SMG III?
E90Fleet? Wondering if the new M, if offerred with a non-manual version, will it have the current SMG that's available in the current 5/6 series? I have been curious ever since the older SMG has been discontinued for the E46 Coupe (and discontinued during the advent of the E90). Be it ZSG or what not, I hope BMW is going to release some sort of twin-clutch-based, clutch-foot-free system for the E90 335 or the M3.

the M cars have a different SMG than in the 5/6/Z4/E46
with the latest M cars coming in SMG only............ the 3 may be SMG only too (at first, but they'll probably cave and give all 3 options eventually) |

I have read that the M3 will have the M5 7 speed SMG and manual offerred concurrently at launch.
BMW is working on a dual clutch new-gen SMG, but it currently is not able to handle the torque of the M line of cars. |

BMW latest gearbox in development is a dual clutch basically like audis DSG. So look for that in a slightly later model. Until then expect SMGIII as an option and a base manual. Thats my guess anyway

Upon further thought I've heard it mentioned before that BMW M doesn't find this transmission suited to the character of the brand. M is suppose to be hard edged thrills, a transmission that doesn't give the driver the "feel" of the gearshift changes wouldn't be too incredibly on brand, but who knows, it could happen if M finds a way to tune it to suit the character of its cars. |

Some people just can't handle not being right, that's real immaturity, but I'm not here for petty arguments such as this. It's a fact that Porsche was the first to use this technology, NOT VW/Audi.

"Direct-Shift Gearbox
From Wikipedia, the free encyclopedia The Direct-Shift Gearbox (Direktschaltgetriebe) is a semi-automatic transmission invented by BorgWarner and initially licenced to Volkswagen (which also owns the Audi, Seat, Bentley and Skoda brands). By using two clutches, fast shifts can be achieved, and the inefficient torque converter of a regular automatic transmission is eliminated. Essentially, the engine drives two clutch packs simultaneously. The outer clutch pack drives gears 1, 3, and 5 (and reverse). The inner clutch pack drives gears 2, 4, and 6. Instead of a standard large clutch plate, each clutch pack is a collection of four smaller stacked clutch plates, due to space constraints. Because the alternate clutch pack's gearing can be pre-selected, upshifts occur in an impressive 8ms, though downshifts still take 600 to 900ms. This type of transmission is finding increasing popularity in Europe, and apparently also in America although some say CVT (Continuously Variable Transmission) is more popular in the US. BorgWarner who call their technology "DualTronic" have just (Aug 2005) signed further agreements with two other (unnamed) European Automotive manufacturers to incorporate their gearbox. VW group vehicles available in Europe with the DSG gearbox include: Audi TT and A3 VW Passat, Golf/Jetta and Touran Seat Altea, Toledo and Leon Skoda Octavia and Fabia. " I'm not saying its right or wrong as its wikipedia but hey, just thought I'd mention it! |

I can almost guarantee that the car will come with a 6-speed manual AND a new SMG IV system. "///M" stands for Motorsport, but it also stands for Marketing. They will want to produce a car thats all new, and engine thats all new and a transmission thats all new.

From the Getrag website I found the following - The 6MT from the E39 M5 and the E46 M3 are Getrag Type 226 transmissions http://www.getrag.com/176 and the SMG II is a Type 226 AMT. SMG III = Type 247 AMT http://www.getrag.com/183/183
I wonder if there is a Type 247 (non-AMT/SMG) 7 speed traditional manual... wouldn't that be weird? Something tells me no because the shift gate would be huge Anyway, everything I've read has stated the new M3 will have a 6MT standard and SMG III as an option. The M3 is a bit more of a drivers car than the M5 or M6 so I think there would be blood in the streets if 6MT wasn't available. As for a BMW dual clutch gearbox, (SMG IV?) My guess is it'll be an option when they "facelift" all three M cars. |

funny thread......
it was Porsche that designed the PDK tranny, for Touring car racing in the early 80's. How it got bounced around to Borg and Getrag, who knows. But, the Pcars WE'RE the first cars to use a Twin Clutch system. Argue all you want, but the PDK's have been around since the early 80's. My last 3 cars, before this BMW were Audi's. I know all about the heritage/lineage of the DSG. But, I'm a Bimmer man now...... can't wait to take Euro delivery of my new M3 sedan !! SMG7 or 6mt......... kj |
