The FIA have made a number of changes to the Sporting and Technical Regulations for the 2009 Formula One season, and the results of some have already been seen in testing.

In the case of the Sporting Regulations, the primary aims are increased reliability and further cost reductions. In the case of the technical changes, there are three main objectives - reducing the role of aerodynamics in the cars’ performance; making overtaking easier; and keeping lap times in check...


Tyres

Image

After 10 seasons on grooved tyres, Formula One racing returns to slicks in 2009, as part of moves to increase the emphasis on mechanical rather than aerodynamic grip. With no grooves, grip will increase by around 20 percent, bringing a significant performance gain. However, that gain will be offset by the vastly reduced downforce levels of the revised aerodynamic regulations (see below). The overall effect should be reduced performance through high-speed corners. Drivers will still have the choice of two dry tyre compounds and will still have to use both compounds during a race.


KERS

Image

From 2009 teams have the option of employing a Kinetic Energy Recovery System (KERS) to boost their car’s performance. As its name implies, a KERS recovers the (normally wasted) kinetic energy generated by the car’s braking process. This energy is stored using a mechanical flywheel or an electrical battery and then made available to the driver, in set amounts per lap, via a ‘boost button’ on the steering wheel. Under the current regulations the power gain equates to around 80 horsepower, available for just under seven seconds per lap. This could be worth several tenths of a second in terms of lap time, but the weight and packaging of the system - and its impact on the car’s weight distribution - also have to be taken into account.


Engines

Image

In a move designed to boost reliability still further, drivers must now use the same engine for three, rather than two, consecutive events. There are also plans for measures to equalise engine performance between teams. How this will be achieved has not yet been finalised


Aerodynamics

Image

Along with slick tyres, this is the biggest area of change for 2009. Downforce will be dramatically reduced and the cars’ bodywork will appear much cleaner, thanks to new dimensional regulations that effectively outlaw extraneous items such as barge boards, winglets, turning vanes and chimneys.

As well as reducing overall aero performance, the revisions are also designed to increase overtaking by making the car less susceptible to turbulence when closely following another driver. The most obvious changes are to the front and rear wings.

The front wing becomes lower (75mm from 150mm) and wider (up from 1400 to 1800mm - the same width as the car) with driver-adjustable flaps. Drivers will be allowed to make two wing adjustments per lap, altering the wing angle over a six-degree range.

The rear wing becomes taller (up 150mm to bring it level with the top of the engine cover) and narrower (750mm from 1000mm).

Also at the back of the car, the diffuser has been moved rearwards, it's leading edge now level with (rather than ahead of) the rear-wheel axle line. In addition, the diffuser has been made longer and higher, all changes that will reduce its ability to generate downforce.


Testing

2008’s testing allowance of 30,000 kilometres is expected to be slashed by a third to 20,000 kilometers in a bid to further reduce development costs.

Very nice and i think the 3 race rule will be interesting for next year. I still have my doubts about KERS and the medal system though.

I read (TS) that FOTA has decided to go even further with their cost cuts. The engines have to last 4 races and the test limit will be 10000 kilometers. Thus there will be only two or three test sessions next season.

On the other hand I think that will mean that those who have advantage at the start of the season will enjoy it as it's hard to develop and test new parts much then. Test drivers won't be participating much either since the teams have to use their kilometers carefully.

4 races is quite a lot. There will be a massive difference between two cars with an engine in their first race and fourth race.
Jarno in Belgium said that an engine in its second race was about 2 tenths slower. Thats is not true for all races but its going to be like that if it has to last for 4 races. This will certainly give more priority to consistensity rather than being fast.

Yes and in other terms it will be a nice to see all driver getting penalties and opting for 1 stops and alot of things

Also the introduction to slick tyre means, that if it is damp, then you are going to have very very less grip. The current grooved tyre would last in damp condition but its not the case with slicks.

Whatever may happen but one thing should not happen Ferrari should not be like 2005 instead they should be strong as 2004 :D

Safety Car Rule Change

In 2009, when Safety Car is deployed, pit lane is now open which means teams would be able to enter into pits whenever they want so provided that they cruise with a speed determined by ECU after receiving a SAFETY CAR DEPLOYED message.

What is more, pit lane speed limit is increased to 100 km/h.

and still lapped cars can overtake the safety car to take their position?

Yep, that rules will be the same as last year. Lapped car may overtake the Safety Car.
