The Briton pulled out a margin of more than two tenths in the opening sector during the final qualifying duel before Maserati MSG’s Guenther pulled half of the deficit back in sector two.
The margin came down further in the final sector but Rowland held on to claim his second Formula E pole of the season by just 0.021s with a 1m19.023s.
A 1m18.855s which proved to be the fastest lap from the entirety of qualifying had ensured Rowland progressed to the final at the expense of Edoardo Mortara, as the Mahindra driver fell short by 0.226s.
An error-strewn lap cost ERT’s Sergio Sette Camara as he never troubled Guenther in their semi-final bout, finishing more than two seconds behind at the line.
A small mistake in the opening sector meant Pascal Wehrlein lost more than four tenths against Guenther in their quarter-final duel and although the Porsche driver reduced the deficit, he still missed out by three tenths.
Sette Camara was never headed in his battle against Abt’s Nico Muller, as he finished nearly six tenths clear to progress to the semi-finals.
A scruffy lap meant reigning champion Jake Dennis was slower than Mortara in all three sectors of their quarter-final duel, as the Mahindra driver posted a 1.19.008s to finish three tenths clear.
Mitch Evans’s quarter-final duel almost ended in disaster as the Kiwi glanced the wall through the fast right-hander of Turn 9 and which ultimately cost him in his battle against Rowland.
Evans initially missed out on progressing to the duels by half a tenth after finishing the opening qualifying group in fifth.
The Jaguar driver, who is set to make his 100th race start later today, finished 0.333s behind pacesetter Rowland, with Mortara, team-mate Nick Cassidy and Dennis also setting faster times.
