Does somebody know why Mercedes tested two different aero specs in Barcelona pre- season testing? Were these two specs with completely different downforce levels?
There were differing reports in the media about why they did what they did. Mercedes themselves said, they were not ready for first test as the team needed more time to finish the car and hence, had decided to bring a car that was probably an earlier iteration (a few months old).
There are other paddock reports that suggested, Mercedes did not want to bring their actual car for first test as the first test was being covered live on TV and they wanted to hold back until second test, which was not being covered on TV.
This report appeared in Italian Motorsport site and was something that I had posted soon after the first test. So, whatever was the source of the author, seemed quite reliable as no one at that point knew what Mercedes was up to.

Link -> How many Mercedes experiments: the W10 simulates the rear steering wheels
The silver arrow in the first test session in Barcelona tried the basic set-up: the front was chosen for the push rod strut, while behind it worked on four steering wheels and the height from the ground. The real Mercedes will appear next week.
May be they were trying to protect their Barcelona S3 performance advantage from any kind of video analysis from live TV footage? I guess we would never know.
