump the V12s up to 650 hp. Watch and see.

Oh my!! according to this thread it sounds like we will get two versions
of the M157 Bi-Turbo V8!! This info is from the May issue of CAR magazine!

"Hammer1" is a supposed light pressure turbo. (571hp/ 664lb-ft)
"Hammer2" is supposed to have higher boost pressure! (707hp/ 737lb-ft)

If Hammer2 gets that much power the M275 Bi-Turbo V12 used in the S65 AMG might be discontinued! and go with this Hammer2 (unless AMG is preparing a 800hp V12 )

Thay also say the C63 will be introduced with the M156 n/a V8 but with
450hp, down from the CLKs` 481hp.

LOL..this is crazy..well lets wait and see..my god..im gonna check with my AMG contact.. or actually with ben sulayem.. and then he can check with his AMG contact

lOl, that sounds like the thing to do.

I hate to see the V12 go I wonder whats going to happen to it in the near
furure!

Nice info man, sounds very promising.

the V12 wont go.. it will surely be upgraded..they still need to make it for the new paganis.. and to keep an huge edge on the others..

No problem.


Artist, you might be right! I remember reading a rumer about a 6.8liter DOHC
V-12 in the works for MB. This might be an AMG engine exclusive as well, but man!! what kind of nubers are we going to see from this thing!!

This is really getting insane!

LOL.. i say if you can make it work.. with new gearboxes and chassis that can handle the power..then bring it on..

I believe we might also see the new SMG type transmissions the AMG boss promised maby when the S63 omes out. I like the 5-speed but I think it`s starting to show it`s age.

well the SMG type will be out i dont know when..
but i think it will be based on the 7G tronic.. and that SLK SLR.. from dubai uses the 7G and it has like extreme torque.. so the gearbox can handle it with some mods.. mb are just being secretive

puuh I can breath again (if its true)

why down.. if CLK can have 481 then let the C to..

so the CLK63 can be a more exclusive car?
