"There will be a lot of new things this season, but I am definitely looking forward to it. We have a new generation of world rally cars, and a new team - it's certainly an exciting time," said Ogier.
"There's not long before we line-up at the start of Rallye Monte-Carlo and we've not had a lot of seat time with the Ford Fiesta WRC, but we'll give it our best to be ready. We're aware of the challenges, and I can see how hungry Malcolm Wilson and his team are for success.
"It's funny to think that just a few months ago I was sitting at a motorsport forum at Wales Rally GB saying how nice it would be to work with him one day. I had no idea at the time that it would come quite so soon, but here we are!
"I'm looking forward to working with M-Sport, and we'll certainly be aiming to return them to the top-step of the podium!"
Wilson, M-Sport Managing Director, added: "We go to Rallye Monte-Carlo with the number one on the door of the Ford Fiesta WRC and the strongest driver line-up we have had in years. To say we're excited about next season is an understatement. We believe that we have produced an exceptional car, and we are in the best possible position ahead of this exciting new era.
"I've made no secret of how much we wanted to work with Sebastien and Julien, and it is fantastic to welcome them to the team. We have worked extremely hard to secure them, and they believe that the Ford Fiesta WRC is the car with which they can best defend their championship."
