Nico Rosberg ended the Austrian in-season F1 test as the fastest man, setting the fastest lap in what became a very productive day for all runners present.
The initially damp morning session was topped by Valtteri Bottas, however times didn't matter much, as even the Williams driver was busy focusing on aerodynamic validation for his team.
The busiest man of the day was Marco Wittmann. After a slow start to getting used to the car, he gradually upped his pace and finished the day 4th fastest. Wittmann thanked his F1 test debut to BMW by winning last year's DTM championship.
In general, there were no major incidents during the day, only Daniel Ricciardo came to a halt in the final hour, briefly creating a red flag situation.
