Four-time world champion Sebastien Ogier is the highest profile casualty of Volkswagen's exit. The Frenchman had a contract for 2017 but is now left without a drive.
"Ogier now faces quite a difficult decision," Evans says. "He is married now and had his first child through the middle of this year. He struggled quite a bit this year - there were times this year where I could have seen him walk away mid-season. He struggled with the rules and the running order regulations. It has been a difficult year for him.
"He has always maintained that he doesn't want to chase Sebastien Loeb's record of nine titles - that is not what he is about.
"He has ambitions outside of the sport and he also wants a family life as well. Perhaps this offers him the perfect opportunity to go.
"If he stays, I could see him going back to Citroen. I'm sure Citroen could probably find some money for him.
"And if not, why not M-Sport? Just before Rally GB last week, he made a lot out of how he hadn't driven for Malcolm Wilson and how he would like to."
Evans doesn't believe this news will have any impact on Kiwi driver Hayden Paddon, who has a water-tight contract with Hyundai for 2017.
