There will be no more Sebastian Vettel-"Rocky" exchanges from the 2015 season after Red Bull revealed the German will get a new race engineer.
Vettel and Guillaume "Rocky" Rocquelin have had some memorable radio conversations over the past five years, but the Milton Keynes squad have confirmed that Gianpiero Lambiase will take over from Roquelin next year.
Vettel and Rocquelin started working together when the German moved to Red Bull in 2009 and they won four consecutive World Championships together.
Red Bull, though, are set for a technical revamp next year and Rocquelin will take up a new senior role.
Lambiase will work together with Vettel from next year with the Italian confirming he will leave Force India where he is currently working as Sergio Perez's race engineer.
