It is no coincidence that Ferrari has earmarked Silverstone as a key indicator for its approach to the remainder of 2011.
It is at Silverstone that the FIA's controversial clampdown on blown exhaust technology, to be confirmed after a technical meeting in London this week, is expected to take effect.
"The rule changes are going to spice things up," predicts Lewis Hamilton.
"It's probably a combination of things but it's no secret that they were the first to develop the blown exhaust that has now reached a very high level of evolution."
We need to get the maximum points possible in Valencia and then look at Silverstone
In the Spanish newspaper Diario Sport, Ferrari boss Stefano Domenicali confirmed that Silverstone is a decisive event for the Maranello based team.
"Now we need to get the maximum points possible in Valencia and then look at Silverstone, which is where we will see the real effect of the change in the rules," said the Italian.
The Italian magazine Autosprint said Red Bull is furious about the ban and is arguing behind the scenes that it may even be illegal.
RB7 designer Adrian Newey said in Canada: "I agree with rule changes in the middle of a championship for good reason, like safety, but this is not the case. It's absurd."
