Williams recently stated they aren't happy with the partnership between them and Mercedes. They said the engine is not working in the car. Williams refuses to buy Mercedes gearboxes for better peformance. Williams already had talks with Renault about a deal for next season and think it will work better for the car, Williams already worked with Renault and won many races and championship and driver titles.
