In a 43-lap thriller in Brooklyn, New York, Audi Sport Abt Schaeffler claimed the 2017/18 Formula E Teams' title with a 2-3 finish in the final race of Season Four while Jean-Eric Vergne claimed a fourth victory of the season.
In qualifying, Renault e.dams' Sebastien Buemi claimed a second consecutive pole position while Techeetah's Andre Lotterer and Vergne qualified in second and third on the grid, closely followed by Lucas di Grassi and Daniel Abt of the rival Audi team in fourth and fifth.
Securing a flying start from the second row, Vergne took the lead in Turn 1 on the opening lap, passing Buemi for first place with a diving move while Lotterer dropped down to third
After such a strong start for Techeetah, both Vergne and Lotterer were quicky under investigation for an alleged jump-start offence and while Vergne escaped penalty, Lotterer's race was hampered with a 10-second stop-go penalty which would prove to be a pivotal moment in the Teams' Championship.
After clearing Buemi on lap 5, Lotterer moved into second place before serving his penalty on lap 12 which promoted di Grassi into the podium places before the Season Three champion cleared his long-terms Swiss rival to move closer to Vergne who remained out in front.
Closing in on Vergne, di Grassi stuck to the rear of the Frenchman's car like glue while a battle for the fastest lap of the race erupted between the two Techeetah drivers and two Audis in a bid to maximise each championship scenario.
After failing to find a way past Vergne, di Grassi followed the leader into the pits on lap 24 and with the pair having near identical pit stop times, both rejoined in the same positions at the front of the pack.
Despite launching multiple dummy attacks on Vergne, di Grassi was ultimately unable to take the lead of the race to claim a third consecutive win in Season Four and instead settled for second place while Vergne took the chequered flag on lap 43 with a stunning display of defensive driving and flat-out racing.
With Abt standing on the final step of the podium, it was an Audi day in Brooklyn, with the German marque claiming the Teams' Championship against all odds after having a difficult start to the 2017/18 campaign, beating independent team Techeetah to the title.
Buemi was unable to emulate his performance from Race 1 and finished in fourth place for Renault while Felix Rosenqvist completed the top five for Mahindra to score his best result since the Punta del Este E-Prix.
Mitch Evans fronted a 6-7 finish for Jaguar Racing with inaugural Formula E champion Nelson Piquet Jr finishing in seventh place.
Nich Heidfeld finished in eighth place in the second Mahindra and was followed by Lotterer who fought up to ninth in a recovery drive after his progress was halted in the opening stages of the race through his 10-second penalty.
Sam Bird completed the top 10 for DS Virgin Racing, losing second place in the Drivers' Championship to Lucas di Grassi.
Outside of the top 10, Nico Prost missed out on a points finish in his final race for the French e.dams squad while Alex Lynn finished in 14th place in the second DS car.
Formula E's Season Four finale saw five drivers fail to see the chequered flag, with Venturi suffering from a double-DNF while Dragon Racing were a victim of bad luck, with Jose Maria Lopez suffering from a suspension failure while Jerome d'Ambrosio was collected in an accident between Luca Filippi and Antonio Felix da Costa. Filippi also retired.
