The Brit’s 1:10.099 was the first time the NIO 333 team has topped a session since Oliver Turvey’s pole position in Mexico City in 2017.
Stoffel Vandoorne was fourth ahead of Sam Bird with Wehrlein and Ticktum’s teammate Sergio Sette Camara in seventh.
Rene Rast was eighth ahead of Jake Dennis and Jake Hughes, who completed the top ten.
Throughout the session Turns 16 and 17 became problematic for some drivers, with Max Guenther and Lucas Di Grassi brushing the wall, however Nico Mueller lost the rear of his car and parked it up. It is unclear whether Mueller’s car will be ready for qualifying.
