I've been suggesting it in some other threads but to make it official ...

I would really like to see electronic differ in LFS. Both on RWD and 4WD cars. I've been reading about it quite a lot and seeing it in action and its very impressive. The most famous representative is Mitsubishi Evo VIII and currently IX with 4WD and intelligent power distribution on wheels that have enough grip to handle the power. If someone dont know what Im talking about just look at Top Gear review http://video.google.com/videoplay?docid=5639412376935133899

The same one only controlling rear wheels is present in Ferrari F430. It doesnt mean the car is easy to drive. Its no traction control. Its just another better way of distributing power.

There are suggestions of making some WRC-style tracks and cars. Maybe tracks are not that good idea but new 4WD with high power and this diff would be terrific on rallycross tracks. Just like Evo XIII. Good track car and good WRC car. I know - there are changes between these 2 but WRC cars have such differ. Almost all of them.

It should be customisable of couse is certain extent.

Forseeing some discusion:
LFS is a racing-sim. If this feature is available in racing then why shouldnt it be implemented.

maybe it will be included with the so-called "rally pack" people talk about....

Weren't the active locks disallowed in rallying (WRC) in this season?...
What kind differentials do they use in the GTRs in fia-gt and such...?

Clutch packs as far as I know.

Few people are about to jump out and say they want 'driver aids' and I agree with them, for the cars we already have at least. I'd be intrested to see some of these features simulated but only after the basic physics model has its biggest flaws sorted.
