The FIA has opted to drop the second drag-reduction zone for the European Grand Prix after reviewing its effectiveness from last season.
Instead the race will feature the one zone between turns 10 and 12.
Detection has yet to be confirmed but will likely remain in the same place as 2011, just before turn eight where the following driver must be within a second of the car ahead.
As the car approaches the sweeping bend that is T11, they can activate the rear-wing to provide an additional 7-8 kph boost along the straight before the wing automatically closes in the braking zone for turn 12.
