Formula One chiefs are asking fans to help end the search for an acceptable Grand Prix qualifying system.
Qualifying is currently a one-hour session the day before the race
F1 has tried four systems in three years but none has been satisfactory, and now fans are being asked to vote for a solution on www.formula1.com
The first option is two 25-minute sessions with a driver's best time from each combined to determine the grid.
The second sees five cars eliminated after 15 then 30 minutes before a 10- car shoot-out to decide the top spots.
