Toto Wolff: "I run a successful F1 team but that's nothing compared to what other people have achieved..."

He's presided over one of the most successful F1 teams of all time - and had to manage one of the most heated rivalries in history. So what exactly makes Mercedes chief Toto Wolff tick?

On this week's episode of Beyond The Grid, presented by Bose, the thoughtful Austrian lifts the lid on running a team - including dealing with the 'volcano-like' relationship between Lewis Hamilton and Nico Rosberg - gives a welcome update on colleague Niki Lauda's health, and tells Tom Clarkson about his truly remarkable journey to F1 via the business world after losing his father at a young age.
