Finally had the chance to scan the manual, as promised.. NOT THE BEST scan..

Is the DCT really that much better then the 335 step? I would imagine with more gears they can increase the final drive for shorter gears and thus more performance.

How would everyone rate in comparison to the step?

PS, thanks for the scan!

far superior to step. the shifts are crazy fast, blows the auto out of the water.

Thanks very much...

I always wanted to know how that SPORT button worked.

not 100% sure I get it though...

So when you are in S mode and then press the SPORT button, is that SPORT+ ?
or
when you are in D mode and then press the SPORT button, is that the same as moving the Shift selector to S or is it SPORT+ or somewhere between?

can any0ne clarify?

so it says the car starts in 1st gear by default? as opposed to 2nd gear with the regular steptronic. Interesting

DCT transmissions are more like manual transmissions in that they have clutches. Starting in 2nd gear would take a lot longer to full engage the clutch without stalling, and hence would increase clutch wear and reduce the life of the transmission. Also, since it has a clutch, torque is reduced when the clutch is slipping.

Regular automatics don't really have that issue since there are no clutches like manual/DCT. It's just the torque converter slipping, and that's not something that wears down like a clutch. The torque converter also acts as a torque multiplier when slipping, so it increases the torque output to the wheels when starting from a stop.

Can anyone shed some light on the workings of that SPORT button?

Thanks.

From the looks of the Manual:

If you move it into Sport like on the Steptronic, it will hold gears longer and you can shift up and down manually.

Pressing the Sport Button activates Driving Dynamics Control which makes the Transmission shift faster and the car reacts faster to the gas pedal

... I though it also has an impact on the active steering... but nothing is mentioned about that.
