British F3 to add pitstops

Drivers will have to make a mandatory pit visit during an eight-lap window, which will begin at one-third distance during the first 30-minute race of the weekend.

Cars will be required to come to a full stop in their allocated pit apron box, with a team member's 'lollipop' touching the top of a front wheel. Teams will be allowed to work on the cars but pitstops will not be allowed during safety car periods. Penalties will be applied for missing the window, not stopping correctly, or unsafe stops.

The move is designed to better prepare the drivers for GP2 and Formula 1, while also allowing the teams to develop their race strategy skills.

"We want to give the drivers the opportunity to further develop their race skills, and also to give team engineers and drivers the chance to interact more on race strategy," said race director Bernard Cottrell.

"The teams and the drivers will need to be disciplined about their approach to the stops, bringing additional pressures for all concerned, and that will be great training."

If the trial is a success, pistops may also feature at Silverstone in August and the season finale at Brands Hatch, possibly in the 40-minute 'feature' races, depending on feedback from the competitors.

"There is the possibility of using this format at other circuits, such as Silverstone and Brands Hatch, where the pit lane is suitable," said Lisa Crampton, general manager of championship promoter SRO.

"We may in the future select the third race of the weekend rather than race one, but that would be up to feedback from the teams and from organisers.

"The pit-stop plan is part of the continuing development of the series together with FOTA, race director Bernard Cottrell and the entrants to ensure that Formula 3 remains a staple training ground for future leaders in the sport.

"It follows from lengthy research into the best ways to enhance development and racing for both driver and team, and also spectators, without placing financial strain on the teams to upgrade or buy new equipment."
