Leading figures in Formula One have paid tribute to Sergio Marchionne on Wednesday following the announcement the former Ferrari chairman had died aged 66.
"We are deeply saddened by the passing of Sergio Marchionne," Formula One chairman and chief executive Chase Carey said. "He was a great leader of not just Formula 1 and the automobile world, but the business world overall.
"He led with great passion, energy and insight, and inspired all around him. His contributions to Formula 1 are immeasurable.
"He was also a true friend to all of us and he will be deeply missed. At this difficult time we extend our deepest sympathies to his family, friends and colleagues."
Marchionne took over the presidency of Ferrari in 2014 and helped rebuild the team to one capable of challenging for the world championship.
He was replaced at the weekend after complications from a shoulder operation left him unable to return to work.
"This is a sad day for all of us in F1. We have a lost a huge supporter of our sport, a fierce competitor, an ally and a friend," said Mercedes motorsport chief Toto Wolff.
"Our heartfelt sympathies are with Sergio's family and all at Scuderia Ferrari at this difficult time."
Williams and McLaren were among other teams to pass on their sympathies.
