Nico Rosberg has dominated the first day of the Belgian Grand Prix at Spa-Francorchamps. The German set the fastest time in first free practice and lowered the bar to a 1:49.385 in the second session. The gap to team mate Lewis Hamilton was three tenths. Rosberg had a scary moment though, when his right rear tyre exploded on the way to Blanchimont. He kept his car out of the barriers, which can't be said of Marcus Ericsson, who crashed in Turn 11.
