The new M DCT transmission that the M3 will offer this summer. It�s a Dual Clutch transmission that promises to be all things to all people. Apparently BMW has so much faith in the technology that they will be replacing the automatic in the 3 Series altogether next year for a non-M version of this dual clutch transmission.
Based on their technical similarity, you could expect the transmission to potentially find it�s way to both the 1 Series and the X3 in the near future as well.
