Godolphin struck double Group-race gold as Vancouverite and Zibelina lifted the two feature events at Deauville on Thursday.
Vancouverite was part of a classy line-up for the Group Two Prix Guillaume d'Ornano, with Richard Hannon's Havana Gold one of three previous Group One winners in the race along with Morandi and Silasol.
Havana Gold was stepping up to 10 furlongs for the first time and Mickael Barzalona was happy to settle in third with Morandi racing just upsides as Plaine Monceau set the early gallop.
The latter kept up a good pace until around two and a half furlongs out when the field began to reel him back in and the leading players went for home.
Havana Gold had every chance but began to toil in the last furlong or so while the Andre Fabre-trained Vancouverite kept finding more for Pierre-Charles Boudot to go on and win by a length and a quarter from stablemate Pilote.
Zhiyi took third while Havana Gold could finish only fifth.
Vancouverite could now have his sights raised with a crack at the Prix de l'Arc de Triomphe at Longchamp on 6 October a possibility.
Godolphin's racing manger Simon Crisford said: "He won well and he showed a good turn of foot.
"He will come into the Arc picture now, but I don't know if he will run before. We will see how he comes out of this and make plans nearer the time."
David Redvers, racing manager to owner Qatar Racing, felt Havana Gold did not see out the trip and pinpointed the Prix du Moulin back over a mile at Longchamp on 15 September as a likely target.
Fabre later saddled Destruct to win the Listed Prix Michel Houyvet, in which Jo Hughes' London Bridge was a game fourth after trying to make all.
Zibelina had earlier initiated the Godolphin double in the Group Three Prix de Lieurey.
The Dansili filly was having just her third start having run out a 10-length winner of a Newcastle maiden event before going on to Listed glory at Newmarket last time.
Taking the next step up the ladder for Charlie Appleby, Zibelina was prominent throughout under Barzalona as Shenliyka cut out the early pace.
As the field turned for home, Barzalona gave his mount the signal and she began to pull clear.
Table Ronde emerged to reel her back in but Zibelina had a neck in hand at the line with Siyenica back in third.
Zibelina is also set to test her mettle at Group One level, with Crisford identifying the Kingdom of Bahrain Sun Chariot Stakes at Newmarket on 28 September as her intended target.
Hannon had earlier sent out the Frankie Dettori-ridden Shamshon to win the Listed Prix de la Vallee d'Auge.
The Sheikh Joaan Al Thani-owned colt made a successful debut at Sandown last month and followed up with a stylish win in this event over just shy of five furlongs.
He challenged down the middle of the track and moved three-quarters of a length clear of Aventure Love with Wesley Ward's American raider Here's Johnny showing up prominently before fading into fourth.
