Qualifying: Qualifying will be divided into two, one-hour sessions on Friday and Saturday, instead of one hour on Saturday. Drivers will get one "flying lap'' with cars running one at a time. Friday times will determine the order of Saturday's session, with the fastest car going last. The starting grid for Sunday's race will be based on Saturday's times. Team will not be allowed to refuel after Saturday qualifying for Sunday race.

Practice: Three teams -- Renault, Jordan and Minardi -- have signed up to the new practice schedule. They will be allowed an extra two hours of practice on Friday, but will be allowed just 10 days of private testing during the season. The other seven teams will have one hour to test on Friday before qualifying.

Driver's aids: Traction control and electronic gearboxes will be outlawed beginning with the British Grand Prix in July. Launch control, which helps drivers in starting from a dead-stop, will be banned beginning with the same race, provided all teams can equip their cars with manual clutches.

Telemetry: Pit-to-car telemetry, which allows teams to change the settings on a car during a race via computer, has been eliminated. The FIA proposes car-to-pit telemetry be banned from the start of the 2004 season.

Points: The top eight finishers will earn points instead of only the top six. Scoring will be 10, 8, 6, 5, 4, 3, 2, 1. Old system was 10, 6, 4, 3, 2, 1.

Radios: Radio transmissions between the driver and team will continue but the communications must be open to the governing body, FIA, and broadcasters.

Spare cars: Teams will be allowed to use a spare car if the race car is damaged beyond repair. If a car fails before the start of a race or cannot be used after a race has been stopped during the opening two laps, teams can use the spare car but the driver will start from the pit lane.

Team orders: Team orders that interfere with a race result have been banned.
