Nissan e.dams’ Sebastien Buemi topped the second practice session ahead of the Sanya E-Prix as Nissan made it a clean sweep of practice sessions.
Buemi had an off at Turn 3 in the latter part of the stages as he took too much speed into the left-hander and hit the wall.
He was able to head back to the pits for the car to be checked out and was able to re-join the action.
After Buemi’s team-mate Oliver Rowland topped the first session, it was the Season 2 champion’s turn in the second session as his team-mate finished third.
BMW i Andretti Motorsport’s separated Buemi and Rowland after posting a time of 1m07.397s, just over a tenth behind Buemi.
Mahindra’s Jerome d’Ambrosio was fourth and just 0.003s behind Rowland, posting a time of 1m07.456s.
Reigning champion Jean-Eric Vergne was fifth ahead of Hong Kong winner Edoardo Mortara in sixth.
Jaguar’s Mitch Evans and Audi Sport Abt Schaeffler’s Lucas di Grassi set the exact same time of 1m07.578s to finish seventh and eighth.
Dragon Racing duo Felipe Nasr and Jose Maria Lopez rounded out the top 10.
The top 10 drivers were separated by just 0.369s at the end of the session with eight manufacturers in the top 10.
Championship leader Sam Bird was 11th with Hong Kong polesitter Stoffel Vandoorne just behind.
Felipe Massa headed Andre Lotterer for 13th place with Daniel Abt in 15th and Robin Frijns, running the same Audi powertrain, in 16th.
Frijns was the last driver to be within a second of pacesetter Buemi.
NIO drivers Tom Dillmann and Oliver Turvey followed Frijns with Nelson Piquet in 19th. Piquet had to stop during the session to have the batteries changed in his halo device.
Alexander Sims was 20th with Gary Paffett and Pascal Wehrlein round out the field.
Both Paffett and Wehrlein were on fast, full power laps when they clipped the wall on the exit of Turn 6.
