Estrange looked a filly out of the very top drawer when running away with the Betfred Nifty 50 Lester Piggott Fillies' Stakes (Group 3) (Formerly Known As The Pinnacle Stakes) at Haydock on Saturday.
David O'Meara's Cheveley Park-owned four-year-old had been off the track for 203 days but she travelled all over her rivals under Danny Tudhope.
The striking grey also had to prove herself on better ground after winning twice on soft as a three-year-old, but she glided across the faster turf as she landed odds of 13/8 by four-and-a-quarter lengths from the 11/8 favourite Shaha.
Paddy Power cut the daughter of Night Of Thunder to 33/1 from 66s for the Prix de l'Arc de Triomphe on the back of the victory.
O'Meara said: "We thought a lot of her before she won at Goodwood last year. I shouldn't have run her at Yarmouth, but she won at Doncaster and she looks like she's come back better than ever this year.
"She's a pure queen. Nothing fazes her which is probably a great asset in a racehorse. She doesn't pull, she's a dream for me to train and for Danny to ride.
"She's in the Pretty Polly in Ireland as well. She goes on soft ground, we'll probably stay away from very fast ground.
"It would be amazing to think we could end up in the Prix de l'Arc, but there's a lot of work between now and then."
Tony gets it on the Bob
Ten Bob Tony survived a stewards' inquiry to land the Group 3 Betfred John Of Gaunt Stakes at Haydock for Ed Walker and William Buick.
The four-year-old was returning after 203 days off the track having been gelded and he just prevailed in a tight finish from Kinross after the pair came together.
The stewards judged the result was fair after Ten Bob Tony was first past the post by a head, Kinross so game in second under a penalty.
Volterra was a length-and-a-half behind the pair in third with the well-fancied Audience and Alyanaabi both disappointing further down the field.
