for the full Italian Grand Prix FP1 times
Mercedes has stamped its mark on proceedings in first free practice for the Italian Grand Prix, with Lewis Hamilton and Nico Rosberg a clear 1-2 at Monza.
Making use of an upgraded Mercedes engine this season, which has been revised with use of all seven of its in-season development tokens, Hamilton and Rosberg quickly set about establishing themselves out front and remained there until the chequered flag.
Hamilton was the faster of the two by a fair margin, his lap of 1min 24.670secs almost half-a-second faster than main title rival Rosberg.
With several drivers typically finding the limits of the brakes into the chicanes as the circuit found grip, Sebastian Vettel suffered an innocuous spin at Rettifilo but was still third fastest, albeit a distant 1.5secs off the top spot.
Keen to build on its best result of the season in Belgium, Force India hit the ground running in positive fashion with the newly re-signed Nico Hulkenberg in fourth and his team-mate Sergio Perez in fifth, while Kimi Raikkonen followed up in sixth despite complaining of brake problems.
Facing grid penalties this weekend for engine changes, Daniel Ricciardo was still a solid seventh fastest for Red Bull as the only Renault-powered car in the top ten, ahead of the two Williams' of Felipe Massa and Vatteri Bottas, while Pastor Maldonado ended up tenth in the best of the Lotus'.
Elsewhere, it was a tough start to the weekend for Toro Rosso, with Max Verstappen down in 14th, while team-mate Carlos Sainz managed just six laps before spinning into the gravel trap at the Parabolica early on in the session, forcing out the red flags for a time.
Faster than the Manors only, McLaren-Honda's Fernando Alonso and Jenson Button were 17th and 18th respectively, 3.3secs and 3.7secs off the ultimate pace.
