Jaguar's Evans and Porsche rival Pascal Wehrlein largely dominated the majority of the 29-lap race at the Shanghai International Circuit, each leading for large portions around the truncated grand prix layout.
Having taken the lead just past the halfway point, Wehrlein noticeably upped the pace and defended his lead at various points around the lap.
But locking up into the Turn 6 hairpin on lap 23 allowed Evans to get a switchback on the exit which gave him the lead.
Just two laps later, Wehrlein was back to the front but only after cutting the Turn 11 left-hander through the final sequence of corners after running side-by-side with Evans.
Wehrlein maintained the position for the remaining laps but came under heavy pressure from Evans and the second Jaguar of Nick Cassidy.
Heading onto the last lap, Evans swept to the outside through the long left of Turn 1 to take the lead and the win on-the-road, but the Kiwi remains under investigation for allegedly leaving the track and gaining an advantage.
