Jaguar Brazil Racing’s Caca Bueno claimed his fourth pole position of the season in Berlin, beating team-mate Sergio Jimenez by 0.166s.
The two Brazilian drivers were the only Pro class racers who found improvements in the closing stages of the 30-minute session, while a late fast lap from Yaqi Zhang put him on Pro-Am class pole.
Bueno set the early pace ahead of Simon Evans, Jimenez and Bryan Sellers. The Brazilian was two-tenths of a second quicker than Evans at the halfway mark, but there was still time to be found at Tempelhof.
In the final 10 minutes of the session, Jimenez jumped up the order, his time just 0.036s behind his team-mate, but Bueno would improve again on the following lap. He lowered the benchmark to 1m26.672s, ending the session 0.166s ahead of Jimenez.
Evans finished third quickest, 0.336s behind Bueno, with Sellers and championship newcomer Adam Carroll completing the top five.
Pro-Am class leader Bandar Alesayi spent much of the session top of his class, but dropped behind Yaqi Zhang not long before the chequered flag.
Celia Martin was eighth overall, and third in class, ahead of Katherine Legge, who only completed a handful of laps and finished 0.236s behind the closest Pro driver.
Ziyi Zhang was 10th quickest, with Ahmed Bin-Khanen and guest driver Jens Dralle completing the order.
