Lucas di Grassi set the pace in Free Practice 3 ahead of the second Berlin E-Prix to take place on the Reverse Tempelhof circuit.
The Brazilian driver set a 1m06.732s to top the timesheets but it was a competitive session, with the top six covered by less than a tenth of a second.
Andre Lotterer was second for Porsche Formula E ahead of BMW i Andretti Autosport's Maximillian Guenther, Jagua Racing's Mitch Evans, Alex Sims in the other BMW and Antonio Felix Da Costa in the DS Techeetah.
Sims will be going into qualifying knowing he has a 20-place grid drop as the BMW team need to change his battery ahead of the race.
Unfortunately, BMW i Andretti Motorsport is forced to change the battery pack at the #27 BMW iFE.20 driven by @AlexanderSims. This results in a drop of 20 grid positions for today's race.#RacingBeyond #UnitedinRacing #BerlinEPrix #ABBFormulaE #SeasonSixFinale @FIAFormulaE pic.twitter.com/NlzeIQ0S66— BMW Motorsport (@BMWMotorsport) August 6, 2020
