OK Dozhdbog, I finally had some time to go through Car and Driver's website and look up all their 335i tests, and they did plenty!
So, since we have test data for both transmissions from the same tester, we have a fairly objective alternative to BMW's test data.
So we finally have a pretty reliable answer to which is faster, the 335i with 6 Speed Manual or 335i with 6 Speed Steptronic Auto...
Drumroll...
NEITHER ONE IS CLEARLY FASTER THAN THE OTHER!
Take a look at the following test data. Note that there is only one test where the car definitely had the Steptronic. In the other test (noted) both transmissions are listed in the data panel and the article text does not clear this up.
Some of the tests suggest that the 6MT might be slightly faster, since there are two tests with a 0-60 result of 4.8 seconds, both are 6MT. But I think 0.1 sec is probably the margin of error, and if you scan the data you can see 0.1 sec variations in the other acceleration tests, going both ways. To me 0.1 seconds is just not a significant difference.
Note that the 335is, with +20 HP, +70 lb-ft of torque on overboost, and DCT, only beats the fastest 335i 0-60 time by 0.2 seconds.
But if there is one point that is going to have to be conclusively settled, is that the
6MT 335i is not slower than the 6AT 335i. There is no way you can twist the data to support a claim that the 6MT is slower.
Here is the data:
