Red Bull drivers Daniel Ricciardo and Sebastian Vettel will start from the back of the grid in Abu Dhabi after both cars failed a front wing deflection test.
Ricciardo had qualified fifth just ahead of Vettel.
“Following the decision of the Stewards regarding the front wings on both our cars (Car 1 and Car 3), we are disappointed that we have been singled out for a front wing deflection test when it is clear that other teams are interpreting the rules in a similar fashion,” Red Bull said in a written statement.
“The team accepts the decision of the Stewards and will start the race from the back of the grid.”
The disqualification moves Danill Kvyat up to fifth, matching the Toro Rosso driver’s best performance in F1 qualifying (he also qualaified fifth in Russia), with McLaren’s Jenson Button beside him on the grid in sixth.
McLaren’s Kevin Magnussen and Toro Rosso’s Jean-Eric Vergne move into the top-10.
