Envision Racing’s Cassidy was fastest in the first and second sector during the final duel against his fellow Kiwi, putting him more than two tenths up on Evans.
But a blistering final sector ensured Jaguar’s Evans took pole position, and more importantly, denied Cassidy three points in his bid to overthrow Dennis at the head of the standings.
Evans will start sixth for this afternoon's race due to a five-place grid penalty he earned at the previous round in Rome for colliding with Cassidy, which meant neither scored points and they entered the London E-Prix double-header weekend 24 and 44 points respectively behind Dennis.
Cassidy, who will start first alongside Dennis, was handed a spot in the final after Envision Racing team-mate Sebastien Buemi took to the escape road at the Turn 10 chicane, despite being marginally faster in the opening sector.
Andretti Autosport’s Dennis had been eliminated in the earlier semi-final after posting a 1m10.806s which was nearly four tenths slower than Evans, but the championship leader is still set to start second after Evans’ penalty.
Cassidy comfortably beat Porsche’s Pascal Wehrlein by more than half a second in their quarter-final duel, while Buemi progressed through to the same semi-final having set the fastest lap across the entirety of qualifying against NIO 333’s Dan Ticktum, posting a 1m10.404s.
Evans blitzed all three sectors to finish sixth tenths clear of DS Penske’s Stoffel Vandoorne in the first quarter-final duel.
Dennis set a time almost identical to Evans’ best in the same segment of qualifying as he beat McLaren’s Rene Rast by almost four tenths to progress to the semi-final.
