"The car felt fantastic, I could have done a load more laps - it's just frustrating that the results don't reflect that," Chilton said. "I made an okay start and defended my position, but the track narrows so quickly here I got squeezed and lost out. Everyone knows it's hard to pass here, and I struggled to make up the places afterwards."
After finishing in eighth place on Friday, Trident's Stephane Richelmi will inherit pole position for Saturday's sprint race on Saturday afternoon at 4.10pm (3.10pm BST) following the qualifying session for the F1 Grand Prix of Monaco.
"I made a great start. I recovered a couple of positions and was behind [Rapax's Tom] Dillmann," said the Monaco native. "I was faster than him but passing at Monte Carlo is almost impossible without a mistake from your opponent."
The Trident team put in a "perfect both in terms of speed and timing," leaving Richelmi with the opportunity to go on the attack in the second half of the race - which paid off.
"I pushed really hard while profiting from the fresh tyres," he said. "I'm extremely happy because going from 14th to 8th is a great result on this track. I hope for a positive ending tomorrow in Race 2. A good start will be key".
His fellow Monegasque, Coloni's Stefano Coletti, tried a completely different strategy - coming out on the prime tyres and sticking on the same set until just four laps before the end. It meant that he was running well up in sixth place from 12th on the grid, and might have been better had he not been held up by slower traffic emerging from the pit lane earlier in the race. In the end, he had to settle for the final points position in tenth.
"Despite our strategy to postpone the pit-stop, tyres wear was minimal as confirmed by fact that the fastest lap that was set at lap forty-one," he pointed out. "Traffic slowed me down in some phases but it is something that one as to account for in Monaco.
"The car was absolutely perfect today and it allowed me to push since the start," he added. "The same pace in qualifying would have probably given me a different result today."
Racing Engineering's Fabio Leimer was even more frustrated and disappointed at the end of the day, having once again been pit by a drive-thru penalty during the course of the race, a recurring theme of his 2012 GP2 season so far. Leimer explained that the penalty had arisen because of early contact with the Barwa Addax car driven by Josef Kral.
"At the start I tried to go towards the left, but this didn't work as Kral had a bad start," he explained. "I had to move towards the inside at turn one and Kral pulled over as well. I touched him with my front wing and lost a part." The collision left Kral out of the race.
