Felipe Drugovich topped a frantic Practice session at Monaco for MP Motorsport ahead of Ralph Boschung and Dennis Hauger.
The sole Formula 2 Practice session got underway at Monaco on a bone dry circuit as plenty of the drivers completed installation laps.
A flurry of drivers set impressive lap times in the opening stages including the returning Boschung who set 1:26.741.
The championship leader Drugovich quickly usurped the Swiss driver’s effort after getting balked by Roy Nissany at the Swimming Pool chicane on a previous lap.
The times continued to tumble as Drugovich found yet more speed becoming the first driver to go below the 1:24s with a 1:23.845.
With half an hour to go, Juri Vips got his weekend underway for Hitech with a 1:25.221 as all 22 drivers continued to attack the streets of Monaco.
Jake Hughes set the quickest time for Van Amersfoort with the red soft tyre the compound of choice for the start of the 45 minute session.
Vips went down the escape road at Sainte Devote after locking up both front tyres but the Estonian avoided the barrier and continued in the session.
Dennis Hauger improved to third place for PREMA on his first visit to Monaco before his 1:23.253 was fractionally beaten by teammate Jehan Daruvala.
Boschung continued his impressive form in Practice raising the bar even higher with a 1:22.336 to go half a second clear of Hughes in second place.
Hughes went straight on at Antony Noghés which destroyed his flying lap, but he found reverse gear and subsequently set more quick lap times.
The grippier super soft tyre was bolted on by most teams for the final 15 minutes of Practice including Drugovich.
The Brazilian showed his prowess with a 1:21.817 to go into P1 ahead of Boschung and Marcus Armstrong.
Marino Sato locked up at Sainte Devote and had to turn around in the run off area before rejoining the circuit with four minutes to go.
Norwegian driver Hauger found yet more time with a 1:21.637 despite an alarming slide at Anthony Noghés before being beaten by Drugovich.
At the chequered flag, Drugovich topped the timesheets ahead of Boschung, Hauger, and Hughes.
Liam Lawson finished fifth for Carlin ahead of Doohan, Daruvala, Sargeant, and Verschoor as Pourchaire rounded out the top 10.
