Outstanding miler Sendawar will now head for Ascot's Queen Elizabeth II Stakes later this month after a scintillating victory in the Emirates Prix Du Moulin De Longchamp yesterday.
But the big disappointment of the race was Godolphin's Sussex Stakes winner Aljabr, who led for a few strides in the closing stages under Frankie Dettori before fading quickly into fourth place, beaten nearly four lengths by the winner.
Sendawar, whose connections said may stay in training as a four-year-old, earned some strong tributes for his talent and temperament from both jockey and trainer.
Winning rider Gerald Mosse said: "We know he is very good. He must be as he won this race in a few strides."
Trainer Alain De Royer Dupre commented: "He is such a marvellously calm horse that he actually laid down in his box and slept on his way to the races today."
Sendawar, for whom this was a third successive Group 1 win over a mile, was returned a heavily backed 4 to 5 favourite.
At the post the winner had one and a half lengths to spare over fast-finishing runner-up Gold Away with Dansili a further head away in third.
Aljabr's stable-companion Fly To The Stars cut out much of the early running but was struggling in the straight and only beat one of his eight rivals home.
Trainer Saeed Bin Suroor said of Aljabr's run: "That was disappointing considering he has been working really well. He did not blow much after the race, and we will have to take him home and check him out."
Sendawar's owner, the Aga Khan, was back in the winner's enclosure when Tajoun, also trained by Royer-Dupre and ridden by Mosse, survived a stewards' inquiry to win the Prix Gladiateur.
Godolphin's Pozarica finished third, and the John Gosden-trained Jaseur beat just one of his six rivals home in the 14 1/2-furlong Group 3 race.
