WATCH: Leaders collide twice during a dramatic Race 2

David Schumacher and reverse polesitter Enzo Fittipaldi exchanged P1 between them for the majority of Race 2, but collided at the exit of Turn 2 with six laps to go.

Their collision gifted the lead to Matteo Nannini and Dennis Hauger, only for them to come together in the same place four laps later and hand Caldwell a first F3 win.

Take a look at the race-defining moments in the video above.
