I've had 2 E-LSD cars, f type and m4

Both cars I wasn't keen and wished they had a mechanical lsd

Hows the edif on the c63 s?

Im not interested to set lap times in this car so not interested in the improved traction argument - sliding the rear out and "hoonining" would be the idea

 

What specifically were you not keen about and what are you looking for with your question? Also what year are you considering? The e-diff in the C63S is highly adjustable based on the driving mode, AMG Dynamics and the traction control system. The 2019 C63S comes with the 9-stage traction control system from the AMG GT R, so you have an immense freedom of how much grip vs slip you wanna have on the rear wheels for hooning around. The e-diff, engine torque etc. gets adjusted accordingly based on the chosen settings. The C63 with all the torque it has, has never been an issue to hoon and slide around. On the contrary, traction has been its mortal achilles heel, so the e-diff, traction control etc. helps to reign in the horses when you need/want traction and that's been the major focus for all the changes in the 2019 facelift. I would say the unique thing compared to others with the 2019s is the level of adjustability that is offered. The M4 and others generally offer a relaxed stability control mode, BMW in the M models calls it MDM, MB/AMG calls it Sport handling mode, so these modes allow for more slip than the standard setting, but the 2019 C63S takes it much further with the ability to turn off stability control and then dial down traction control from fully on to fully off in 9 stages.

 

Thanks for your reply - yes the 9 stage traction control is awesome but not what im asking (currently looking at a 2017 car)

My issues with the e-lsd is low speeds drifting just felt unstable and twitchy and to get the car feeling settleed, speeds really had to be much higher - this doesnt make a great hoon car imo. In compariosn my older m cars would feel planted an predictable with their mechanical locking diff

 

Thanks for your reply
The issues I had with the E-LSD was that at low speeds drift they felt twitchy and unstable - my theory was you could feel the power being sent to different rear wheels as the ecu wanted
Older M cars ive never had this problems with a mechanical LSD
The only time the ELSD felt at home and stable was at much higher speeds on a track
Yes the 9 stage traction is awesome - Im looking at a 2017 model (latest thought is a new c43 depending how "real" these youtube drifting videos are

 

You are the first person I've come across who voices concerns about these modern active differentials in this way. I haven't heard any complaints about the C63S e-diff so far. On the contrary, even highly skilled drivers report that the systems in the C63S work with them and not against them. My only experience so far with active rear differentials is the one in my current '13 RS5 and it has done wonders to the driving dynamics on this AWD platform. I'm not exactly going drifting in the RS5, but as opposed to my previous Audis, this one actually does go sideways if I want to and I've never felt the diff to work against me. My main concern coming from high powered AWD Audis going into C63S ownership is traction and the ability to actually put down the power the car has and the enhancements in the 2019 are so far very promising. It'll never have AWD traction of course. If you are all about drifting, I'm not sure a C43 with AWD is the way to go. Yes, it can go sideways, just like my Audi can go sideways, but ultimately the front wheels are gonna pull you straight again. You can take any car sideways with a Scandinavian flick pretty much, and that's what it looks like is how folks are drifting the C43.

 

With my 2018, low speed maneuvering (90 degree right turns from a stop, like at a stop sign), especially in Sport+ mode, can feel a bit twitchy. I think it's a combination of factors - wide track, somewhat wide rear tire, and maybe aggressive differential. Feels like the inside tire is spinning. It's not noticeable in Comfort mode (but Comfort starts in 2nd whereas the other modes start in 1st) and not really a problem in any mode as long as you are smooth with the throttle from a takeoff. It seems like something that could be improved with rear-wheel steering (which the GT R has) but doubt we'll see that in a C-class.

 

I think the problem is when you straighten the wheel the ecu doesn't know what to do with the diff and the car freaks out
Ive been looking at a S car that has a ll the spec I want other than the e-diff
