@WazzupEngKU Except the Audi Sport diff is less advanced, the SH-AWD system can transfer 100% of the torque across the rear axle to one wheel and uses an acceleration device to overdrive the rear wheels up to 5.7% over the front.
@gazboselectamo - this system can put 100% of the rear torque at one wheel. what is so different? The Acura system can only put 70% of overall torque to the rear wheels.... while this one can put 85%...
@WazzupEngKU Honda's synthetic handling 'awd' is a crutch for the front wheel drive platform.
Look at the weight distribution in the TL 59/41 (58/42 with the stick)
Honda decided the best way was to not drive the inner wheel in a turn (3 wheel drive), and they accomplished that with two separate clutches (one for each axleshaft), there is no rear or center differential.
@TransAmDrifter They've switched to this crown gear and clutch pack setup so they can transfer more of the torque as a torsen is limited to a specific range. The RS5 even swaps the centre diff for one of these, essentially 2 sports diffs, one for the centre split and one for rear. It worked for mitsubishi for years (AYC), although they switched to a planetary gearset so they could transfer even more torque across the axle (as does the Acura/Honda SH-AWD system).
@gazboselectamo - meant the crown gear system can put 85% at the rear... and up to 70% up front... that is a greater range than the Sh-awd (which is also a very good system).
@Amidat I hadn't read any figures to indicate how much torque the audi system could transfer across the rear but you're right about the centre diff being more rear biased although I'm not too sure how important that is. Both systems are very good but I think it's important to note that Mitsubishi have been doing this for years (15yrs+ in fact).
@Amidat The R8 handles so well already because of the weight distribution but I agree an R8 with sport diff would be very nice! As for why their not standard, typical Audi penny pinching I'm afraid. If they think they can squeeze more out of their customers they will!
@gazboselectamo - well i know that the R8 usues a viscous coupling... so maybe there is nothing compatible. I knew the new Lambo switched to a Haldex system... so we'll see what Audi does on the new R8. Haldex does make a similar type system... though not as effective. I know when asked why the RS3 didn't have it they said the cost would be prohibitive... but the R8 and all Lamborghini's are over 6 figures... so this should be interesting.
@Amidat Personally I think the cost issue is a bit of BS as a Mitsubishi Evo costs less than an RS3 and features an arguably more advanced torque vectoring active diff setup. I think it's more to do with keeping each respective model in it's place - for instance no sports diff on TT-RS as it would be far too close in performance to the twice as expensive R8 for Audi's comfort!
@gazboselectamo - of course market position has something to do with it. Remember though that Mitsubishi is a huge manufacturer (not just cars)... Also remember that Audi's are luxury cars...and Evo is not... so the markets are different. Mitsubishi certainly gets big credit for it's yaw control system... that's without dispute. The market segments are different though... so have different demands.

If i steer right with this cat , the right wheel looses power by that clutch and the left one gets more from that little electric engine ?

Gazbo, sport diff standard on an RS5! I cannot wait to use it when I pick mine up. Oh yeah

I think, It really looks like SH-AWD System From ACURA!!!

I love quattro, but I hate electrification... old torsens were fully mechanical and no one complained.

Sport differential is an optional... a very good optional :D

on the more expensive models - why isn't this standard? I also wonder if the R8 would get this....?
