With track conditions different to Saturday, the majority of the drivers were fast to get out onto the damp Tempelhof Airport Street Circuit for some early laps on Sunday morning.
After only a matter of seconds, René Rast stopped on track and attempted a full power re-cycle to try and get moving again. His team-mate Jake Hughes battled to keep the car moving forward in a straight line, having to make multiple corrections as he struggled to get up to speed
Nick Cassidy was another driver that ran wide but he manage to keep the car out of the wall before the red flag was deployed to help move Rast’s car after the was unable to get moving again.
ABT Cupra’s Robin Frijns was fastest when the red flag was flown, with his team-mate Nico Müller in second and Avalanche Andretti’s André Lotterer in third.
With around 21 minutes remaining of the session, the cars were able to return to the circuit.
At the halfway point of the session, it was Lotterer who was fastest, 0.057 seconds faster than Oliver Rowland (Mahindra) in second place.
Yesterday’s second-place finisher Sam Bird (Jaguar TCS) moved up to the same spot on the leaderboard in this session, before Frijns went 0.080 seconds faster than him, still 0.103 seconds behind Lotterer out front.
Down the rear of the field, Norman Nato (Nissan) was the slowest of the drivers that were able to set a lap time, 2.814 seconds off the pace at the top of the standings.
Frijns then set an even better lap as he moved above Lotterer, going 0.218 seconds faster than the German driver.
Dan Ticktum (NIO 333) produced an incredible save to keep the car out of the barriers – minus a little tap – before drifting down the straight as track conditions remained damp as Lotterer returned to the top of the leaderboard, with Müller then going faster by 0.347 seconds with around four minutes left on the clock.
As the chequered flag came out, the drivers out on track went for one final flying lap, shaking up the leaderboard ahead of the qualifying session in only a matter of hours.
Saturday’s race winner, Mitch Evans (Jaguar TCS), was fastest in Free Practice 3, ahead of Lotterer and Tickum, with 02.67 seconds between the top three.
