Championship leader Maximilian Guenther failed to win the race for the first time this season as his compatriot delivered a blistering qualifying lap to start at the front of the pack ahead of Mercedes Benz EQ's Stoffel Vandoorne who had started both previous races on pole.
Wehrlein soon left the rest of the grid in his wake as he comfortably cruised to victory ahead of Vandoorne and pre-race favourite Guenther of BMW i Andretti Motorsport who still leads the Championship by 20 points.
The unpredictable nature of the championship was restored before the race had even started, when Guenther only managed to qualify in sixth position, having won both of the championship's opening rounds as well as the pre-season test.
Guenther made the most of a chaotic first lap to fight his way up to third place but couldn’t maintain the momentum and was unable to close the gap substantially enough to mount a challenge to the top two, leaving his compatriot Wehrlein to secure a dominant victory ahead of Vandoorne.
Earlier in the day, Kevin Siggy had taken the first available chequered flag, after qualifying on pole and dominating from lights to flag in the ABB Formula E Race at Home Challenge 'Challenger Race'.
The Slovenian beat real-world racers such as Sophia Floersch and Alex Lynn to extend his lead at the top of the championship and take another step towards the title and the coveted prize of a drive in a real Formula E car when racing resumes.
Before then, the focus will be on whether the chasing pack can shrink Guenther's championship lead further as the ABB Formula E Race at Home Challenge returns for Round Four next Saturday 16th May at 15:30 BST
