The second free practice session started with a wet track but no rain pouring on the street circuit, and was eventually topped by Robin Frijns who put in a late-ditch effort to deny Oliver Rowland a second consecutive P1.
In a bit more than two minute-time, the first yellow flag was shown as Edoardo Mortara´s car just stopped on track.
All drivers were running on the edge, using every inch of the track while struggling with track conditions and tyres temperatures. Lucas di Grassi touched the tech-pro barriers with the left rear of his Audi Sport.
With half of the session gone, Gary Paffett of HWA Racelab set a fast lap (1.10.623s) but only a few minutes later he will end up slightly kissing the wall.
As the times continued to fall, Rowland went back on top with a time of 1.10.447s.
The Nissan e.dams driver seemed to be a man on a mission, he even made contact with the rear of Mahindra Racing’s Jerome d’Ambrosio, causing no visible damage.
Three minutes to go and Rowland led with 1.09.478, after swapping fastest lap times with Andre Lotterer.
José María Lopez lost the car touching the wall with the nose of the car, with Pascal Wehrlein locking up and managing to avoid contact with the GEOX Dragon Racing driver. Teammate Felipe Nasr suffering technical issues and finished the session last.
Rowland, Lotterer, Edoardo Mortara, Sam Bird, and Jean-Eric Vergne looked set to be the top five drivers of the second free practice session, but with the final fast lap of the session Frijns put his Envision Virgin Racing machine into the top spot. The final piece of drama came with Alexander Sims making some magic to avoid the wall.
