Solow took his winning sequence to nine when recording his fifth successive Group One victory in the Queen Elizabeth II Stakes at Ascot.
Freddy Head's talented grey was never far off a ferocious pace set by Elm Park and Kodi Bear before stamping his authority in the top European mile race.
Maxime Guyon pressed the button and the 11-10 favourite went away to score comfortably by three-quarters of a length. Belardo (33-1) was a length and a half away with Gabrial a further length and a half away in third.
Aidan O'Brien's Gleneagles took his chance after connections had thought long and hard before allowing him to run, but he never looked like justifying their tough decision on far from ideal ground.
Guyon said: "It's amazing, it's very easy - he's the best. He loved the ground and he can go anywhere, in front or behind. For a jockey, it is very simple. It is not easy to win a Group One at Ascot and I have won two with him."
Head said of his winner, who is two from two at Ascot having won the Queen Anne at the Royal meeting: "He's very special. To be able to keep his form like that all year with all those journeys he's made and every racecourse.
"He's very sound, he's easy to train and does whatever you want at home. He's bred to get much further so earlier in his career I tried to turn him into a stayer and then he got beat. He was working so well at home so I put him over shorter."
O'Brien said of sixth-placed Gleneagles: "He had been trained for four races and had not had a break all summer. We knew it was going to be tough to come here and especially in the ground.
"If I had the choice again I would probably say not run him, like we did the other times. We had our eye on the Breeders' Cup Classic and if he was going there he had to run. We took a chance and the race was a little messy. He's a fast-ground horse.
"About the Classic we'll have to see how he is. Everyone will talk about it and decide what's best.
"There were a lot of pros in running him but it didn't work for us on the day. He seems to be fine after it and we'll see what he's like in the next few days."
Belardo's trainer Roger Varian was thrilled with another good effort from this three-year-old, who came back to form recently at Newmarket.
He said: "It was a great run and we're pleased with that, he ran very well in the Challenge Stakes at Newmarket from where he had to come from, but he needs riding like that. Being 'cold' early on - that's how he won a Dewhurst.
"We would have preferred to have won, but we are pleased that he put up a high-level performance and I think he has made a case for staying in training next year.
"I don't think there is anything else this season for him, but James Doyle thinks he will get further. It was a shame they went slow early on, but we are delighted with the horse as it reminds people of what a talent he was last year."
Gabrial was sent off a 66-1 chance and his trainer Richard Fahey said: "He's just a wonderful horse, they got racing around three out and that probably helped as some of them walked home. He gets the trip very well and that will keep the Dr (Marwan Koukash, owner) happy!"
