no double clutch on the new F10 generation BMW M5?
"Has the time of the BMW Dual Clutch Transmission come and gone? Sources are indicating that the recently introduced DCT may be such a niche product that its time may be short lived. Porsche is feeling the same way with the famed PDK. The dual-clutch setup is fantastic in its implementation but remains an extremely niche product. According to Automotive News, transmission specialist ZF Friedrichshafen AG does not see a mass market for the dual-clutch technology that it sells to Porsche. Part of the issue is the cost to performance proposition of building a DCT that can handle lots of torque. With today’s performance cars increasing torque exponentially it leaves little market for the DCT.
With the introduction of the X5 and X6 ///M versions using a technically updated automatic transmission and cylinder deactivation to produce shifts as fast as a DCT the writing was on the wall for a possible end to the BMW DCT. What this means now is that in the short term we will more than likely not see future products offered with a DCT, with a shift to 8 speed automatics across the line by 2013. We have been told not to assume anything in regards to current offerings but that the ///M3 and DCT are a perfect match.
All you F10 ///M5 anticipators take note- this seals the deal that a DCT will NOT be in that vehicle!"

ashok,, i wished that u had the chance to try another vehicle SMG fitted,, im sure urs was one of a 1000 that had early model bugs,, which applies to many other vehicle

Ashok, pool Ashok...gun shy, can't blame him....4 transmissions? is that correct 4or 5?? just too many, period. Although I can NOT emagine the M5 with a stick,....did the Queen Mary have a stick???

why don't they just improve the technology to handle more torque? Not psyched on having a Lexus transmssion in an ///M.
With the continued improvements made in the automatic tranny, I see no role for the DCT/PDK double clutched trannies. The slush boxes will shift just as fast and offer unsurpassed smoothness.
Also, the DCT weighs a TON!! To beef it up more would mean MORE weight, which runs counter-intuitive to its purpose of development.
Personally, I prefer the SMG/single-clutched trannies. It offers the lightning shifts not humanly possible, and the connection to the road like a stick. I never understood the complaints people have with the 'jerkiness' of the SMG; it is a manual transmission afterall. If someone wanted smooth, get an automatic. I always felt that the double-clutched trannies were conceptually a good idea for speed of shifts, but reliability in handling the excess power will always be an issue, not to mention the weight of the component.
