I'm sorry, but you are wrong for at least one of the manufacturers you listed. I only found one Mercedes model where they reported a slower 0-100km/h time for the version with the automatic transmission.
I'm pretty sure the numbers for the other manufacturers are similar. Automatic transmissions have simply surpassed manuals. Yay, technology!

The A6 2.0 TDI accelerates faster with an automatic transmission (8.2s vs. 8.4s), and is more fuel efficient (4.4l/km vs 4.5l/km)

C&D review of the VW Golf R: "The manual loses to the automatic Golf R against the stopwatch. The 0.7-second deficit from zero to 60 mph, which takes 5.2 seconds, is almost fully attributable to the two shifts required to reach 60" http://www.caranddriver.com/volkswagen/golf-r#eztoc8578403_0...
I couldn't find a manual Mercedes on their website, Skoda isn't for sale here, and I couldn't find 0-60 numbers on VW's website so I quoted an automotive review instead.
The general consensus I've seen is that automatic transmission cars are faster than manual transmission cars 0-60.
Come on.

Beschleunigung 0-100 km/h in s: 7,9 [7,8]
Numbers in brackets are with automatic transmission, and it outperforms the manual transmission in both fuel efficiency and acceleration.
Not gonna do Skoda and Volkswagen, feel free to prove me wrong though!
