FIA takes U-turn on off throttle diffuser ban after F1 teams protest
Formula 1 governing body FIA has taken a U-Turn on the engine mapping ban which they have enforced prior to the British GP. FIA has said that the teams are now allowed to use the off-throttle diffuser in this season.
FIA imposed the ban on the use of off throttle blown diffuser after the European GP but soon withdraw it temporarily before the Silverstone qualifying session. But on Thursday FIA officially declared that they are taking the off and the teams are free to use blown diffuser. FIA wanted to impose the ban because the teams were using the exhaust gases for the aerodynamic benefit even when the drivers are off the throttle.
Prior to the British grand prix the leading Formula 1 teams started lobbing against the new rule and they raised questions about the fairness and the enforceability of the new restrictions. Red Bull team chief Christian Horner and designer Adrian Newey strongly raised their voice against the new rules and said that it will raise reliability questions as the Red Bull car is designed around the blown diffuser.
FIA after the protest gave 50% concession to Red Bull and Renault because of the reliability reasons. They were allowed to use 50% of their blown diffuser under braking. FIA also gave concession to the Mercedes GP team but FIA soon withdraw it in the half way stage after the Friday practice session.
The FIA Technical Working Group discussed the issue with the teams to carve out a solution which will be acceptable to all of them. After that FIA said that they are willing to keep diffuser till the end of this season on which all the team agreed.
Ferrari and Sauber however, withdraw their support but FIA issued the statement which states that the teams are agreed to use the off-throttle blown diffuser and FIA is reverting its decision and the team are now free to use off-throttle blown diffuser however, the ban on engine mapping will be in effect.
The FIA document reads like this:
FIA also said that they are hopeful that the teams will now not protest against each other on the same issue in the remaining 10 races of the season because the off throttle rules are tailored according to their requirement.
However, FIA has lifted the ban on the off-throttle blown diffuser for the 2011 season but FIA has said that they are confident that the ban will come into effect from 2012 and that time they will not change the rules like this time.
