Ex-FIA's Marcin Budkowski confirmed at Renault
The signing has caused for concern among rival teams.
Renault has confirmed the signing of Marcin Budkowski in the role of Executive Director, who will oversee all 'chassis development and production activities'.
Cyril Abiteboul, Managing Director Renault Sport Racing said: "There have been a lot of positive changes these last few months at Renault Sport Racing with an accelerated expansion at Enstone.
"The restructuring of our engine deployment from Viry with the supply of two top customer teams for 2018, three titles in a row in an increasingly competitive Formula E championship and other motor racing categories, and the arrival of new strategic partners.
"All of this is happening in a context where the seasons are longer and more intense. It was clear that the Renault Sport Racing management structure needed reinforcing.
"Marcin’s mission will be to continue the strengthening of Enstone to enable Renault to join the top Formula 1 teams by 2020, through relying on the proven personnel of the likes of Bob Bell, Nick Chester and Rob White. Marcin’s arrival is excellent news and further proof of our determination to achieve our goals.”
Budkowski has enjoyed spells with several Formula 1 teams since 2001, including Ferrari and McLaren before joining the FIA as technical and sporting co-ordinator - which he left ahead of the Malaysian Grand Prix.
The role with the governing body gave him special access to details of all the teams' current and future developments. And with only three months of gardening leave, Renault's rivals were left red-faced with the move, fearing he could help the French manufacturer with details which will help the team to catch up with the likes of Mercedes, Ferrari and Red Bull.
As per his original leave norms, Budkowski was to start with Renault in January 2018, however, Abiteboul revealed in the press conference that the on-going discussions with the FIA could result in Budkowski joining the team in April - which effectively doubles his three months leave to six.
