What's the difference between the new season F 1 in 2009 and last season in 2008? Racing, rules and so on. Detailed introduction, thank you.

1, the front alar and the front alar are widened and lowered, and the driver can adjust the angle independently. However, at present, the driver can only adjust it up and down once per lap, which can increase the upward air flow and strengthen the downward pressure, and the driver can make fine adjustments according to the situation.

2. The tail wing is narrowed and improved, so that the surface airflow of the racing car output by the tail wing and the airflow at the bottom of the racing car output by the diffuser will not be mixed to generate turbulence, which will affect the following car and strengthen the overtaking efficiency.

3, bald tires, bald tires will be faster, its grip will increase by 20% than before, but obviously, compared with tires with pits, bald tires wear faster and are easy to blister. At present, when it is used, especially soft tires, it is very easy to bubble. A set of soft tires can actually be used, but it looks like more than ten laps.

4. The original auxiliary fins and small exhaust holes are all cancelled, which means that the auxiliary measures for pressing down are reduced to a very low direction.

5.KERS system will allow the car to have 82 horsepower in 6.5 seconds per lap. Specifically, the energy when the car brakes is collected and stored in the KERS battery. After each lap passes the starting line, it is allowed to be released and cannot be accumulated.

6. Only eight engines can be used in a season, and the speed is limited to 19000 rpm to 18000 rpm.

In terms of competition rules, this year we still use last year's points rules. The voting system of 12 points for the champion of the substation and 9 points for the runner-up failed, and Bernie's medal system for the champion was forced to be postponed until next year because of the unanimous protest of the team.

In terms of driver changes, sebastian vettel, a former driver of Red Bull Team II, was promoted to Red Bull Team I.. The former DC of Red Bull Team 1 was originally prepared to retire, but because the test driver did not have the qualification of super driver's license, he turned to become a test driver of Red Bull Team 1.

In the sponsorship war of Toro Rosso, Bodes won the position of No.1 driver in the team, while new driver Sebastian Bemi won the position of another driver with the sixth place in GP2 and huge sponsorship strength.

To put it simply, Red Bull and Red Bull have three classmates named Sebastian this Monday.
