4. Keke And Nico Rosberg
Here, the things get interesting. This is a tough one. Nico is the clear winner on paper. Both of the Rosbergs won a world championship, but Nico is far better than his dad in every other measure.
He won 23 races, while his dad only won five. Nico scored 30 pole positions to his dad’s five, and had 20 fastest laps to his dad’s three. The most staggering comparison are total points, 1594.5 to 159.5, although the scoring systems were different. Worth considering is the fact that Nico had a dominant Mercedes car, while his dad had to work much harder for his success.
Ultimately, Nico is the winner, as managing all those wins and other stats when your teammate is none other than Lewis Hamilton is more than impressive. He had the same Mercedes as Nico, so you do the math.
