Markus Pommer pipped Christopher Zanella to top spot in the second FIA Formula Two practice session at Brands Hatch, as he bounced back from an early end to the morning session.
The German driver had managed just seven laps before stopping on track in the first session, subsequently ending up with the slowest time.
But at his first race weekend at the Kent circuit, the 21-year-old bettered Zanella's effort by just 0.019 seconds at the end of the session.
Zanella had earlier dislodged fellow Swiss driver Alex Fontana from top spot, and it was Fontana who finished up behind Zanella in third with another compatriot Matheo Tuscher in fourth.
Max Snegirev used his knowledge of the circuit from his days in Formula Palmer Audi and British F3 to record the fifth fastest time, only six tenths off the pace.
The Russian edged out a trio of British drivers, with Dino Zamparelli finishing up as the top home racer ahead of championship leader Luciano Bacheta and Hector Hurst, who'd been the second quickest in the morning.
Slough-born Zimbabwean Axcil Jefferies was ninth, with Iranian Kourosh Khani joining his fellow Formula Renault BARC graduates Zamparelli and Hurst inside the top ten.
Plamen Kralev was 11th, while Mihai Marinescu could only manage 12th after going three tenths quicker than anyone else during the morning session. Kevin Mirocha was 13th, ahead of Mauro Calamia, Daniel McKenzie and David Zhu.
