I found this while browsing germancarfans.com

"At the heart of the quattro system is an electronically controlled and hydraulically operated multi-plate clutch, which now works even faster than ever thanks to a new pressure reservoir. If required, all of the drive force can be redirected from the front to the rear wheels within a matter of milliseconds. To make allowance for the high torques produced by the TFSI engine in the TTS, the drive train has been reinforced as required."

So I think the Haldex AWD in previous 2nd generation TTs(3.2 quottro) can only transfer torque up to 50:50(front:rear) max.

Where as now with TTS, torque can be transfer 100% to the rear?!

Also,according to Haldex's website, 2nd generation TTs should be using their 4th Generation of Haldex AWD system.<ul><li><a href="http://www.worldcarfans.com/9080111.003/page2/official-audi-tts-revealed-ahead-of-naias-debut">http://www.worldcarfans.com/9080111.003/page2/official-audi-tts-revealed-ahead-of-naias-debut</a</li></ul>

"The 2009 model TT's (with quattro) has gotten the 4. gen Haldex system, which is a major upgrade from the 2. gen that you find in older models of the Mk2 TT's (3.2) and Mk1 TT's.

The big differense is that the 1. to 3. gen is a reactive system (reacts after wheelspinn), and the 4. gen is a proactive system (reacts continusly on throttle and steering input - which is before any wheelspinn)."<ul><li><a href="http://www.tt-forum.co.uk/forum/viewtopic.php?f=19&amp;t=127531&amp;sid=9de954865f ad38d3c47d6d16ef0aba68">http://www.tt-forum.co.uk/forum/viewtopic.php?f=19&amp;t=127531&amp;sid=9de954865f ad38d3c47d6d16ef0aba68</a</li></ul>

It's also capable of 94%-2%-2%-2%.

joe@vwvortex

its just programmed to react faster - similar to how the blue controller works on the MKI TT's, R32's etc.
