From champion to F1 retiree
More rivals than teammates
Their bitter rivalry has been played out not only verbally, but also out on the track. The two got into a crash, which forced Hamilton to retire from the Belgian Grand Prix in 2014. In 2016 they've had two collisions, one in Barcelona (pictured here), which forced both to retire, and at the Austrian Grand Prix, which caused Rosberg to fall back to fourth place.
