This game was over bar the shouting by half-time after a brace from both Felipe Caicedo and Robinho and Stephen Ireland rounded off the rout late on.
Caicedo rewarded Mark Hughes' decision to award him a rare start with two early goals, adding to his efforts against Racing Santander and West Brom in recent days.
Hull's early pressure forced Joe Hart into a couple of tidy saves from Marlon King and Geovanni's 35-yard free-kick in the 33rd minute, but in reality the visitors were so outgunned that Hull boss Phil Brown hauled off George Boateng and put on Nathan Doyle in an effort to shore up the Tigers' defence, which was being mauled by the combined forces of Robinho, Ireland and Shaun Wright-Phillips.
Hull had already faded by the time Robinho's second goal had gone in and Geovanni went into the referee's notebook for a wild lunge at Pablo Zabaleta.
The early jitters may have made the home side a little cautious but they soon got into their stride. Richard Dunne escaped from the City defence and set Robinho free down the left.
The Brazilian saw Ireland in space and sent in a crossfield pass that Ireland sidefooted into the path of the oncoming Caicedo, who made no mistake from six yards out and rippled the roof of the net.
Ireland was again the provider 11 minutes later when Wright-Phillips set him free for another run up the right flank. He looked up and crossed and once again found Caicedo arriving in time to make it 2-0.
If Caicedo's brace wasn't enough to win the game then Robinho put City out of sight.
Ireland made it a hat-trick of assists when he won the ball on 28 minutes and laid it off to Robinho, whose mazy run left Michael Turner dizzy and comprehensively beaten when he shimmied and fired past Boaz Myhill to make it 3-0.
There was a suspicion of offside when Elano put Wright Phillips through, but his cross from the right to Robinho allowed the Brazilian to lose his marker and effortlessly score City's fourh goal.
It was game over and Brown certainly had words to say at half-time as he berated his team on the pitch for several minutes.
Elano's free kick 76th minute was deflected on to the woodwork by Craig Fagan, but Fagan was to provide a nothing more than a mere consolation minutes later when he tapped in following confusion in the home defence after Hart palmed Daniel Cousin's cross away.
City couldn't resist having the final say, however, and Ireland capped a man of the match performance by scoring City's fifth, after Robinho's cross was laid on a plate for him following Elano's splendid approach work.
Not even a hint of an own goal in the 84th minute, when Dunne sliced a clearance into Hart's hands, could make this anything less than a resounding win.
