Causes and effects of the 2010 rules We are now a few hours of the start of the first F1, then worth review the rule changes that characterize this season . Like every year, the FIA \u200b\u200btries to shuffle the cards on the table, so that means making the most spectacular gp; facilitate overtaking, etc. level performance.
In fact, only sometimes these goals are achieved. But we recall briefly the changes to Regulation for this 2010 season and try to understand what should be the most immediate effects of the main new .
SCORES
Change this year, the scoring system. Now they will be 10 riders who will take points at the end of the race, and not more than 8. The winner will receive a greater distance than the latter. First place will be 25 points, 18 per second, and then climb up to the 10th ranked according to this ranking: 25, 18, 15, 12, 10, 8, 6, 4, 2, 1.
Effects: should increase as the battle on the track. Pilots are led to look with great interest the victory, but also a useful position in the rear.
SUPPLIES
This year will be banned. The cars then have to board from the start, all the fuel needed to reach to the finish.
Effects: this new regulation has already greatly influenced the design of the cars, which now houses a reservoir more than doubled since last year. Weight, length and dimensions of cars have increased, which is why the cars of 2010 are born this radically different from those of 2009. It will be essential for all the teams to maximize consumption. Who can have an engine that consumes less will start with less fuel load, and then lighter and faster than the others (the outset). The influence of the weight of gasoline also will impinge on performance and durability of the tires. It will be important to manage the pit stop and then the stint (fractions of a race to stop another) as long as the same set of tires will have to equip a car that will run in different conditions of constant weight (due to consumption fuel).
TIRES
The front tires are narrower. The width of the tread their passes from 270 to 245 mm. 
Bridgestone, the sole supplier of tires for Formula 1, now equips teams with tires whose specific compounds have been designed specifically as a result of new regulation. The first element to take into account the weight: the car tires 2010 will support much heavier.
Effects: the way a car (especially under the chassis, aerodynamics and suspension) will consume the tires will be even more crucial than ever before. Especially for those who start in the first 10 positions, forced to use the same coverage of the qualifying session. Since it does not make pit stops for refueling the cars will stop only to change tires. That's the choice and tire management becomes critical to the strategy of the entire race.
ROLES
more pilots will be eliminated between Q1 and Q2, the first two Saturday's qualifying sessions. Come out of the last seven games, no more than the last five as last year.
Also, those at the end of the qualifications listed in the first 10 positions will not be able to change tires and will face the race with the same tires the last qualifying session.
Effects: who finishes behind in qualifying, leading to an advantage over the first decade, which has already used tires. Another quirk to reshuffle the cards. It will also be interesting to see how cars in qualifying, will have a set-time (tank nearly empty), while the next day will begin with the same attitude, a race fully fueled.
PIT-STOP
devices will be prohibited to speed up the exchange tires, very very quick this year, given the lack of supply. It was also the potential risks associated with extreme speed when changing tires have been removed the covers of these wheels last year.
Effects : pit-stop will still be fast, but we hope this does not mean little attention in setting the wheels, as happened last year to a mechanic on the car of Alonso's Renault (for the mistake that led the wheel is the French team suffered a penalty). Even so the cups were removed the wheels, which had been a clear aerodynamic function. But here the Ferrari has already mounting, instead of Appendices now prohibited on the wheels; a ring, double ring nut central spinner.
NEW RIDERS
If a team decides to replace a pilot during the course of the season, the driver who takes over (as last year) is unable to carry out preliminary tests on the car entered the league. Unless he / she is a pilot who has never raced in F1, or that there runs at least two years. In this case, will undertake a day of testing to be carried out in a circuit that is not part of the F1 calendar.
Effects: so you can avoid cases such as (for example) Alguersuari who last year replaced Bourdais, without any pre-test (which is dangerous to himself and others). Or how to Schumacher in the Ferrari predicate to return to replace the injured Massa, had to try with F2007 at Mugello.
KERS energy recovery system would have been foreseen by the FIA, but after the uncertainties of last year, the team decided, by mutual agreement, to help it. A controversial and very expensive so that leaves the stage after only a year old. From 2011 onwards would disappear forever.
Effects : without KERS will be much simpler. A trinket that has diverted giants like Ferrari in 2009 and he did spend 80 million € for more horses for 7 seconds per lap. Superfluous.
