Every year the bosses of Formula 1 change some of the sport's rules to try to make the racing more exciting.
For 2010 there are lots of changes, and here are some of the biggest:
Number of cars
The number of cars allowed to take part in a race has been increased from 24 to 26.
Because there are more cars, a new points system has been brought in too.
Drivers will get 25 points for finishing first, 18 for finishing second, 15 for finishing third, 12 for fourth, 10 for fifth, 8 for 6th, 6 for seventh, 4 for eighth, 2 for ninth, and 1 for tenth.
Lots of new rules have been brought in to reduce the costs for the teams.
Refuelling during the race is to be abolished for the first time since 1993 and teams will not be allowed to make as many changes to their cars mid-season.
Teams won't be allowed to bring as many workers to races and their factories will have to close during the F1 summer break.
They'll also have to use less sets of tyres on race weekends.
