Active M Differential
Appears the M2 is getting the Active M Differential. While I can't say I like the complexity with sensors and processing (what happens when a sensor breaks?) I do wonder how this will change real world driving. Does this mean we'll get improved traction on snow and ice?

Typically it changes the locking amount of the diff looking at the steering angle and car angle and traction on each tire.
Yes it may help with traction on bad roads. If you are looking for easy to repair I wouldn't be looking at electronic differentials. Last edited by HawkZ4M; 10-16-2015 at 06:18 PM.. |

Given a choice, I would choose something simpler. This also applies to rain sensing wipers and nav systems I don't need. However, I was not consulted on this particular model.
The point is.. this doesn't work like a mechanical differential it may offer some unique benefits across a broader range of circumstances. These are already available in other models. I've read the interviews with designers but haven't seen much real world experience reflected in various forums. Any insights? |

Anyone have any links to some good tech info on this diff? I'd be interested in learning more about it, and understanding how it's different from standard clutch LSDs that I've come to know and love... |

So as suspected, this differential is a fully functional mechanical clutch LSD, but with the addition of sensors and electronic motors to affect how lock-up is applied in reaction to (and proactively, based on) various factors. In terms of what happens if the sensors/motors fail...my guess would be that it will still function as a standard "passive" LSD without the proactive/enhanced inputs from the M gadgetry.

http://f80.bimmerpost.com/forums/sho....php?t=1015603 The differential section starts on page 52. This is shared tech from the current M6/ M5/ M4/ M3. You will also find details about systems shared on the M2 including DTC, front & rear suspension, servotronic steering, etc. |
