Ross Brawn has scolded Mercedes’ critics as a protest threat continues to hang over the Australian grand prix.
Lotus is concerned the silver W03 features illegal aerodynamic solutions, and on Saturday raised the prospect of post-qualifying or post-race protests.

“It’s an option,” boss Eric Boullier is quoted by the Sun.

“All I can say is Red Bull and ourselves do not believe the Mercedes system is legal.”

Asked about the prospect of an official protest, Mercedes’ Brawn is quoted by Germany’s Auto Motor und Sport: “That would be very disappointing.

“If someone believes a car is illegal, then he should protest before the weekend, not afterwards.”

Brawn’s argument is that a pre-event protest gives the FIA a chance to respond and, if necessary, request a team make changes to its car before official results are filed.

He continued: “We have always informed the FIA about what we are doing.

“On Wednesday of this week they took a close look at the system in our garage and found it to be legal.

“As long as the FIA has this opinion, we will use the system,” said the Briton.

Brawn, in fact, smells diversionary tactics, amid earlier speculation about the legality of some exhaust solutions — notably Red Bull’s.

“The discussion about our system has diverted the focus from the exhaust issue,” he agreed.

Interestingly, McLaren has stayed out of the debate so far, stating simply on Saturday that it will not join a Lotus and Red Bull protest.

Team boss Martin Whitmarsh has now revealed his designers are working on something similar.

“We think we know what to do,” Auto Motor und Sport quotes him saying. “In general it is difficult with the limited space in a formula one car to integrate systems at a later date.

“But I don’t think we are going to have problems,” added Whitmarsh.

F1′s governing body is investigating how Felipe Massa escaped penalty despite getting a head-start in last Sunday’s Belgian grand prix.
 
As the cars lined up on the Spa-Francorchamps grid, BBC commentator Martin Brundle noticed that the Brazilian’s Ferrari was about “two metres” ahead of its starting box.
 
And a spectator’s amateur footage, posted on video sharing website Youtube, backs Brundle’s observation, even though the race director, stewards and rival teams and drivers apparently did not notice or report Massa’s head-start.
 
The Telegraph said the FIA has launched an investigation into how Massa escaped without a drive-through penalty.
 
The report said the transponder on the floor of Massa’s F10 did not send a signal to the tarmac sensor because he was too far out of position, while the marshals did not alert the race director manually.
 
“As no further information or complaints were received before the publication of the official result on Sunday night, the classification of the Belgian grand prix will now remain unchanged,” said an FIA spokeswoman.
 
“The FIA are investigating the causes of the apparent failures in communication with race control in order to ensure a repetition is not possible,” she added.
