Sebastien Buemi topped the first practice session in Berlin, followed by Renault e.dams team-mate Nico Prost.
The two drivers were the only ones to set a lap under 1m09 seconds, with Buemi over five tenths faster. The 28-year-old left it to the final minutes to set a fast lap on the new circuit at Tempelhof.
The red flag came out in the first half of the session when Mitch Evans stopped on track and had to be assisted back to the pits. He found himself in seventh after the chequered flag came out, while his Jaguar team-mate Adam Carroll rounded off the top 10.
The only major incident in first practice came from Nelson Piquet Jr, who hit the outside wall coming out of Turn 5 into the straight. The Brazilian was able to get back to the pits, although the contact will be disappointing.
Felix Rosenqvist was the fastest of everyone else, with the Mahindra team looking strong again this weekend. Both he and Nick Heidfeld were running near the top for the majority of the session, although Heidfeld looked to have some issues after stopping multiple times.
DS Virgin Racing also look competitive, with Jose Maria Lopez and Sam Bird taking fourth and fifth respectively. Lopez is looking to build on his second place finish at the last ePrix in Paris, with Bird will be looking to get himself higher in the drivers’ championship standings.
Jean-Eric Vergne finished the session in sixth, while his new team-mate at Techeetah and former Venturi driver Stephane Sarrazin down in 13th, although the Frenchman will be getting used to his new car.
Buemi’s closest championship rival Lucas di Grassi was ninth, which he will need to build on during the day to have the best chance to close the gap in the overall standings. His team-mate Daniel Abt was one of the quickest drivers at the start of the session, although fell down to 12th.
After signing permanently for Venturi following the departure of Esteban Gutierrez to IndyCar, Tom Dillmann had a disrupted first practice session in Berlin. The 28-year-old had gearbox issues with the car intended to be used and had to wait for the second car to be ready before going out on track.
