The Mercedes-Benz E-Class is a range of executive cars manufactured by Mercedes-Benz in various engine and body configurations. Produced since September 1953, the E-Class falls as a midrange in the Mercedes line-up, and has been marketed worldwide across five generations.

^ Yes, looks like a coupling and rear lockers. 
An electromechanically controlled coupling connects the permanently driven rear axle variably to the front axle. The best possible torque distribution is calculated continuously according to the driving conditions and driver's input. The performance saloon can thus be driven in a continuously variable way from traction-oriented all-wheel drive to purely rear-wheel drive. Transitions are seamless and based on an elaborate matrix. In addition to traction and lateral dynamics, the all-wheel drive system also improves the longitudinal dynamics for even more powerful acceleration.
It is still possible to drift thanks to fully variable torque distribution. This is where drift mode, part of the standard specification for the E 63 S 4 MATIC+, comes into its own. This can be activated in the "Race" drive program using the shift paddles, provided that ESP® is deactivated and the transmission is in manual mode. When drift mode is activated, the E 63 S 4MATIC+ becomes a purely rear-wheel drive vehicle. Drift mode remains engaged until the driver deactivates it again.
Rear differential lock: optimal traction, including on the racetrack
To improve traction and vehicle dynamics the E 63 4MATIC+ has a mechanical rear differential lock and the E 63 S 4MATIC+ has an electronically controlled rear differential lock. Both differentials reduce the slip on the inside wheel when cornering, without control interventions in the braking system. This ensures that the driver is able to accelerate out of corners earlier and with more power thanks to the improved traction. The car remains more stable when braking from high speeds, and the limited-slip differential also improves traction when moving off. The greatest benefit of the electronic rear-axle limited-slip differential is the even more sensitive and proactive control, which pushes the thresholds higher and makes it even easier to drive at the vehicle's limits. To deliver optimum cooling, the housing of the limited-slip differential has additional cooling fins.
The three-stage ESP® with "ESP ON", "ESP SPORT Handling Mode" and "ESP OFF" settings works in perfect unison with the rear-axle limited-slip differential and AMG 4MATIC+ all-wheel drive system, and is optimally tuned to the outstanding dynamics.

Yes but, darling Wolfgang, this doesn't actually answer Max D's rather in-depth question:
So the centre differential is always present in any AWD solution and standard 4MATIC is no different.
^ This is the standard non-AMG differential and, I'm told, this has a 45:55 front to rear torque split ratio. From what I can see, this is a purely mechanical centre diff using a planetary gearset and clutches to apportion torque in the onset of wheel slip. Nevertheless, it is a mechanical unit with the torque split fixed in static conditions.
The previous AMG 4MATIC is said to have a more aggressive 33:67 torque split to the rear but, once again, I am of the belief that this a fixed, mechanically set, ratio when static.
This new 4MATIC+ talks of electro-mechanical suggesting that the torque split is electrically actuated and variable based on fancy programming. Over to you biggest guy - go hunt out that 4MATIC+ centre diff cutaway.

^ That might be a good question to ask Tobias Moers at the upcoming debut. In the meantime, we have this cutaway with fully variable torque distribution, just front and rear axle need to be reversed. Perhaps it helped to inspire AMG's new E63 S 4MATIC+?

MB uses a new system for their tailor made 4MATICs now, which may also be of interest in connection with the new E 63 S 4MATIC+. Was mentioned already in the S 600 thread a while back.
On the left the new 4MATIC module, tailor made for each model. With the 7G it used to be integrated with the transmission, thus offering fewer choices. For example in the standard E-Class it splits front/rear torque 45:55, and in the E 43 4MATIC AMG Performance 4MATIC 31:69, while it's supposed to be fully variable in the upcoming E 63 S 4MATIC+. The 4MATIC module attaches to the front of the 9G shown on the right.
Tailor made Mercedes-Benz 4MATICs. It's an older overview, from around 2012 or so.
The 9G.
The new torque converter of the 9G which can now supposedly take the humongous input torque of the V12. But for the E 63 S 4MATIC+ the wet clutch pack is used instead for faster response.

I cant see any different
Only the rims and the exhaust
And i cant see anything new between this and other amg classes like the c and s
The only new thing here its the black part next to biturbo
A visual treatment is in order than.
I think the differences are really noticeable! (thanks throughandthrough for the pic comparo.)
The front and profile of the E63 is far more aggressive than the sport-package.
The bulging hood line and reshaped shoulder line reminds me of pumped up biceps compared to the sport-package. It looks like its gone to the automotive gym and come back to pack a serious punch!
The performance numbers are insane.
0-100km/h (62.5mph) in 3.4 seconds. Most AMG models achieve a 0-60mph time 0.2-0.3 seconds faster than 62.5 by the magazines here in the US. When the car comes to our shores to get tested I would expect a nought to sixty around 3.1sec quite easily. it should hit 100mph in very little time.
This E63 might smack the Hellcat Charger in a good race. The Cadillac CTS-V is history
Faster than the historic Merc SLR? probably so. The SLR had an average 0-60 time of 3.5 seconds.
Mercedes SLR 0-60 MPH and Quarter Mile Times
YEAR MAKE, MODEL & TRIM 0-60 TIMES 1/4 MILE TIMES
2004 Mercedes SLR McLaren 3.50 sec 11.50 sec
2007 Mercedes SLR McLaren 722 Edition 3.40 sec 11.40 sec
2008 Mercedes SLR McLaren Roadster 3.70 sec TBD
2009 Mercedes SLR McLaren Stirling Moss Edition 3.40 sec TBD

Does anyone know if the electronically controlled diff use steering angle, G forces and throttle as inputs?

is there a reason or added benefit to why the front, especially the hood shut-lines, differs rather drastically from the non-AMG E-class?
