Stewards said in a statement at the season-ending Abu Dhabi Grand Prix that the governing FIA’s media delegate had reported the pair for “the use of certain language” in the Nov 16 conference.

The Las Vegas stewards had been unable to conduct a hearing after the race and delegated their authority to the Abu Dhabi stewards.

“The purpose of the hearing will be to determine if there is a breach of Article 12.2.1.f of the FIA International Sporting Code and, if so, what if any action should follow,” the stewards said in a statement.

The article covers “any words, deeds, or writings that have caused moral injury or loss to the FIA, its bodies, its members, or its executive officers, and more generally on the interest of motorsport and on the values defended by the FIA.”

Vasseur used profanity in an angry response to a question after Carlos Sainz’s Ferrari was wrecked by a loose drain cover during the aborted first practice session.

Wolff also swore at a suggestion that the cancelled practice was a “black eye” for F1.

Mercedes and Ferrari are fighting for second place in a championship dominated by Red Bull, with just four points separating the two teams.
