Jakarta E-Prix: Vergne leads DS Techeetah's late Formula E FP2 sweep
Da Costa had only just cleared Jake Dennis from the top of the FP2 times, the 2019-20 champion logging a 1m07.993s to go quickest at the chequered flag, but Vergne put his car on top even later into the session to hammer home a clear Techeetah advantage.
As the mercury pushed 32 degrees C in time for FP2, the drivers had to intersperse their laps with tentative cooldown tours to ensure the tyres were not too punished by the escalating track temperatures.
This ensured that traffic proved to be a difficult factor to manage throughout the session, with a number of promising laps failing to yield consistent performance across all three sectors.
Lucas di Grassi was first into the 1m08s, logging a 1m08.750s to set an early marker - where he was followed into the same bracket by Nissan e.dams duo Sebastien Buemi and Maximilian Guenther.
The Brazilian driver was then dispatched from top spot by points leader Stoffel Vandoorne, who found a tenth and a half over the Venturi ace.
Sergio Sette Camara looked good to kick Vandoorne off the top, but a less successful final sector contrived to place the Dragon Penske driver in third, behind compatriot di Grassi.
Pascal Wehrlein then hustled his Porsche to the leading time, clocking a 1m08.410s to beat di Grassi's best lap from FP1 despite losing a smidgen of time in the final sector.
But it was then the turn of the NIO 333 pair to bask in the sun as Oliver Turvey shaded Wehrlein's time by 0.031s, but was immediately displaced by Dan Ticktum who scorched to a 1m08.338s.
As the session then ticked down into its final 10 minutes, Jake Dennis powered to the top of the timing boards with a 1m08.253s, but the Avalanche Andretti had to see off an assault from Edoardo Mortara and Mitch Evans.
