| Lewis Hamilton |
Mercedes continued their 1-2 parade of the 2015 F1 season with Lewis Hamilton and teammate Nico Rosberg easily on top in the opening practice for the Brazilian GP at Interlagos.
Sebastian Vettel was the best of the rest, coming in third in his #5 Ferrari ahead of Daniel Ricciardo in the Red Bull with the upgraded Renault engine, and Kimi Raikkonen in the 2nd Ferrari to round out the top-5.
In his last race of his short career at Manor, Alexander Rossi again beat Will Stevens, with the duo both over four seconds down at the rear of the field in the year old slug of a car that Manor uses.
