Aside from the "official" merger, that logo is one of the most boring and tasteless things I've seen in a while.
I know others may not share my same appreciation for graphic design, but here's some further insight:

Or, in summary from the article, as it explains best:
"And, unfortunately, it’s not just boring. It’s boring and poorly done. I can get behind the idea of minimal logos and my hard drive knows how many wordmarks I have myself designed and proposed based on letterforms that fit neatly in squares but this is just clumsy. The “F” is almost a square but isn’t (it’s like 95% there), the “C” looks weird with the terminals cut horizontally, and, the one that I feel ruins the composition, the “A”, just shoots over the other two letters creating an unpleasant incline. Three letters shouldn’t be that hard to get right. For a company devoted to the design of some of the most well-known, mainstream cars in the market this logo shows little disposition to precision or creativity.
