While hot and cold blown diffusers and their ramifications were the talk of Silverstone - with the FIA issuing a clarification on the matter on Thursday - a different kind of power play was enacted in Bernie Ecclestone's sombre motorhome at the sharp end of the paddock, with no less than five team principals meeting with him to discuss engine matters present and future.
Almost simultaneously an FIA-called meeting was concentrating minds elsewhere, with the topic of discussion being cost saving and control under the 2014 V6 engine regulations. Therefore at roughly the same time during a rather fraught weekend, three engine-related issues were being discussed; all of them only peripherally related to each other.

Tellingly, the commercial rights holder, which is responsible for paddock layouts at each race, had decided to situate the FIA motorhome at the opposite end of the paddock - amongst the Pirelli tyre trucks and Virgin and Hispania motorhomes.
The first-named meeting was attended by Formula One Teams' Association chairman and McLaren team principal Martin Whitmarsh, his FOTA deputy and Renault F1 team boss Eric Boullier, Christian Horner, team principal of reigning double champion Red Bull, Ferrari's Stefano Domenicali and Ross Brawn of Mercedes.
