F1: Vettel gets new engineer for 2015

Four-time Formula 1 world champion Sebastian Vettel will have a new race engineer next season, with long-serving Guillaume Roquelin moving to a new role within Red Bull.

Vettel and Roquelin, who is widely known as "Rocky," have worked together ever since the German joined the team in 2009. Their partnership has proved hugely successful, with them securing the last four world titles together.

However, ahead of the start of a new era at Red Bull as technical chief Adrian Newey steps aside for a new role, the outfit is to undergo a reshuffle of its technical staff. Red Bull sources have confirmed that Roquelin will move on from his race engineering role to a new senior position with the team, but will still attend grands prix.

Vettel's new race engineer will be Gianpiero Lambiase, who is currently Sergio Perez's race engineer at Force India.
