Formula 1 in early 2017 suddenly looks very different - off the track as well as on it. While the faster, wider cars pound around the race circuits of the world at incredible speeds not seen for years, the political landscape has also changed dramatically.
Bernie Ecclestone held sway at the top for nearly 40 years, and anyone who wanted to push in a different direction had to be sure they knew what they were doing, and that they had the leverage to see it through. But now Ecclestone has gone, shunted off to a chairman emeritus role, and effectively been told not to speak unless spoken to.
The past has gone. To be replaced by...what, exactly?
