Jake Dennis, driving for Avalanche Andretti Formula E, won his first-ever World Championship with just 1 race to spare in London.
He was replaced by touring car and GT racer Kelvin van der Linde, who made his Formula E debut after testing for Audi in 2020.
André Lotterer missed the Jakarta double-header as he attended the 24 Hours of Le Mans test day held across the same weekend.
[69] The third generation of Formula E began in January in Mexico City with Lucas di Grassi taking pole position on his debut for Mahindra Racing ahead Andretti's Jake Dennis.
Di Grassi led away at the start, before the race was interrupted twice: ABT CUPRA's Robin Frijns ran into the back of Norman Nato's Nissan, putting them both out of the race and breaking Frijns' wrist, before Sam Bird's Jaguar stopped to bring out another safety car.
Dennis would take the lead off di Grassi on lap 12, building a gap before a third safety car was called when Edoardo Mortara lost control of his Maserati and hit the wall.
[70] At the Diriyah double-header, Kelvin van der Linde made his Formula E debut as a substitute for the injured Frijns.
Championship leader Dennis too had a great race, starting eleventh and managing to work his way up the order.
[71] Hughes took his maiden pole position for the second Diriyah race, ahead of Jaguar's Mitch Evans and his McLaren teammate René Rast.
The gaps were then nullified as a safety car was called when ABT Cupra's Nico Müller hit the wall on lap 27.
[72] The next round, the inaugural Hyderabad ePrix, saw Evans take pole position ahead of DS Penske's Jean-Éric Vergne.
Buemi came home third, before receiving a penalty that promoted Porsche's António Félix da Costa to the podium.
An early safety car because of Wehrlein crashing into Buemi saw Günther move into the lead, before Cassidy was next to take first spot.
As Frijns returned to ABT CUPRA from his injury, reigning champion Stoffel Vandoorne took his first pole position for DS Penske.
Buemi took his 16th pole position, a new Formula E record, but was beaten at the start by Ticktum rocketing from fourth on the grid into the lead.
[76] The second Berlin race saw a wet qualifying that ended with a surprise ABT CUPRA front-row lockout, with Frijns ahead of Müller.
The race was delayed because of protestors storming the grid, but when it got underway, the ABT CUPRAs were unable to keep up with the other leading cars and soon dropped back.
He initially led away from Fenestraz, before Evans took the lead from the pair after the first round of attack mode activations that saw Hughes drop down to fifth.
He overtook the three cars of Dennis, Wehrlein and Günther into the hairpin on lap four, before taking the lead from Evans during the second round of attack modes.
[78] Two drivers made their debut at Jakarta: David Beckmann as a stand-in for Andretti's André Lotterer, and Roberto Merhi to replace Oliver Rowland at Mahindra.
After briefly falling to fourth behind Vandoorne, Dennis quickly climbed back to second and remained there as Wehrlein's main threat.
These top three positions remained until the end of the race, while down in the lower reaches of the points, the two Jaguars collided again, forcing Evans to retire.
Championship protagonists Cassidy and Wehrlein had a battle further down the order that resulted in the former sustaining damage to his front wing, forcing him to pit for repairs and out of the points.
The high-speed nature of the track meant that energy saving once again had top priority, with drivers often lapping more than 10 seconds off the pace in the opening part of the race.
Cassidy, who had started tenth, steadily worked his way up the order to claim the lead shortly before the race was interrupted for a heavy crash after a brake failure for Müller.
Da Costa then took the lead and started showing more pace in the final part of the race, with only Cassidy and Dennis able to hold on to him.
As the race after the red flag was one lap longer than Andretti had initially expected, Dennis was then forced to conserve energy, dropping him behind Cassidy and Günther in fourth.
[83] The final weekend in London began with Evans taking pole position, but a 5-place grid penalty for his crash in Rome meant Cassidy started first.
Newly crowned champion Dennis cruised home to third in a race where, despite very tricky conditions, all 22 cars reached the finish line.
In London, Cassidy and Envision then gambled away their slim chances by trying to win both championships at the same time, while Dennis just had to keep consistent to secure the crown.
