The FIA has confirmed that at this weekend's British Grand Prix, drivers will be able to activate their movable rear wings (DRS) shortly after Turn 4, what is now known as the Loop.

After races in Montreal and Valencia which featured two DRS zones, Silverstone will feature just one from Turn 5 and then along the 185 mph Wellington straight.

The DRS detection zone is shortly before Turn 3 (Village), like the Wellington straight part of the new Arena section first introduced in 2010.

Aside from the new pitlane entry and exit, necessitated by the building of a new pit and paddock complex, there have been only minor changes to kerbing since 2010.

"The new pits are the biggest difference, and the entry and exit bring new challenges," says race director Charlie Whiting. "The entry is shorter than staying on the circuit, so we will have to ensure that drivers don't use these changes to the pits to their advantage. As for the exit, this is now quite a steep uphill into an extremely fast corner, so it's certainly going to be different. It's going to be quite significant in terms of strategy as there's not too much cost in changing tyres."
