Dietrich Mateschitz passed away without the Formula 1 world ever getting to know him, because his shunning of the limelight was so extreme. He did not do interviews, didn’t really mix with those outside his team, only attended the odd few races. Yet he will go down in history as one of the most influential and positive presences the sport has ever seen. Not only for his blockbusting F1 team but the sheer number of drivers his Red Bull development programme brought into the category over the years, not to mention the rebirth of the Austrian Grand Prix, something which would never have happened without his buying the old track near Zeltweg and his vision around it.
