Wehrlein had started the race third and went later than those around him with his 50kW, all-wheel drive ATTACK MODE boost coming after his PIT BOOST stop.
The overlap allowed the Season 10 World Champion to pull some eight seconds on those behind heading into the closing stages of the race.

From there, he was able to manage the gap to Mortara - the Mahindra driver recovering from a wheelspinning start which saw him slip from pole to fifth by the end of Lap 1. Mortara made his way up the order with a late ATTACK MODE charge through the field to second spot - though he and the team felt the win had been on, barring that poor getaway.
Those who activated ATTACK late seemed best place as the race reached its climax. Evans was next to prove as much as he sliced his way through the top 10 to an eventual third at the chequered flag and back-to-back podiums.
Nico Mueller (Porsche) rounded fourth ahead of the second Jaguar of Antonio Felix da Costa and Citroen Racing's Nick Cassidy - another of the late chargers - who rounded out the top six having qualified only 13th.
Wehrlein's win and fastest lap yeilded a 26-point haul and propelled the Porsche driver to the top of the Drivers' standings - 64 points to Cassidy's 48. Porsche head the Teams' 109 plays Mahindra's 59 points. The Stuttgart marque sits top of the Manufacturers' on 125 points to Jaguar's 81.
We're back tomorrow evening for Round 5 of 2025/26 under the lights in Jeddah.
As it happened...
After Nyck de Vries stricken Mahindra was removed from the initial grid line-up the pack fired away to Turn 1 with Edo Mortara bogging down in a huge burnout - losing P1 immediately as the front-runners swamped the Swiss' car.
Guenther happily accepted the invite to take the lead into Turn 1 while Nato, Barnard and Wehrlein followed - Mortara finding himself fifth just ahead of the second Porsche of Nico Mueller. A Full Course Yellow followed on Lap 2 after Pepe Marti swept across the nose of the unfortunate Zane Maloney - whose Lola Yamaha ABT came off worst, with race-ending damage requiring a Safety Car.
Lap 4 and we were green and racing again - Guenther leading the field away.
Wehrlein managed to make some forward progress with a move on Barnard for third heading down to the final chicane at the end of that lap on the restart.
Nato swept into the lead on Lap 6 and from there, the race settled into a fast-paced rhythm with energy becoming less critical thanks to that Safety Car, with the PIT BOOST window - where cars take on a 30-second jolt of extra energy - looking like opening on Lap 15.
Wehrlein pinched second from Guenther into the Bus Stop chicane on Lap 14 as the field compressed to within 7.5 seconds, and the PIT BOOST window approached.
The Porsche driver then hit the front at Turn 13 with the pace picking up. Guenther was the first to jump for his mandatory 50kW, all-wheel drive ATTACK MODE boost on Lap 15. Lap 16 saw Rowland and Eriksson peel off into the pits for their stop - the Swede overshooting his pit box in his haste.
The end of Lap 16 saw another half dozen take to the pits for their stop. As it stood on Lap 17, Barnard looked to be the provisional leader - though two thirds of the pack were yet to take to the pit lane.
Out front, Wehrlein and Guenther were scrapping for P1, with Guenther making it by as Wehrlein slipped into the pits for his PIT BOOST stop at the end of Lap 18.
The provisional lead, of those who'd stopped, switched hands to Jake Dennis - with Barnard jumping for ATTACK MODE. However, when it all shook out, it was Guenther who was able to retain the lead - Porsche's Werhlein second and yet to take ATTACK.
The German made that advantage count as he activated his 50kW, all-wheel drive boost to pass Guenther on Lap 20. Four minutes in that heightened 350kW state for Wehrlein and the race looking to be in his hands.
That early jump for ATTACK cost Guenther - with the German sliding further down the order as Dennis and da Costa made it by for second and third, then Ticktum making it through for fourth on Lap 22.
Ticktum defended hard to fend off Barnard but with the DS on the ATTACK MODE overlap, the Brit was powerless - Barnard making it by for fourth across the start/finish on Lap 23.
Wehrlein drew out a five-second lead on Dennis with da Costa, Barnard, Ticktum and Guenther the top six as it stood on that tour - all having taken their ATTACK MODE.
Barnard made it by Nato for third at the hairpin despite running in that standard 300kW mode - the latter having made his way up the order in ATTACK on Lap 25. Lap 26 saw Mortara making use of his late ATTACK MODE activation - slicing by Nato for fifth and Barnard for P4. Come Turn 13 and the Mahindra driver had recovered to second spot - hunting Wehrlein, who was some seven seconds clear out-front.
A late ATTACK looked to be the way forward. Evans was next to slice through the field - making it as far as third come Lap 28.
Cassidy was next to move but could only make it as far as sixth spot at the end of his 50kW boost on Lap 31.
Wehrlein had it all in-hand in P1, with Mortara held at arm's length as the German took the chequered flag.
