The complete 2011 SR and TR are now available at
FIA.com.
They've kept the silly 25-pt, 10-place scoring scheme. And the ban on refueling.
There's a new "Alonso" rule: no passing in the pit lane.
A new anti-F-duct rule: "[A]ny car system, device or procedure which uses, or is suspected of using, driver movement as a means of altering the aerodynamic characteristics of the car is prohibited."
And there's two new "Newey" rules. The first prohibits "any component or design which may have, or is suspected of having, any non-linear characteristics," which clearly is aimed at the flexy front wing. The second prohibits all the flexy skid block technology, which made the droopy nose possible.
The stewards have HUGE leeway in punishments they can mete out to drivers, ranging from stop-and-gos or arbitrary time penalties to DQing and excluding them from the next race.
Rather than eliminating the misnamed "safety car," the FIA have created yet more rules concerning driver's behaviour when it is deployed.
The stewards can waive the 107% qualifying rule, which they presumably would do in a case like Alonso's Monaco crash. However, their decision is beyond appeal.
An overtaking car may not be crowded beyond the edge of the track (read: no blocking).
A great number of tweaks to the construction of the survival cell.
Two tethers per wheel.
KERS specs unchanged.
Weight distribution fixed at a minimum of 291kg front and 342kg rear.
Regarding the adjustable rear wing:
TR 3.18.2: The adjustable bodywork may be activated by the driver at any time prior to the start of the race and, for the sole purpose of improving overtaking opportunities during the race, after the driver has completed a minimum of two laps after the race start or following a safety car period.
The driver may only activate the adjustable bodywork in the race when he has been notified via the control electronics (see Article 8.2) that it is enabled. It will only be enabled if the driver is less than one second behind another at any of the pre-determined positions around each circuit. The system will be disabled by the control electronics the first time the driver uses the brakes after he has activated the system.
The FIA may, after consulting all competitors, adjust the above time proximity in order to ensure the stated purpose of the adjustable bodywork is met.
Not sure how effective this new wing will be but it does bode well that they have left themselves wiggle room with the one second.
