[QUOTE="B33mEr, post: 330407, member: 13609"] DCT if i'm not mistaken is a Dual Clutch Transmission system similar to VW DSG. Fyi ... SMG (SSG), SMG1,SMG2 and SMG3 is an AMT system whereby it's a normal gearbox only w/o a clutch pedal. DCT is a new offering from BMW where it was offered 1st on the M3 convertible shortly after it was also available on the E90 M3 sedan ... when one select an odd gear number e.g 1,3,5 the DCT g/box already have the next even numbered gear e.g. 2, 4, 6 engaged ready and waiting for the driver to engage the next shift hence the gearchange is very fast and smooth, it's like having 2 g/box in 1 hence the term dual clutch transmission (DCT), unlike the SMG systems which has only 1 clutch for all the gears. Having said that DCT system adds the overall weight of the car and it's much more complicated than SMG system [/QUOTE]
