Shall I do the thread again  Well, sure wasn't a bad race. I won't say what happened as the bbc haven't shown it yet! Your comments and opinions here once you have seen it  |

Button has gotten over his front tire lockup issues...I believe this was a technical thing based on brake bias, mechanical suspension loading via springs and shocks...and of course front wing adjustment. Unfortunately it took his team a while to sort this. Good to see him competitive again.
Vettel, he ran off the track to make a pass. This is a definate no-no, so he lost several places after the dust settled. He was not run off the road, just pushing the issue too much. I agree with the stewards on this one.
Fernando, I tip my hat to you. Fantastic finish...tires going off but the bull finished in front.
RBR, technical issues regarding engine mapping, blown diffussers, and the rules...there was a bunch of speculation on this one. I don't have an opinion unless someone has more technical info.

To fix the loophole, the FIA could write a rule that said: "The accelerator pedal travel will be defined as 0% (minimum) to 100% (maximum) and at any position between these two end stops the percentage torque output of the engine base torque map for the measured engine speed must match the accelerator pedal percentage +/- 1%...
"This would mean the relationship between throttle pedal position and the torque delivery must be linear.
"And the rule could finish by saying: "… and the percentage of throttle body opening must match the accelerator pedal percentage +/- 10%.
"That would mean any change in torque characteristics could not be done by just retarding the ignition - a common method of employing engine braking - while leaving the throttle open to pump air through the engine and exhausts, which is a way of using the exhausts for aerodynamic effect.
"Allowing a margin of +/- 10% provides some leeway for the characteristics of different engines, as all have different operating requirements."

Motor racing's governing body, the FIA, is expected to issue a further directive on engine mapping before the forthcoming Hungarian GP this weekend. It is understood that Red Bull Racing will not be able to run the same map that FIA technical delegate Jo Bauer considered to be outside the regulations in Germany.
It was perhaps no surprise that the Hockenheim stewards did not uphold Bauer's opinion, as much as anything because the matter is complex ans they were in no real position to make a ruling on the matter in the few hours between Bauer's report and the start of the German GP.
Rival teams were keen that the matter went straight onto the agenda of yesterday's Technical Working Group meeting.
McLaren's Martin Whitmarsh said: "If you are allowed to do that, everyone will be spending a lot of money to run that kind of map and as quickly as you can. Clearly, the FIA is frustrated by it, so better to stop doing it."
His opposite number at Ferrari, Stefano Domenicali, added: "We are relying on the regulator, the FIA, to make sure that it is a fair fight."
As a result of the TWG meeting it is believed that the FIA will specify the amount of torque variation permitted across the rev range in a document due to be issued before the start of practiceon Friday in Budapest.

Formula 1 bosses have introduced a rule change to outlaw controversial engine settings on the Red Bull.
The issue, which arose at the German Grand Prix, surrounds settings that ran counter to the intention of the rules, improving cornering performance.
Red Bull were cleared by race stewards because they said the settings did not break the rules as they were written.
The new ruling limits how much teams can change specific settings and applies from the Hungarian Grand Prix.
The row revolves around an immensely complicated issue to do with the computer settings - so-called maps - that control the amount of torque delivered by the engine in various conditions.
What is torque?
Torque is defined as "the twisting or rotary force in a piece of mechanism (as a measurable quantity)".
The amount of torque in relation to the engine speed can have an affect on the car's traction.
Torque definition according to the Oxford English Dictionary
The ruling specifies the limits within which maps can be changed from race to race, as well as other settings.
The FIA's concern in Germany was that Red Bull were using reduced torque settings for a given engine speed. It felt these could act as a form of traction control, limiting wheelspin out of corners.
Rival teams believe Red Bull's actions also allowed them to make more effective use of the exhaust gases for aerodynamic effect.
Governing body the FIA found that Red Bull's engine was delivering less torque at full throttle in the mid-range of the engine's rev band in Germany than it had at the preceding British Grand Prix.
They said this was a breach of article 5.5.3 of the technical regulations, which states that the "maximum accelerator travel position must correspond to an engine torque demand equal to or greater than the maximum engine torque at the measured engine speed".

Blacktulip, I understand your great description of the engine mapping controversy, but have a question. This mapping is also tied in to the blown diffuser debate. I thought that blown diffusers were banned, and that the exhaust gasses cannot exit into the diffuser anymore. Before the German GP, there was an army of red bull guys standing in front of the rear diffusser (no piccy's please!)
Are there 2 infractions here? Traction control (implied through complex mapping) and a blown diffusser being used?

Cristian Horner claims that Vettel was robbed when he was given a 20 second penalty for passing with 4 wheels off track. I think the penalty was appropriate, to move him back to fifth. He's also pissed that Hammy passed him...jeez! a faster car passed him and Vettel's arms are flailing and feelings are hurt. Get over it Christian, this is racing. Here is some good commentary on these two incidents: www.grandprix.com/columns/maurice-hamilton/going-too-far.html |
