E Active Body Control




The active suspension also allows a very wide spread of handling characteristics that can be set with the driving mode – from the comfort of a luxury saloon to the agility of a sporty SUV. In addition the engineers have realised a number of new functions for the GLE:
• Rocking mode: If the GLE has become bogged down in a sand dune, for example, this mode - which is only available in the Offroad program - can help to free the vehicle more easily in many such situations. If possible the suspension level is automatically raised and lowered several times, thus alternately increasing and reducing the ground pressure of the tyres and improving traction – the GLE rocks itself free.
• Individual wheel actuation: Individual wheel actuation is another new function for off-road driving. After selecting the Offroad program, this allows the spring level at each wheel to be individually adjusted via the touchscreen of the media display, thus improving the vehicle's off-road attitude on rough terrain when e.g. one wheel is stuck in a ditch or a wheel spring is fully compressed.
• Rear-end lowering when loading/unloading: When the button for rear end lowering in the luggage compartment is pressed, the vehicle is lowered to a defined level at the rear axle. This allows the luggage compartment to be more conveniently loaded and unloaded. The level at the front axle remains unchanged. The rear axle is lowered by 40 mm from its currently set level, but not lower than -70 mm. This function is deactivated when a trailer is connected.
E-ACTIVE BODY CONTROL in the GLE also has functions already familiar from the S-Class, which have been improved further:
• Curve tilting function: In driving mode CURVE, the GLE actively leans into bends by up to 3° in three stages, like a motorcycle. This reduces the lateral forces acting on the occupants. Cornering is therefore made much more pleasant, especially for the front and passengers.
• ROAD SURFACE SCAN: If the GLE is equipped with a stereo multipurpose camera, this continuously monitors the road surface ahead of the vehicle. The suspension struts are then activated so as to substantially reduce the body movements when driving over surface undulations, as the suspension responds even before the uneven stretch is reached.
E-ACTIVE BODY CONTROL in the GLE supplements the air suspension with semi-supporting hydropneumatics. The air springs bear the base load of the vehicle body and gradually regulate the level. The hydropneumatics generate dynamic forces that overlay the air suspension forces, and actively support and dampen the vehicle body.
At each wheel, a damper is installed within the axle whose two working chambers have an adjustable damping valve and a hydraulic pressure reservoir. The damper is connected to an intelligent motor/pump unit in the 48 V network by hydraulic lines. Actuation of the motor/pump unit enables the hydraulic fluid to be displaced to create a difference in pressure within the damper, allowing an active force to be generated.
The motor/pump units at all four wheels are coordinated by a central control unit which also actuates the valves and the compressor for the air spring, and therefore always controls the entire suspension system. It was developed according to the safety standard ISO 26262.
The transition from a belt-driven hydraulic pump to an electric 48-volt pump also takes into account the increasing electrification of the powertrain: the combustion engine is idle increasingly often – or not used at all.
And finally, when optioning E-ACTIVE BODY CONTROL, DYNAMIC SELECT includes a Sport Plus (S+) mode that maximizes dynamism and engine/transmission response; ECO start/stop is deactivated. This mode is not available in any other configuration on the 350 or 450 without E-ACTIVE BODY CONTROL.
Greg and myself will post our thoughts on the real-world advantages of E-ABC as soon as our GLE 450's arrive. Stay tuned.




I meant dropping $8,100 on it on the GLE.

Wow, did not know they were discontinuing the coupe. When is the next gen S class coming out? Maybe a W222 is in my future....

The Best of Mercedes & AMG
Every review I've read or watched on YouTube pretty much says this suspension is off the charts amazing. And it's the only SUV in the world with this type of suspension so that's appealing for sure.
Car is for my wife and our upcoming baby. I think her and the baby will really appreciate the smooth ride from the E-ABC suspension.
When I'm driving, it will also allow me to drive a little more enthusiastically without the passengers feeling it as much. =)

"Total stabilization: AMG ACTIVE RIDE CONTROL
Redeveloped in Affalterbach, AMG ACTIVE RIDE CONTROL based on AIRMATIC forms the basis of a driving experience characterized by a high level of agility, neutral cornering behavior and optimal traction. A new feature makes a significant contribution to the AMG-specific tuning for high levels of driving dynamics: the active roll stabilization with two electro-mechanical actuators working independently of one another on the front and rear axle, as well as fully variable torque distribution.
Not only does the system reduce rolling movements when cornering, it also enables more precise tuning of cornering and load changes. In addition, it increases driving comfort when driving straight ahead. Movements in the body can be actively and optimally adjusted to driving conditions.
Air suspension with continuously adjustable damping
The AMG ACTIVE RIDE CONTROL based on AIRMATIC with particularly sporty spring/damper set-up, including adaptive adjustable damping ADS+ (Adaptive Damping System), combines outstanding driving dynamics with high ride comfort. The damping characteristics can be pre-selected in three modes, "Comfort", "Sport" and "Sport+", allowing a significantly more noticeable differentiation between excellent long-distance comfort and sporty driving dynamics. In addition, there are two new levels for off-road use - "Trail" and "Sand".
Thanks to pneumatic self-levelling at the front and rear axle, the GLE 53 maintains a constant ride height regardless of the vehicle load. The vehicle level is generally lowered by 15 mm in the AMG DYNAMIC SELECT drive programs "Sport" and "Sport+". In the "Comfort" drive program, the vehicle is lowered by 15 mm from a speed of 75 mph. This reduces aerodynamic drag and, in turn, fuel consumption. In addition, handling stability improves thanks to a lower center of gravity. In order to increase the ground clearance on poor road surfaces or on ramps, the vehicle body level can be raised by up to 55 mm at the touch of a button with the engine running – both with the car stationary and in motion."

Considering I haven't heard anything on this forum yet (and usually the U.S. guys get the cars first), I'm not very confident of the quoted timelines.
Thank you
S-Class ABC/MBC is a hydraulic system that constantly changes damping within milliseconds, based on sensors that relay information about body attitude. The MBC version uses cameras to include information about road imperfections it's about to encounter. Like noise-cancelling headphones, the hydraulics apply motions to counteract forces acting on the body. It does an amazing job of smoothing out the ride. On my S65, it also seemed to defy the laws of physics in taming body roll and understeer with the massive V-12 up front. The E-Class ABC, even in AMG tune on the E63S, doesn't come close. On the other hand, the E is so much more fun to drive. The magic-carpet ride of MBC isn't about driver's feedback.
As has been mentioned, AWD is such an important part of the automotive experience now that it's a near-fatal flaw of ActiveBC/MBC that it can't be installed in AWD cars. It operates on four wheels, but there are physical limitations that prevent it from working with 4Matic.




It's a francophone website; the video has no voice-over, as it appears to be a B-Roll video footage making it universal.
At one point you will see a side by side comparison of a GLS with E-ABC and another without. What a difference it makes.
