Last week and without any ceremony the FIA quietly slipped a new link onto the 'invitations to tender' section of its website. The confirmation of plans for a standard Formula 1 gearbox for 2021 and beyond was hugely significant, since it's the first clear signal of what direction the rules are taking.
There has been a lot of talk since Liberty Media took over a little over two years ago, and the occasional statement that summarises the overall goals.
But until now, aside from the plans for 18-inch wheels, we've seen virtually nothing in the form of concrete proposals - in public at least. That's despite the huge effort being made by the technical teams of the F1 organisation (under Ross Brawn) and the FIA (via Nikolas Tombazis) to move things along.
