Lucas di Grassi topped the timesheets in the final practice session of the first Berlin E-Prix double-header, leading the way for Audi Sport Abt Schaeffler.
In the opening stages of the 45-minute window, it was GEOX Dragon’s Sergio Sette Camara who initially topped the timesheets, completing a 1:07.904s run using the 235kW Attack Mode.
The 22-year-old rookie, however, was soon toppled by championship leader Antonio Felix da Costa who improved by 1.083s with 23-minutes remaining.
Di Grassi’s run – a 1:06.732s lap – saw the Season 2 champion shoot to the top in the dying stages, displacing BMW’s Alexander Sims by 0.032s after the Briton previously bettered da Costa’s efforts.
Andre Lotterer emerged as di Grassi’s nearest challenger, 0.009s down for Porsche while Maximilian Guenther – who was disqualified from Race 1 after finishing in eighth place – was third.
Jaguar Racing’s Mitch Evans took the fourth fastest time as Sims was fifth in the second BMW. Da Costa meanwhile completed the top six, with only 0.089s covering the first quarter of the field.
After his early efforts, Sette Camara fronted a 7-11 result for the Penske-backed GEOX Dragon squad as team-mate Nico Muller narrowly missed out on the top 10.
Reigning back-to-back champion Jean-Eric Vergne was eighth in the second DS Techeetah, 0.129s shy of first place while Oliver Rowland was the lead Nissan e.dams driver in ninth.
Stoffel Vandoorne completed the top 10 for Mercedes EQ. Daniel Abt was the slowest driver of the session in 24th, some two-seconds down on his former Audi team-mate after struggling under braking in his NIO 333 car.
Only one second covered the top 23 in the session.
