Renault's former director of aerodynamics Dino Toso, lost his battle with illness on Wednesday and passed away peacefully at his home.
Toso, who was diagnosed with cancer in 2004, worked with the team up until June this year.
The Italian initially worked in the aerospace industry before joining BMW's GT programme in 1995 and then moving up to Formula 1 with Jordan in 1997. He joined Renault in 2000.
A statement from the Regie
paid homage to the 39-year-old:
"It is with great sadness that the ING Renault F1 Team confirms that former director of aerodynamics, Dino Toso, lost his battle with illness this morning.
"Dino was instrumental in building one of the sport's most successful aerodynamics departments, which helped the Renault F1 team win double drivers' and constructors' titles in 2005 and 2006.
"His contribution to the team, both through his results and his courage in the face of illness, are an inspiration.
"He will be missed enormously and the immediate thoughts of the whole team are with his family."
