The FIA has changed the direction of car development for 2011 by deciding that blown diffusers are to be deemed "movable aerodynamic devices". They do this by once again defining the obvious:To push this regulation change through, the FIA has deemed that throttle use will be allowed only for the purpose of increasing torque, not for 'aerodynamic performance'.Some people give this feature credit for Red Bull's dominance over the rest of the field, but it remains to be seen if this will actually change anything at the front.
The FIA has thus far been silent as to the reason behind the change in rules interpretation.
Update, perhaps 20 minutes later: Or not:
Formula 1 teams have been given a reprieve to continue using blown diffusers freely from this weekend's Spanish Grand Prix, AUTOSPORT can reveal, after the FIA had a rethink about going ahead with a major change to the regulations.Want to bet one of of those "unforeseen" consequences was the Red Bull being relegated to running with the Lotus cars?
[...]
A high level source indicated that the decision had been taken because a number of 'unforeseen and unintended consequences' of the ban had been brought to the FIA's attention.
