There is a clutch, it is controlled by a computer electronically...or so BMW says, but it's been discussed here before that really BMW cloned Webster and he is doing the shifting for you inside the transmission.

but then, u don't have to step on it when u shift right? like a clutcch-less manual? and what are the 2 extra buttons for?

right, there is no clutch pedal.

The left "button" is for down shifting and the right one is for upshifting. When you pull eithe level back the car's computer disengages the clutch, shifts the tranny then either upshifts or downshifts automatically.

Theoretically, it's faster, in practice, it's just more consistent.

While I DO think that I'd have a lot more fun in a 6spd M3, I suspect I'd be faster with SMG. The absolute best drivers will be faster with a proper manual due to the increased control. Until they get tired.

STILL CONFUSED

sorry but, if the buttons were to downshift and upshift, what is the stick for?! or u gonna use the button and the shift at the same time?! so it's simply just clutch it with ur fingers?! :dunno:

I believe you can use either the buttons or the stick to shift up or down (not both at the same time) and that you use the stick to get into other modes (reverse, ect,). I'm not certain about the 2nd half, I'm pretty sure about the 1st half.

Well at the drag I was able to beat SMG. SMG fastest time was 13.9. I got 3 times goin 13.8 and had ****ty reaction times. My best reaction time was .637

a) Who gives a **** about the drag strip? It's completely irrelevant to what the M3 is designed to do. SMG is relevant at the TRACK, where fast and consistent DOWNSHIFTS are important. Anyone who is semi-competent with a clutch can upshift quickly and smoothly. The real test is in the downshift. SMG is about CONSISTENCY, not absoulte speed. It's damned fast EVERY time, rather than really damned fast some of the time.

b) First gear is the one area that SMG is weak in. After all, launch assist only operates at 1800 RPMs.

smg is only slightly slower from 0-60 is because it's really hard to launch that sucka, but if you did a rolling start, and with SMG on the most aggresive setting, i am sure it can take the 6sp easily

edit: MON from e46dtm said that smg pulls harder so he got rid of his 6sp for a smg :dunno:

Well ok I noticed that the downshifting isn't as fast as mine. I saw this jap vid and it had 360 Modena 6 and F1, Evo 7 , and M3 6 and SMG. 6 speed beat it:flipoff:

Edit: ohh yea why would I want 2 clicks rather than shift really fast into the gear I want to.

On the track I think 6-speed would have the advantage (in capable hands) because you can rev match, slip the clutch, etc ... it's all about control

I saw that video, too. All the sequential drivers were incompetent.

Besides, I never said that SMG is faster per se. I said that it's more CONSISTENT. Think about how well you shift after hours sitting in the driver's seat. Now, imagine how well you'd shift after hours ON THE TRACK.

Finally, you will notice that I said the 6 speed is more FUN.

SMGII heel-toes perfectly every time when driven at high revs.
Like I said, you might be faster for a couple laps with a 6 speed... But you'll get slower as time goes by. SMG, OTOH, is just as fast throughout the whole process. Consistency is more important than peak speed if you're talking about performance.

The SMGII has both the levers on the wheel and the knob in the console, but they both pretty much do the same thing...you just use whichever you are more comfortable with when shifting. As far as the performance goes, no loss, but you still want to treat it like a manual nonetheless; what i mean is come off the gas when you shift...it shifts a lot smoother and doesn't upset the car. The automatic mode is not that great, it is a manual after all, and is not smooth around town like a traditional auto. It is an amazing tranny though!
