No British GP thread? Someone sleeping at the switch?

So, Renault and Mercedes are given an exception on banned diffusors?

To a certain degree, it looks like.

The Autosport article gives a pretty detailed rundown.

What banned diffusers?

Quote from boothy :

Pretty sure there was no speed limit back then, and just look at the amount of people in the pitlane (when there's no stops ongoing) compared to nowadays.

There was no speed limit indeed - it got introduced after that very week-end...

Quote from BlueFlame :

What banned diffusers?

Blown ones?

Quote from TexasLTU :

Blown ones?

You mean, overrun engine map?

Yes, the engine map that blows the exhaust on the diffuser.

Quote from DeadWolfBones :

Yes, the engine map that blows the exhaust on* the diffuser.

*under

That's what a blown diffuser does. Blows under.

Yes and no.

They've been given some concessions on reliability grounds.

Mercedes is allowed to fire half of its cylinders (ie. 4 of its 8 cylinders) while drivers brake. This is effectively hot-blowing but at 50% of the potential maximum. Hot-blowing has been banned for all others.

Renault is allowed to open its throttle up to 50% while drivers brake. However, Renault engines cannot hot-blow. So Renault teams - including RBR - basically get to do what they've always done: cold blowing under braking.

Red Bull was using 45% beforehand, and the maximum is 50%? That harms only Lotus Renault itself, who were using 90% ot these cold blows. FIA failed... again.

redbull will still loose out as they can't hot blow which is where all the real grip comes form.

I suggest we move this conversation to the British GP thread which is where we will see the impact, or the general 2011 season thread for the overall picture.
