Silverstone start agreed for new-look qualifying.

A revised qualifying format will be in place for the British Grand Prix, after team bosses hammered out an agreement to replace the derided current system during a lull in the action in Canada.

While exact details have yet to be released, it is expected that a new single session will replace the current pre-qualifying and qualifying runs, with drivers allowed to complete a maximum of twelve laps during the course of an hour. In order to ensure that there is action throughout the session, however, teams will be required to field both cars in two sessions either end of the hour. The best time for each driver from either half will then be aggregated to form the grid. Each competitive portion was initially set at 20 minutes in length, but may be expanded to 25 minutes in order to cut down on the 'lull period' in between.

The current single-car system will continue to operate in both the US and French Grands Prix, which take place over the next three weeks.

"The final version of qualifying procedures was agreed and signed off today, and will be introduced at Silverstone," McLaren boss Ron Dennis confirmed to Reuters during the Canadian round.
