Lady Aurelia just lasted out the six furlongs as she retained her unbeaten record in the Darley Prix Morny at Deauville.
Wesley Ward's flying machine showed tremendous speed from the start and was soon in command under Frankie Dettori, who was winning the race for the third year running.
She had left a big impression with her victory in the Queen Mary Stakes at Royal Ascot over five furlongs and her class saw her through the extra furlong as the 3-10 favourite triumphed over the colts to claim Group One spoils.
The Freddy Head-trained Alrahma was second at 71-10, with Aidan O'Brien's Peace Envoy third.
Al Johrah was fourth and Tis Marvellous, trained by Clive Cox, last of the five runners.
Speedy Boarding (43-10) gave Newmarket trainer James Fanshawe his second victory in three years in the Darley Prix Jean Romanet
Successful with Ribbons in 2014, Fanshawe delivered Group One honours again with Speedy Boarding, who was recording her first win at the highest level.
Sayana made the early running until Irish raider Bocca Baciata went on just after halfway.
However, Jessica Harrington's challenger could not keep up the gallop and she weakened in the final quarter-mile.
Speedy Boarding was produced with a well-timed run by Freddie Tylicki and went on to win in good style from Andre Fabre's Ame Bleue (21-1) with the David Smaga-trained Steip Amach (9-1) third.
Nearly Caught (11-2) was never headed as he came home without seeing another rival in the Prix Kergorlay.
The Hughie Morrison-trained six-year-old ran the opposition into the ground as he grabbed the Group Two spoils in emphatic fashion.
Umberto Rispoli had employed similar tactics when successful over the course and distance in a Listed contest a month ago and the duo were soon seen to good effect again.
Though the pack finally started the close, Nearly Caught was still three-and-a-half lengths to the good at the line.
Candarliya, Alain de Royer-Dupre's even-money favourite, was second with Trip To Rhodos (13-1) third.
