Wild Illusion caused an upset in the Total Prix Marcel Boussac at Chantilly.
Freddy Head's previously unbeaten filly Polydream and Aidan O'Brien's Irish challenger Magical dominated the market for the Group One contest.
Wild Illusion, trained by Charlie Appleby for Godolphin, made a winning debut at Yarmouth during the summer before finishing third in a Group Three at this venue a month ago.
James Doyle's mount tracked the pacesetting Soustraction for much of the way before taking over entering the final two furlongs.
After being ridden with restraint, Polydream finished strongly down the outside of the field but it was too late as Wild Illusion kept her at bay comfortably. Mission Impassible narrowly beat Magical to third place.
Wild Illusion was added to the field earlier this week at a cost of 21,600 euro. Doyle said: "We had to supplement her and that was Charlie's doing - he was very confident today.
"She's a relentless galloper and I think having been round here before stood her in good stead."
Appleby was winning the race for the second successive year following the victory of Wuheida 12 months ago.
"I'm delighted. The improvement that she'd shown since her last run was enough to justify supplementing her," said the Newmarket-based trainer. "I spoke to His Highness (Sheikh Mohammed) in depth about it and he said if we were happy with the horse we should go for it.
"We were delighted with her at home and we put the cheekpieces on, just because we felt going up to this level we wanted to keep her concentration up, nothing more than that. You could see there she's as genuine as the day is long.
"She's a lovely filly with a great pedigree and we'll put her away for the winter now. We can live the dream until next spring.
"I'm sure she'll be in the reckoning for the 1000 Guineas, but on the basis of that, she's a relentless galloper and staying is going to be her thing."
