Business F1 Top 20 Petrolheads: Roger Penske, Absolute Dedication

Roger Penske dominates American racing like no one else before him. He does not only run successful racing teams, but also owns the IndyCar series and the legendary Indianapolis circuit. He manages a giant group of companies with annual sales of nearly $40 billion, from truck rentals to car dealerships. Despite the big company business, he is fully committed to racing and can be seen almost every weekend at a racetrack supervising his many teams and drivers: Representing the very image of passion for motorsports. Like Bernie Ecclestone, the man who made Formula One big, Penske started out by trading used cars and has experienced it all: From driver, team owner to the Formula Indy, the world's oldest racetrack in Indianapolis, and everything in between.

Ecclestone and Penske have made fortunes of comparable size, worth several billions of dollars of value. They both own jets and yachts and yet they are equally unaffected by their wealth. They can be easily approached in racing paddocks around the world. Ecclestone, being seven years older, has already retired, but Penske probably never will: He loves the game too much. While Penske built a huge automotive conglomerate, Ecclestone focused solely on racing and made his money doing business.
