Updated: S63 AMG will be the 1st to get the turbo treatment (5.5 V8 bi turbo)

Quote:
We're here in Affalterbach, Germany this morning for a Mercedes-Benz AMG tech day ahead of the Geneva Motor Show, and while we have yet to get a tour of the facilities, we already have some news – the 2011 S63 AMG will receive the company's all-new 5.5-liter bi-turbo V8 engine, as well as the SpeedShift MCT seven-speed gearbox already on offer in the E63 and SL63.

Even though it's down on displacement compared to the outgoing 6.2-liter engine, the M 157 generates more power (544 horsepower in 'standard' mode, 571 with the optional performance package) and more torque (586 pound-feet or 660 lb-ft. with the optional performance pack). And despite the change in engine size, the big sedan's S63 moniker will remain.

571/660 with performance pkg is .

The S63 is still one of my favorite MB's.

Just released...

Mercedes-Benz’s AMG performance division unveiled its new twin-turbo, direct-injection V-8 engine today in the S63 AMG Showcar, at its headquarters in rural Affalterbach, in the hills outside Stuttgart.

The new V-8, code-named M157, is based on the existing 5.5-liter V-8 (M273) that’s widely available throughout the Mercedes lineup. It will make its debut this fall in the S63 AMG and in the all-new, next-generation CL coupe, presumably as the CL63 AMG. Yes, that’s right: the badging will remain S63 even though the displacement will be 5.5 liters. But, really, what does that matter? Even the current AMG V-8, the M156, is actually a 6.2-liter, not a 6.3-liter, so Mercedes is just continuing its illogical badging because it wants to evoke the glories of the historic 6.3 badge.

Friedrich Eichler, head of powertrain development for AMG, explains that the new twin-turbo engine is actually rather conventional in design. “We use one turbo per cylinder bank and [rely on] very, very good volumetric efficiency [to prevent turbo lag] We also made the turbo diameter as small as possible.”

Eichler elaborates on the many changes made to the base V-8 for this new AMG application: “We changed the crankcase and a lot of geometric parts. Structural stiffness is improved, especially in the area where the crankshaft is rotating, where we made the ventilation holes smaller, for more rigidity. We have also made huge efforts toward mechanical efficiency, to reduce friction. We have roller finger followers and we have changed the pistons, the connecting rods, the diameter of the crankshaft, and the bearings. We also have a better cooling system.”

The result is an engine that exceeds the performance of the existing 6.2-liter AMG V-8 (not to mention the S65's twin-turbocharged 5.9-liter V-12) while offering 25% better fuel efficiency. In base form, the M157 produces 536 hp and 590 lb-ft of torque; with the optional performance package, which Eichler says is the result simply of software tweaks, but ones that have been extensively tested, the M157 twin-turbo V-8 will provide 563 hp and 664 lb-ft of torque. Notably, the M157 will not be subject to the gas guzzler tax in the United States. “This engine is all about torque,” notes Eichler, and indeed the torque peak in the standard configuration is a plateau from 2100 rpm to about 4600 rpm. With the performance package, peak torque comes on at 2400 rpm and runs to about 3600 rpm.

The M157 will be mated to an updated version of the MCT 7-speed automatic transmission that debuted two years ago on the SL63 AMG. It features a wet clutch rather than torque converter. The S63 will start in second gear, with upshifts as soon as possible, in a further quest to save fuel. A standard stop/start function will also help fuel economy. AMG’s performance estimates are 4.5 seconds to 60 mph with the standard engine and 4.4 seconds with the performance package; these figures represent 1.1 to 1.2 seconds quicker times than those currently achieved by the existing S63 AMG.
The Mercedes-Benz AMG M157 twin-turbo direct-injection V-8 engine will, like all AMG engines, be built by a single mechanic at the Affalterbach facility by hand, following the AMG principle: one man, one engine.

The S63 AMG Showcar pictured here is simply a means of showcasing the new twin-turbo V-8, says Tobias Moers, AMG’s head of product development. It also mimics the Mercedes 6.3 racing sedan that put AMG on the performance-car map back in 1971, right down to the red paint and the decals. Don’t expect the S63 AMG Showcar’s 325-section rear wheels on the production car, but Moers says that the 5-spoke wheels are accurate in style.

No word on peak revs of this engine?

With peak power being produced at 5.500rpm one must assume that it's doubtful if it will reach much beyond 6.500rpm all out, so it's going to rely heavily on it's torque to help produce to undoubtably startling acceleration figures.

Fixed. Sorry, it's a pet peeve of mine.

Anyway, this engine looks like it's going to pack even more brute, unrelenting force than the already imposing NA 6.2L V8. The competition between the next gen BMW and Mercedes super saloons will be awesome to watch. The tuning potential is there as well, for both platforms.

Thanks for the fix, at work I usually have someone to check in over but for this forum I will have to rely on you if that's OK.

You'll need to add Audi and their new range of FI engines to this pending battle royal and with the soon to be released RS6 plus on it's way with over 600hp I would imagine over the next few months that Autobahn driving will be as interesting to watch as this season's F1.

I can only wish that they'll release the RS6 here in the States. M5 vs. E63 vs. RS6

So you see, AMG is also going to build their engines based on Mercedes engines, just so as RS does and M is going to do the same. I hope the next C AMG will not get this FI 5.5l V8 engine, but a FI 3.5l V6. If not I really wounder how Mercedes makes such light engines, it is said to weigh only 208 kg, yet it has such a large displacement.

That is nothing more than a tribute version in the above pics.
Did you actually think they would put those in an production S63 Levi?

Car is bad ass no doubt, but it seems they really have a problem with an identity crisis.

I mean S Class? Roll Cage? I dig it but wow its far from what the car was originally intended for .... Executive transportation?

THAT RED CAR WAS BUILT FOR SHOW/INTRODUCTION/TRIBUTE TO A PAST RACE CAR AND NOT PRODUCTION!!!!!!!!!





The showcar (above) pays tribute to an early AMG-powered 300 SEL that won its class and finished second overall at the 1971 24-hour race in Spa-Francorchamps.



sorry.

I would like to see some of those features incorporated into the actual S63 AMG, like the aggressively flared fenders, meaty tires, alcantara steering wheel and headliner, and piano black/carbon fiber trim.

I feel safe to say those should all be in the production car.

Alcantara may be an option as well as cf.

Standard with the performance pkg maybe.

Hmm, I'm hoping the opposite and stick that bad boy bi turbo V8 to the C63 AMG. 550hp or (500hp detuned) would be badass .
But I do agree with you as sticking a V6TT would be more logical.

I reckon Mercedes has sort of slipped & tripped in the engine game.

Forced induction is the way of the future if not for the sake of being Green, for the sake of efficiency.

Mercedes seemed to forget this when they dropped the C32 3.2L supercharged engine for the 5.5L then the 6.3L.

Oh well.. Like I tell my dad. They're only humans. They make mistakes too.
