Jakarta E-Prix: Vergne beats da Costa in all-DS Techeetah pole battle

In a one-sided finale Vergne put 0.817s over da Costa, setting a 1m08.523s as da Costa endured a wayward lap - arguably losing his shot at pole with a slide at Turn 2 and confirming the result by lighting up the tyres in the final corner.

Vergne put three tenths over Mitch Evans to book his place in the final, easing the gap open over the opening pair of sectors before finishing the job against the Jaguar driver by doubling his advantage in the final sector.

Da Costa cleared Edoardo Mortara in their semi-final, jumping on the Venturi driver's slide through Turn 1 and using it to build a healthy advantage, which was four tenths to the good by the end of the lap.

Evans breezed past championship leader Stoffel Vandoorne in their bout, grabbing a gap of four tenths as soon as the opening corner and largely retaining that advantage throughout, save for a twitch at Turn 12 which allowed Vandoorne to claw back a tenth.

Vergne then pipped past Pascal Wehrlein in a closely contested quarter-final; the Frenchman held the advantage through the first sector, but Wehrlein pulled two tenths back to lead the way by the close of sector two.

But Vergne rallied as Wehrlein endured a lock-up, which moved the duel in the favour of the Techeetah racer.

Mortara found two tenths over Jake Dennis to progress to the semi-finals, holding a 0.075s advantage through both of the opening two sectors before finding more time at the end of the lap to put the Avalanche Andretti driver onto the sidelines.

In the last quarter-final, da Costa routed Sebastien Buemi with a lap over eight tenths clear of the Season 2 champion - grabbing the fastest lap time among the
