Michael Schumacher's former Ferrari race engineer Chris Dyer has joined the new Renault Sport F1 team as head of vehicle performance group in another big-name signing for the Enstone squad.
Having completed the transition from Lotus to Renault Sport over the winter, the new F1 squad was formally unveiled at a launch presentation in Pairs. As well as new driver Kevin Magnussen joining Jolyon Palmer and a host of new technical staff Dyer is the latest to make the switch to Renault for 2016.
The Australian first broke on to the motorsport scene with Holden in V8 touring cars in 1992 before moving into F1 with Arrows initially as a data engineer. Dyer then stepped up as race engineer at Arrows before leaving for Ferrari in 2001 where he helped Michael Schumacher claim his 2003 and 2004 F1 world titles as his race engineer before working with his replacement Kimi Raikkonen and helped him secure the 2007 F1 drivers' crown.
Dyer switched to chief track engineer for Ferrari in 2009 but was replaced by Pat Fry in 2011 after he was blamed for the call to pit Fernando Alonso to cover Mark Webber at the 2010 Abu Dhabi Grand Prix, ultimately handing Sebastian Vettel the championship.
In 2012, Dyer left the Italian manufacturer to become chief engineer for BMW's DTM efforts and now returns to F1 with Renault.
Ayao Komatsum, who has previously held a senior engineering role for the team, has left for the new Haas F1 squad.
