Sebastien Buemi and Nicolas Post made it a one-two in first practice in Berlin, but they were the only two drivers to do a 200kW lap time.
There were a number of stoppages during the session, as well as Nelson PiquetJr hitting the wall at the end of turn 6.
Start of the session
As the green light appeared at the end of the pit lane there was a stream of activity as all the cars entered the circuit at the same time.
During the full course yellow simulation, Daniel Abt stopped in the tunnel on the exit of turn three, but he was able to get going again fairly quickly.
Abt later went off at turn one after the car understeered onto the runoff area, but again the German driver was able to get back on track.
Nelson Piquet Jr was the first driver to hit the wall. The Brazilian lost the rear end and slid into the wall. He was able to keep going without too much damage.
Mitch Evans caused a red flag after his Jaguar car stopped at turn nine and was unable to get going.
After 20 minutes of the session, Nick Heidfeld was leading the pack by a tenth of a second from Nico Prost with the two NEXTEV drivers in third and fourth.
End of the session
The driver’s confidence levels started to increase in the closing stages of the session as drivers started to find three-quarters of a second as Rosenqvist went fastest with 10 minutes of the session remaining.
In the final few minutes, Prost jumped to P1, but he wasn’t there for long as Buemi moved to first with a lap time that was five-tenths quicker than Prost.
