The world of motorsport has paid tribute to Niki Lauda following the news of his death on Monday night.
The three-time world champion was an inspirational figure in the sport and had ties with a large number of teams and drivers.
He won two titles with Ferrari in 1975 and 1977 before returning from retirement to win a third with McLaren in 1984. He went on to become chairman of the Mercedes Formula One team, and his business partner and close friend Toto Wolff was among those who paid tribute to Lauda on Tuesday morning
Toto Wolff, Mercedes team principal
"First of all, on behalf of the team and all at Mercedes, I wish to send our deepest condolences to Birgit, Niki's children, his family and close friends.
"Niki will always remain one of the greatest legends of our sport -- he combined heroism, humanity and honesty inside and outside the cockpit. His passing leaves a void in Formula One. We haven't just lost a hero who staged the most remarkable comeback ever seen, but also a man who brought precious clarity and candour to modern Formula One. He will be greatly missed as our voice of common sense.
"Our Mercedes team has also lost a guiding light. As a team-mate over the past six and a half years, Niki was always brutally honest -- and utterly loyal. It was a privilege to count him among our team and moving to witness just how much it meant to him to be part of the team's success. Whenever he walked the floor in Brackley and Brixworth, or delivered one of his famous motivational speeches, he brought an energy that nobody else could replicate.
"Niki, you are quite simple irreplaceable, there will never be another like you. "It was our honour to call you our chairman -- and my privilege to call you my friend."

My buddy, I am struggling to believe you are gone. I will miss our conversations, our laughs, the big hugs after winning races together. It's truly been an honour working alongside you over these past 7 years. I wouldn't have even been in this team if it wasn't for you. God rest your soul. Thank you for being a bright light in my life. I'll always be here for your family should they ever need me. Love you man. Your friend always, Lewis #oneofakind #gonetoosoon #youliveoninourhearts #restinpeace 📷 @motorsport.images

Oh no. The man himself is no longer with us 😢. A great human being, determined, relentless, talented, passionate, forthright, honest, humble, and great company. Living on borrowed time since his awful crash in 1976, he certainly made the absolute most of that gift. RIP Niki https://t.co/WRSsBL3TUV— Martin Brundle (@MBrundleF1) May 21, 2019
