What is the difference between the SMG transmission, the 6-speed manual, and the 6-speed automatic w/ steptronic? How does the SMG transmission work is it a manual or an automatic w/ paddle shift behind the steering wheel?

SMG is basically steptronic all the time, it changes gears much quicker however. Steptronic is an Automatic transmission that can be turned into, like the SMG, a clutchless manual....kinda makes those who have an automatic feel like they can drive a manual and look cool. SMG is this all the time, simply shift up and down, no clutch...

Is it harder to learn the SMG Transmission or just a regular 6-Speed Manual? Is there anywhere to download a BMW 545i PDF Manual. Is the 06' model going to be different or have morehorse power? I want one of these cars so bad.

harder driving a traditional manual... because there is clutch.

with smg you can either leave it up to the car to shift or just shift up down via pushing a stick left or right.

Under "the SMG ll authority" you have choices of shift modes, the sequential S mode or the automated A mode. What BMW calls (drive logic) permits the tailoring of SMG shift to your driving habits armed with 10 or 11 different programs. Also the engine will automatically double-declutch for you. As ///Mat and Torque did explain there is no conventional clutch or torque converter.

Actually, SMG does have a clutch, it is just computer controlled. It is a manual tranny with an computer controlled clutch, feels like a manual more then step because basically, it is...

yea, smg has a clutch like I said, controlled hydrolically

[sp0rky]

Actually, from what I hear from owners of SMG, it's a little MORE difficult to learn than traditional manual because its not as simple as just clicking up / down a gear, it takes some skill to match RPM and other stuff. I don't know how true it is, but I have heard it quite a few times from a few smg owners.

either way, smg is the fastest shifting of the 3 trannys you mentioned, if thats what your looking for go smg. If your looking for nutty driving, wasting tires, etc, stick with the traditional manual and for traffic, daily driving, etc ... automatic.

well, my dad's 03' m3 is SMG, and having drivin' that, and my brothers 5speeed 328is, I would say that being good at manual is much harder than smg. SMG takes nothing but a little getting used too, it shifts so amazingly fast, its truely an amazing technology, i really love SMG, I think everyone should go and just test drive one, your opinion (if negative) will change

""Sequential Manual Gearbox (SMG):
SMG is a clutch-less manual 5-speed transmission that is operated by two paddles behind the steering wheel or via the gearshift lever"".


I am a bit puzzled by the above statement/quoted from BMW website when compared to your post. can you elaborate please? used used

Hi. What BMW is trying to say is that there is no clutch that the driver has to interact with. There is, however, a cluth that is controlled automatically by the car's computer but you don't have to do anything with it.

The SMG is basically the 6-speed manual and the Automatic combined. People who want both, you should get the SMG.

Thanks.
Bye.

This is just fine and we have no problem with it. BMW says clutchless, slvr e39 says clutch! How can I engage the argument not the gears? LOL
