Col de l'Ospedale - Briton Chris Froome destroyed the field to win the final stage and the overall title at the Criterium International as Team Sky completed a dominant one-two on Sunday.
The Tour de France runner-up attacked with 5.5km remaining on the climb to the Col de l'Ospedale, leaving team-mate and then race leader Richie Porte trailing in his wake.
Sky, who have been criticised for their defensive tactics, drew clear of the peloton on the 14.1km ascent.
Paris-Nice champion Porte, who had snatched the yellow jersey after his victory in Saturday's 7km time trial, counter attacked and managed to take second place on the day, 27 seconds behind Froome.
He finished second overall, 32 seconds adrift of the winner.
Froome has made this year's Tour de France his main objective after playing second fiddle to Bradley Wiggins in 2012.
He has shown that he has what it takes to lead the British outfit by winning the Tour of Oman as well as finishing second in the Tirreno-Adriatico.
Australian Cadel Evans, who is still hopeful he can get back to the top, was dropped on the final climb with 10km remaining.
American Tejay van Garderen, his BMC team-mate, also struggled to respond to Team Sky's pace and was third overall, 54 seconds adrift.
Luxembourg's Andy Schleck, who has been in terrible form since crashing out of the Criterium du Dauphine last June, was part of an early break but was reined in by the peloton before the final ascent.
The peloton returns to Corsica in three months for the start of the Tour de France on June 29 from Porto Vecchio.
