And qualifying has also been changed, so that the cars will now go out in two different groups of 13 cars for 14 minutes each rather than have the entire field rush out and fall over one another, as happened last year to a rather embarrassing degree.
"This is a good move by GP2 because last year was manic with 26 cars as people have to do slow laps to cool down the Pirelli tyres so there is so much traffic," was Palmer's view of the change in qualifying format. "Hopefully this year everyone can have a clean qualifying with half the cars on track."
"I already know this kind of qualifying mode from last year, so it's nothing new for me," said Berthon, who raced here in 2011 in the Formula Renault 3.5 Series. "In my opinion, it is better for Monaco as the traffic management is so important when it comes to setting a good lap time.
"Apart from that, for me as a driver, it doesn't change anything," he added. "The aim is to be at the top of the field, whatever it takes."
