Dalakhani justified his status as pre-race favourite, powering home in a thrilling fast finish to win the Prix de l'Arc de Triomphe at Longchamp.
The French Derby winner - ridden by Christophe Soumillon - had to come in from stall 14, wide out on the right, and held off a brave challenge from Mubtaker.
Ireland's High Chaparral finished third in the 13-horse race for the second year in a row.
"It's a race I wanted to win throughout my apprenticeship and it's unbelievable to ride a horse like him," said 20-year-old Soumillon.
"He's a real champion and I love him so much."
At the seven-furlong mark Dalakhani found himself nestled at the back of the pack while his pacemaker Diyapour did his job up front.
It was Mubtaker - ridden by Richard Hills - who pushed for home first, surging into the lead on the false straight.
But the Aga Khan-owned Dalakhani showed his class as he poured on the pace, despite the soft ground, and claimed victory by three-quarters of a length.
"I was worried about the ground as he hadn't won on it since he was a two-year-old, but he proved he could handle anything," said the Aga Khan, who won his third Arc.
It was a disappointing day for Irish trainer Aidan O'Brien who watched as High Chaparral toiled back in third.
The four-year-old never really challenged for the lead and jockey Mick Kinane revealed that the horse does not find the Longchamp circuit to his liking.
"I started to struggle at a vital point turning for home, but he laboured a little bit on the heavy ground," said Kinane.
"Maybe it doesn't suit him round here. He seems to be better going left-handed."
O'Brien admitted he has yet to decide whether High Chaparral will travel to America to defend his Breeders' Cup title.
Frankie Dettori's bid to win his third Arc in a row was dashed when his mount Doyen finished back in fourth place.
Kris Kin, winner of the Epsom Derby, did not show any form finishing well down the field.
