I'm surprised that MB is throwing in the new engine before the W212's lifecycle is over. At the same time, I guess that shouldn't be a surprise given that M156 was thrown in the W211 E63 towards the end, too.
It feels as if the M157 was a "filler" engine while waiting for the development of 4.0L as the second engine designed from the ground up by AMG.

Interesting

I doubt it'll perform significantly better than the current iteration e63 with the m157... However I bet the trans and throttle will be improved and it'll definitely be lighter of all else stays essentially the same

Curious what the final product will look like

Please consider a CPO profit margins are compares to a brand new car. Also the body style preference and you might get your answer.

W212 cycle is over. This "2016" is W213. Why else would it be wearing camouflage.

PeterUbers

Yup ... This is a U.S. 2017, European 2016

So the 5.5tt has its advantages ?

JoeNobody

The 5.5TT still has better tuning output than the 4.0, so they'll probably close the gap by improving other aspects of the car.

They'll probably add a dual clutch transmission (like the new W222 S65 has), the same electronic LSD as C63, and maybe a diff on the front wheels too.

Of course - more displacement and it is a proven engine. I think the new engine will have to make a lot more boost to reach the same output. But as others have said, I would expect the new E63] to be just as fast based on improves in the drivetrain and weight loss.

KarlG

Almost for sure, the new top AMG E, if it has the 4L TT, will have at least the same hp HP and higher torque compared to the previous 6.3 and 5.5. It will also have higher MPG.

That is just how they tend to roll.

otakki

Yes, the new camo'ed car does have different shape and side mirrors. It's just hard to fathom what the hp/tq curves will be like when looking at the specs from C63S and GTS. Obviously, the E63 will have to have higher engine figures than C63. However, will E63's figures be allowed to be better than the GTS, which is priced higher and now considered one of the flagships.

OrientBlue3

If this it true, it would make perfect sense. There are rumors that it is a strong motor and can handle quit a bit more power than the current C63 S output is putting down. That would be validated if you've been reading about what Eurocharged is getting out of the 4.0 TT motors during their initial testing.

I for one would love to see all the bigger Merc AMG's get the smaller motor to reduce weight. The e63S could be a beast if it could shed some weight up front and get much better MPG in the process.

S65 and all MB V12s absolutely do not have a DCT. The only MB with DCT (in the US) are all CLA/GLA, SLS, and GT/S. The reason being is DCT cannot often times handle the torque (with our current tech) that is pumped out of the V12 engines and M157s.

This new 4.0TT V8 motor seems to have more tuneability relative to the M157 5.5TT V8. You can get the 4.0 boost pretty high and the numbers should in theory be double that of the CLA45 since it's two of those motors put together.

PeterUbers

Once again we should consider that audi has had a 4.0tt for a while in the rs7 and its nuts in stock form and it's tunability is also pretty amazing

JoeNobody

Car and Driver reported the new S65 has a dual clutch. Maybe that's just a misprint

Good point. I drove one and it's a great car indeed. Quite the looker too.

AHI

Needs dual clutch.

The new E63 partial camouflage.

Seems like the classes of M Benz are looking all too similar.
Take your pick - small C, medium E or Large S.
:/

60nomad

All I can say is that from 2003-2006 = Great motor
2007-2010 = junk motor
2011- present = great motor


Trend says that the 4.0 with lots of power will be junk!

JoeNobody

4.0TT has fully forged intervals. It should take a lot of boost well

TheOtherEric

If they're putting the same motor in the C63 and E63, it sounds like they're giving up on the idea of having the E63 faster than the C63. Even if they bump the boost up a bit, it won't be enough to overcome the huge weight increase of an E63 (vs. C63).

And I'd be surprised if the new E63 with 4.0TT is as fast as our 2014-2016 with 5.5L. Granted, AMG doesn't normally make the E63 slower than the outgoing model, but this may be the exception. They'd have to lose a LOT of weight.

From MBUSA:

"The 7-speed AMG SPEEDSHIFT PLUS transmission offers the driver three selectable modes: Controlled Efficiency features a fuel-saving ECO Start/Stop function. Sport mode raises the shift points and reduces shift times by 30%. The paddle-shifted Manual mode offers lightning-quick 100-millisecond shifts and maintains the selected gear at full throttle or upon reaching the redline. And both the Sport and Manual modes offer 100-millisecond upshifts and rev-matched downshifts."

Unfortunately, no DCT.

nstanford99

^^^^ well it could be like the 03-06 E55 vs the 07 and up E63. The E55 was arguably faster than the NA E63 i think! drove the 63 a while back while having my old E55 and wasnt impressed!

PeterUbers

So how can the BMW M5 have a DCT transmission that can handle all that torque that it produces yet the Mercedes cannot accommodate a DCT with its torque?

looney100

I don't think that anyone is saying that NO DCT can handle that kind of torque, more so that the DCT that MB has can't handle that torque. There are a few exotics out there making lots of torque using DCTs - just not Mercedes.

otakki

Maybe the aim for durability. For example, the same DCT is found in SLS and Ferrari California, but Ferrari tuned it for speed, whereas MB tuned it for durability. So far MB has been known to be more reliable than BMW's.
MB probably needs to develop a new unit. It's not impossible for DCT to handle lots of torque. Just look at the DCT in the Veyron.
