BMW debuting dual-clutch gearbox in M3 sedan
by Damon Lavrinc on Sep 18th 2007 at 2:03PM 
The expansion of BMW's M3 lineup is expected to take place sooner than we anticipated, and a new version of the Bavarian bomber will finally put the oft-maligned sequential gearbox to rest. According to Auto Telegraaf, BMW will be debuting the M3 sedan at a major Stateside auto show, likely L.A. or Detroit, and along with an extra set of doors, it'll be sporting the automaker's new dual-clutch gearbox. Rumored to be dubbed "M DCT," the new 'box will get seven forward gears that can be controlled by either a new shift lever, much like the one found in the new X5, or steering-wheel mounted paddles shifters. BMW also plans to offer a traditional six-speed manual for those who prefer to row their own gears.The regularly spied convertible version of the M3 is also on its way, which is proving to be an engineering challenge for the M-division due to the extra tonnage the retractable hardtop tacks onto the curb weight. We've heard that a track-bred CSL is also under development, and that its debut is likely to take place some time in 2009.

Knowing BMW the DSG-like tranny adds another 300 lbs to the car's weight. It'll be the first M3 to break the magical 4000 lbs barrier. What's next for the M3? The 4500 lbs M3 convertible.

Bimmer's definitely got a weight problem.
Besides, I'd much rather row the gears myself...like anyone's gonna use the manual function on an automated manual anyway.

We've got an a3 with DSG and any time I borrow my fiancee's car, I use the manual functions. Constantly. It's too much fun not to use them.

Only 1 way to get your hyperformance kicks w/o the Germanic bloat which affects the M3 and its bretheren:
Buy a Lotus!

That's a great answer...to just about EVERY bloated "sports" car!

"It's a manuel"
"No it's not, it's an automatic"
"No it isn't"
"Yes, it is!"
"No it isn't!"

Blech. The latest M3 already does too much for the driver, way to isolate it even more.
Forget about the absolute performance, some of us actually like to enjoy the experience. Well, at least Lotus doesn't appear to be interested in this crap.

I'd like a four-door M3 with a six-speed manual, thank you very much.
Barring that, I'll take the E46 M3. Despite what Car and Driver said, it just seems to me the E46 is more visceral than what the new M3 will be.

Su-weet. I couldn't be more excited about this news, and i'm currently driving a 6sp e90.
The DCT's are just sweet, faster switching than the manual and better fuel economy too. Only draw back will be some weight gain (compared with manual). I hope the DCT replaces all their slushes soon.

300 lb penalty ?? surely it cannot be that bad!
I hope they make this available on the lowly 335i...
Every car I have ever owned has been a manual tranny, but recently I got to drive a maserati with the F1 transmission. So nice!

Oh no... BMW taking a page from Lexus and offering a slushbox on a "sports car" rather than a true manual, somewhere in hell there is a flying pig at a corner that's freezing...and his name is Hansel...

Get your facts straight.
1. The cars are available with standard manuals
2. Direct Shift Gearboxes (DSG) ARE manuals. They are computer automated but they have clutches and gears are changed WITHOUT a torque converter. Automatic transmissions have torque converters.
I sincerely doubt you'd call an F1 driver an automatic driver even through they're changing gears without a 3rd pedal. Ferrari's SMG/DSG-like system easily outsells the traditional manual now.
While I may still prefer an old school manual, if I were tracking more often, I'd want the DSG/DCT as perfect shifts are intoxicating prior to hitting a corner. No heel-toe, just tap and make it happen in a flash.

icu812ru469, do you also think F1 and Rally cars have "slushboxes"? Do you have the slightest idea how these transmissions work? And what slushbox really means? Btw, those aren't really questions I need you to answer...

Does anyone know wether the new dual-clutch gearbox will for sure even have an "automatic" mode?

Eh, just stick with the 6MT. There will be an SMG version which offers automatic, not like the E36 automatic M3/sedan that bmw offered back in the day, which you can get if you are so inclined.
