The FIA is in talks with Ferrari to discuss whether or not the team can continue to use its new rear wing for the remainder of the Spanish Grand Prix weekend.
The revised rear wing that ran in Friday practice features a higher than normal Gurney-flap on the rear, which Ferrari has managed to introduce through an interpretation of the slot-gap separator regulations. FIA technical delegate Charlie Whiting said on Friday that the governing body was looking into the wing design – and would decide before final practice whether it thinks the concept is legal.
"We are aware of the developments on the Ferrari wing and we are discussing them with them," explained Whiting. When asked whether the team would be able to keep it on its car, Whiting said: "That depends on what we decide tonight. It's a very clever interpretation of the rules and we have got to decide whether it's a good interpretation of the rules. It will be clear tomorrow."
Whiting said that the issue with the rear wing related to the way that article 3.10.3 allows the height measurement of the rear wing not to include the slot supports.
"It is article 3.10.3, which deals with slot gaps separators, the devices which are normally just vertical, which keep the distance between the profiles constant," he said. "The fact that the separators have to totally encircle the profiles ensures the profiles remain the same.
"We had an issue with changing profiles a few years ago. The separators can't be more than 200mm apart. It's an alternative interpretation of that rule that we are currently discussing."
