Three-time Formula One world champion Niki Lauda has died at the age of 70.
The former racing driver "passed away peacefully", his family said on Monday in a statement reported by the Austria Press Agency.
Mercedes team principal Toto Wolff led the tributes to the team's chairman saying his death "leaves a void in Formula One".
He said: "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.
"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."
