begins a year with many changes in technical regulations and in the sport. The following posts will explain the different changes, such as influence its behavior and that regulation is part of this change.
Rear Spoiler
This change is designed to improve overtaking opportunities. The adjustable front wing is gone along with the F-Duct very dangerous because the pilots had to operate it and hold a hand off the wheel and has given the green light to a mobile rear spoiler that reduces the "drag" or resistance of the progress thus increasing the top speed.
The system only has two options: ON and OFF and ON setting allows expand the distance between l and the upper primary level from 10-15mm to 50mm. The system will disarm when you release the button actuation or brake pedal.
Pilots may use the system at any time in the free and qualifying rounds while the race is limited to one section of the track specified by the FIA \u200b\u200band as long as the distance between cars is less than 1 second.
The system will only be activated after the first two rounds or after a safety car period and its availability will warn the driver by a witness at the wheel.

FIA Technical Regulation
3.10.2 - Other Than the bodywork defined in Article 3.10.9 , Any bodywork behind a point lying 50 mm forward of the rear wheel center line Which Is More Than 730mm above-the reference plane, and Sale less than 355mm from the car center line, lie in an area Must When viewed from the side of the car That Is Situated Between the rear wheel center line and a point 350mm behind it.
With the exception of minimal parts solely associated with adjustment of the section in accordance with Article 3.18 :
- when viewed from the side of the car, no longitudinal cross section may have more than two sections in this area, each of which must be closed.
- no part of these longitudinal cross sections in contact with the external air stream may have a local concave radius of curvature smaller than 100mm.
Once the rearmost and uppermost section is defined, 'gurney' type trim tabs may be fitted to the trailing edge. When measured in any longitudinal cross section no dimension of any such trim tab may exceed 20mm.
The chord of the rearmost and uppermost closed section Must Always Be Smaller Than the chord of the lowermost section at the Same Side station.
furthermore, The Distance Between Adjacent sections at longitudinal plane and Stock Must lie Between 10mm and 15mm at Their closest position, except, in Accordance with Article 3.18, when to lie Between this distance must-10mm and 50mm.
F-Duct
For 2011, the FIA \u200b\u200bhas expressly prohibited the use of motion of the driver to control any system that influence the car's aerodynamic characteristics. This means no more duct F (Mc laren great invention), where the pilot covered a hole in the cockpit to alter the flow of air into the rear wing. This allowed to enter the wing in loss, reduce drag and increase top speed.
FIA Technical Regulation
From 3.15 - Aerodynamic Influence - With the exception of the parts for the Adjustment NECESSARY Described in Article 3.18, and Stock car system, device or procedure Which uses, or is Suspected of using , driver Movement as a Means of Altering the Characteristics of the car aerodynamic is prohibited. Distribution
pesos
Coinciding with the arrival of a new tire supplier for the FIA \u200b\u200bimposed this year a mandatory weight distribution for this season. The weights distribuicón wheelbase is between 45.5% to 46.7% for the front axle and rear axle will be between 53.3% and 54.5%, which will affect the tuning of the car's dynamic behavior.
This relationship means that cars must weigh at least 342 kg on the rear axle and 291 kg in the front.
FIA Technical Regulation
4.2 - For 2011 only, the Applied weight on the front and rear wheels Must Not Be Less Than 291kg and 342kg respectivamente at all times DURING the qualifying practice session. If, When required for checking, a car is Not Already Fitted with dry-weather tires, It Will Be weighed on a set of dry-weather tires selected by the FIA \u200b\u200bTechnical Delegate. Diffuser
Roass Great invention Brawn in 2009 that allowed him to win the championship in 2009 and then all the teams were copied and improved throughout the season. The famous broadcaster BRAWN GP team has been the subject of much comment and controversy until they have sudo declared legal by the FIA. The main objective of this piece was to increase the speed of airflow under the car thereby achieving a decrease in pressure and increased downforce
From this year, this solution is restricted by law and can not see the holes in the bottom as seen in this image of last season's Ferrari. For this year, allowing broadcasters are simple and can be blown (escapes in the lower invented by Newey)
Here is a photo of the great invention of Brawn filed exactly two years ago and allowed him to fully master this major Brawn Award
FIA Technical Regulation
3.12.9 - In an area lying 450mm or less from the car center line, and from 450mm forward of the rear face of the cockpit entry template to 350mm rearward of the rear wheel center line, and Stock and Stock intersection of bodywork from beneath the car visible with a lateral or longitudinal vertical plane Should form one continuous line which is visible from beneath the car. When assessing the compliance of bodywork surfaces in this area the aperture referred to in Article 3.12.7 need not be considered.
3.12.10 In an area lying 650mm or less from the car centre line, and from 450mm forward of the rear face of the cockpit entry template to 350mm forward of the rear wheel centre line, any intersection of any bodywork visible from beneath the car with a lateral or longitudinal vertical plane should form one continuous line which is visible from beneath the car.
3.12.11 Compliance with Article 3.12 must be demonstrated with the panels referred to in Articles 15.4.7 and 15.4.8 and all unsprung parts of the car removed.
