The new Formula 1 rules for 2005
Posted: Mon Feb 07, 2005 10:05 am
As the season draws closer, we keep hearing about the new regulations and how they may effect the racing this season. Here are the main points:
Long Life Engines:
Engines must last for two consecutive events. If an engine is changed in practice or first qualifying (Saturday) then a driver will drop 10 places on the starting grid and may not use another engine until the end of the following event.
If an engine is changed after the first qualifying but before the race then the driver will start from the back of the grid.
The FIA will attach seals to the engines to ensure no significant parts can be rebuilt or replaced. Additional seals will be attached between the 2 races to ensure the engine cannot be run.
Aim: To reduce engine power. Both peak and average power will be less than for an engine with a shorter life.
Tyres:
One set of tyres for both qualifying sessions and the race.
Basically from the first qualifying on Saturday the driver cannot change tyres unless it rains. The only time a driver may change tyres under dry conditions is for a punctured or damaged tyre (also if there is a genuine safety reason), in that case the driver cannot refuel at the same time.
Aim: Lower cornering speeds, longer braking distances, less marbles. A tyre which must last 350 km rather than 80 km will have less grip, reducing cornering speeds, increasing braking distances and possibly producing less tyre debris or ?marbles?.
Aerodynamics
Changes to the bodywork includes raising the front wing, bringing the rear wing forward, reduce the diffuser height and cut back the bodywork in front of the rear wheels.
The aerodynamic changes will reduce the downforce by 25 - 30% of 2004 levels.
Aim: Reduction in corner speeds. Lower downforce will reduce speeds, particularly in fast corners, and slightly increase braking distances, while the small reduction in drag will have a minimal effect on straight-line speeds
New Qualifying Format:
Saturday Afternoon Session (13:00 to 14:00 )
Single lap qualifying with the cars going out in the reverse order of their finishing positions at the previous race.
No restrictions on fuel load
Sunday Morning Session (10:00 to 11:00 )
Single lap qualifying with the cars going out in the reverse order of the qualifying on Saturday (fastest car on Saturday goes out last on Sunday)
Session to run with race fuel load. (no refuelling allowed prior to the start of the race)
Times from the two sessions are added and the grid is determined with the shortest aggregate time on pole.
