The Jaguar driver was in contention for the win in Saudi Arabia as he battled Vergne and eventual race winner Jake Dennis in the early stages as the trio broke away from the pack.
Evans was leading when he took his first Attack Mode activation on lap four, one tour after polesitter Vergne had also gone through the activation zone.
But on rejoining the racing line the pair made contact and the loss of momentum meant Evans dropped behind Vergne.
“There’s a couple of things which annoyed me in the race. Obviously, the rejoin with the Attack Mode, Vergne pushed me into the wall,” Evans told Autosport.
“The next corner was essentially mine but with that contact, it gave him the momentum, how that wasn’t a penalty I don’t understand.
“If I back out of that and he’s got the intention to put me in the wall I’m hitting his right-rear [tyre] and he’s in the wall straight away. If he doesn’t make contact with me it’s my corner.
“There’s contact so it needs to be looked at and I think the approach from him was to put me in the wall.”
