Closely behind Rosberg was Kimi Raikkonen in the Lotus setting the second fastest time after 44 laps of running.
Fernando Alonso’s first taste of the F138 saw him set the third fastest time on the medium tyre. He managed 110 laps on Tuesday, the most of any driver.

The first outing of the new Williams FW35 saw Pastor Maldonado set the fifth fastest time, completing 86 laps. His fastest time came on a soft set of tyres.
Behind hime Daniel Ricciardo set the sixth fastest time in the Toro Rosso, showing that the STR8 could be one of the strong challengers in the midfield.
McLaren’s Sergio Perez could only manage to set the seventh fastest time ahead of Force India’s Paul di Resta in eighth.
Esteban Gutierrez set the ninth fastest time in the Sauber after causing the first red flag of the day after running low on fuel.
Max Chilton set the 10th fastest time for Marussia whilst Charles Pic set the 11th fastest time for Caterham.
Whilst testing times should not be taken as a true gauge of the cars relative performance, the start of the second pre-season test should help to establish a potential running order for Australia.
Pre-season testing continues in Barcelona tomorrow where Lewis Hamilton, Nico Hulkenberg and Valtteri Bottas will take over the driving from their respective teammates.
