F1 vehicle 2009 rule

Subject: F1 vehicle 2009 rule 4/3/2009, 8:20 pm

Slick tyres will return for the first time since they were banned for the 1998 season. Bridgestone will continue to be the sole supplier of tyres, and drivers will still have to use both compounds of tyre during a race.
These compounds are differentiated by a green marking around the sides
of the tyres, rather than a white marking in a groove as used in 2008.
The aerodynamic regulations
have been radically altered for the 2009 season. Front wings will be
lower and wider, while rear wings will be much higher and narrower.
This makes the 2009 cars strikingly different in appearance from those
of previous seasons, and several drivers have expressed concerns that
the larger front wings could trigger more accidents; especially at the
start of Grands Prix when the cars are racing close to each other. As
well as the changes in the dimensions of the wings, bodywork will be
much more regulated with many of the additional components seen in
previous seasons effectively outlawed (including barge boards,
winglets, turning vanes, chimneys, viking horns and dumbo ears), the
diffuser at the rear of the car has been moved back and upwards. Many
other minor chassis components have also been standardised. The aim of
the new aerodynamic regulations, as well as the reintroduction of slick
tyres, is to decrease reliance on aerodynamic downforce and increase
mechanical grip with the aim of making wheel-to-wheel racing easier.
For the first time, cars will be allowed to use driver adjustable bodywork,
in the form of adjustable flaps in the front wing. The flaps can be
adjusted by up to six degrees, limited to only two adjustments per lap.
Along with changes to bodywork and tyre size, the 2006 document includes details of a "Kinetic Energy Recovery System". This is a regenerative braking device designed to recover some of the vehicle's kinetic energy, which is normally dissipated as heat during braking. The recovered energy can be stored electrically, in a battery or supercapacitor, or mechanically, in a flywheel,
for use as a source of additional accelerative power at the driver's
discretion by way of a "boost button" on the steering wheel. The
regulations limit the additional power to around 82 hp for six seconds
a lap. The regulations do not make this compulsory, and due to concerns
about both limited performance gains and safety implications many teams
are believed to be unlikely to use the new KERS systems for at least
the start of the 2009 season.
While it was reported in 2008 that the FIA were planning on
introducing a budget cap to limit the amount of spending by Formula One
teams,
the amount was not agreed upon and the budget cap idea was dropped.
Instead, costs will be brought down by an almost total ban on in-season
testing, a forced reduction in wind tunnel
usage, the sharing of more data during race weekends, and the doubling
of minimum engine lifespan: the engine will have to last for three
races, instead of two in 2008.
Each driver will be limited to a maximum of 8 engines throughout
the season, in addition to four engines for practice/testing purposes.
To aid improvements in reliability, the engines will be detuned from
19,000RPM to 18,000RPM.
On 27 January 2009, the FIA announced that the rule stating that
the pit lane is closed during a Safety Car period will be scrapped in
2009. The rule was introduced in 2007 to avoid people rushing back to
the pits to refuel, possibly speeding through a danger zone, but
software has been successfully developed to solve this problem.

makin bertambah2 pula undang f1 ni kan....

Subject: Re: F1 vehicle 2009 rule 1/4/2009, 5:58 pm

disebabkan economy dan improve safety feature. tapi rule ini ditukar supaya overtake advantage bertambah, tidak macam dulu susah overtake.

yakan bnyk sudah berubah aerodinamik keta pun makin cntik sudah skrg

Subject: Re: F1 vehicle 2009 rule 1/4/2009, 6:18 pm

bukan, saya rasa makin simple sudah. tidak macam dulu banyak FIN. wing belakang lebih kecil, dan lebih tinggi. wing depan makin lebar sampai hujung tayar, dulu sampai setengah tayar saja

malaysia msih ada ka dlm saingan F1 ni...?

Subject: Re: F1 vehicle 2009 rule 2/4/2009, 12:30 am

ada, next circut di malaysia, boleh dikatakan malaysia adalah negara yang paling panas untuk F1. ini hari ahad, 4 april qualifying, 5 april race.
