Latest Formula 1 technical regulations emphasize to ban double DRS (Drag Reduction System). Initially Mercedes AMG was introduce this system and they are used this concept in early in this season, following Lotus F1 was tested this design in the mid-term of this season but not run with race.
Article 3.18 states that the moveable rear wing: “cannot be used to change the geometry of any duct, either directly or indirectly, other than the change to the distance between adjacent sections permitted by Article 3.10.2.”
Formula 1 introduced this season a vital concept as ugly designs in front nose of the car (stepped nose). McLaren is the only team, not adapted this concept and they are still running with traditional design but slightly bended their front nose.
After the conversation between teams to come up with a solution to the stepped noses designs that would not involve a big redecorate for 2013 F1, FIA has announced that the new rules that will permit a special ‘modesty panel’ to be fitted.
In 2013 F1 teams will have the choice of fitting an individual panel to their cars and it will help hide stepped noses.
Article 3.7.9 of the Technical Regulations states: “With the exception of an optional, single piece, non-structural fairing of prescribed laminate (whose precise lay-up may be found in the Appendix to the regulations) which may not be more than 625mm above the reference plane at any point, no bodywork situated more than 1950mm forward of rear face of the cockpit entry template may be more than 550mm above the reference plane.”
