Breaking News: New twin-turbo 5.5l V8 for S63 AMG

[bum-man]

Had another picture of the W108 AMG in my photo album, check out the flared rear fender looks familiar.

While it has different mounting points, the engine, code-named M157, still fits inside the current S-, SL- and ML-Class bodies, though AMG has yet to confirm whether it will nestle comfortably in smaller cars.

It avoids many of the more modern tweaks, like variable compression turbochargers and, instead, uses one Garrett-Honeywell turbo per bank (running at up to 1.3 Bar of pressure), combined with a clever, in-house air-to-liquid intercooler capable of dropping air inlet temperatures by 90 degrees Celsius. It also runs incredibly high compression, with AMG claiming it runs at 10:1.

While AMG denies the passenger car range will adopt all-wheel drive to cope with the biturbo’s tremendous torque outputs, so the initial versions will remain rear-wheel drive, punching through a new version of the seven-speed, wet-clutch automatic.

‘We’ve gone for very good response and driveability with the biturbo,’ AMG’s head of drivetrain development, Freddy Eichler, insisted.

‘There’s no cross-flow in the turbos, like some, and they are not variable vane. They are just to our specifications and they work well.’

Developed out of the new M278 4.6-litre V8 from parent company, Mercedes-Benz, it shares the bore centres and bank angle, but little else in terms of hardware. Its block, sump and cylinder head are different, while AMG also welds the exhaust manifold to the turbo-charger housing.

Impressive numbers. Hopefully all that torque doesn't upset the fine handling AMG achieved with E63.

Mercedes has been building a strong product lineup over the last 3 years and this shows that they are dedicated to maintaining this trend. AMG has been particularly on point for Mercedes. They have managed to successfully shed their image of simply dropping powerful engines into regular Mercedes vehicles and calling it a day. The C63 and E63 are both extremely well-sorted sports sedans on par or better than any offerings from BMW's Motorsports division.
Helping in this turnaround is that fact that I think BMW's recent products have not been particularly strong (X5 & X6 M, F10 5 series, 5 series GT & Z4). While BMW experienced huge growth over the last decade, it has become increasingly apparent that BMW has stretched themselves too thin in an effort to maintain and further increase market share. I can't think of any car in the Motorsport lineup that I would take over today's AMG equivalent. Keep in mind, I currently own an e60 M5.

I would like to avoid turning this thread into a BMW vs Mercedes yelling match so if anyone would like to have a serious discussion about the direction of these brands and their respective performance divisions, I would recommend starting a new thread.

PS I hope the flared fenders make it to the regular production version.

Hmmm, if you really didn't want to make into BMW vs MB, you should have probably not brought BMW into this thread in the first place before asking others not to.

And sorry, M3 is still dynamically superior to C63.

That is HUGE! Keepin' it simple I like that.

What are you talking about?? We don't even know about the M1 engine, your M5 numbers are pure speculation.

Those were the Autocar numbers realised a month ago. At theast the PS numer was almost comfirmed by SCOTT (remeber his post saying the F10 M5 would have almost 580hp) and S´pymp (or whatever). So I´ve suposed the numbers are realistic.

It appears that they might sell both the 5.5 and the 6.2 engine for a while according to some other sites. I think the E, C and the smaller cars should keep the sportier n/a unit....at least for a while longer. The C63 will no doubt keep its same engine until facelift time for 2011-12. CLS will no doubt get the new 5.5., but what about the 2011 E63 here in the U.S. So many new questions now what we know what the new engine is!

^Yea I would like to see the E63 AMG stay with the same engine and CLS get the new one. Make better sense and gives the CLS AMG more of a selling point. I also remember hearing that the SLS will keep the engine it has for now. Probably just the S, S-coupe and CLS for now and then the rest.

 

[Zafiro]

so its only Audi left now then?

so its only Audi left now then?

Left for what? big turbo charged engines? You forgetting the 580HP TT V10?

They say the RS5 is the last N/A engine from Audi. Soon its only Turbos just like Benz and BMW.

The specs of the new engine are porn to an enthusiast's ears. And, the coupling of such a well-sorted engine to the MCT is indicative that the era of compromises is over, comprmosises such as mating a great engine to an old transmission because of lack of torque capacity.

I think the performance package will be more expensive now than the circa $12,000US that it is now, but I still believe it is worth it so long as it does not reach or exceed $20,000. If it does, I hope it includes an upgrade on wheel and tire package, in the manner of the rubber of this show car. Although, it requires some bodywork modification of a Black-Series nature.

Either way, having a 63 AMG car that can pull off 22mpg is almost too good to think about. Further more, especially the PP edition makes the S600 almost irrelevant (interior quality still standing) and may make the S65 with its aging 3-valve V12 a proposition that is harder to justify.

The rumored 707hp version of this V8TT may end up being labeled Performance Package Plus. It is sacrilege to be asking for more performance, especially so soon after the release, but what the hay! Next Black Series SL anyone?

 

[Cashmere]

900 NM Now that is beyond INSANE!! This is going to be an absolute sledge hammer. Will they revert the badging back to S55 ?

 

[Batoussai]

Christ, the explotation of tires will be expensive on this car one good run and we have slicks

 

[HighestOfHigh]

So far that old article has been completely correct so expect a 707 hp 1200 Nm engine for the V12 replacement.

....Man I would love that!

Will they revert the badging back to S55 ?

Seems like it will stay the S63 AMG.

 

[Pagani]

I have a feeling it wont require a V12 for the 707hp/1200nm mentioned in that article. Instead, a 1.5 or 1.7bar version of this V8 that was revealed today.

It sounds like it will be the same unit with larger turbos. Also keep in mind the article is like 3-4 years old.

Interestingly enough, the 2011 SL has just gone on sale, but there is no SL600 listed for the U.S. market. I wonder why. Could be that it was just dropped due to poor sales.

As for the name S63 AMG, the number now has virtually nothing to do with the engine's displacement. Both the naturally aspirated 6.2-liter and the new bi-turbo 5.5 will wear the "63" name. And no, the 6.2 liter is not going away. Eichler says the engine's characteristics better fit the SLS AMG's personality. He hinted it's unlikely the engine will be swapped out any time soon in the new E63 AMG.

Two other tasty tidbits emerged from Monday's AMG reveal. One is that Mercedes' tuner is working on some sort of new engine technology internal to the engine that will be ready mid-decade. Eichler and Mornhinweg were tight-lipped on any specific details, other than the technology will be found under the hood, and not elsewhere on the car.

And AMG plans to go sub-C-Class in size, according to Mornhinweg. "We expect from our step into the compact class segment not only profound impulses within the AMG fleet consumption, but also the opening of a new group of customers."

Oh my... Speechless.

I agree, they definitely need to re badge it a 55 to differentiate it from the 63.

Oh and it looks like it will make it to the S-Coupe first since the spy shots show the same exhaust tips.
