Mercedes’ Lewis Hamilton finished on top of the time sheets in the first practice session for the United States Grand Prix.

Hamilton finished on top with a time of 1:39.941. His team mate Nico Rosberg finished the session 0.292s slower than his team mate in P2 with a 1:40.233. McLaren’s Jenson Button was the little surprise of the session finishing in P3 with a 1:40.319, just 0.378s off Hamilton’s pace.

Daniil Kvyat in his Toro Rosso ended his session in P4 with a 1:40.887 while Kevin Magnussen in the other McLaren finished off the session in P5 with a 1:40.987.

The session was rather quiet with a few spins and some drivers getting caught out at turn 19 by running wide or getting too late on the brakes and locking up.

It was a rather anonymous session for Red Bull and Ferrari. Daniel Ricciardo had to cut his session short after the team found and issue with his engine. Sebastian Vettel had a fair amount of running out on track but struggled with the rear grip on his RB10. Vettel ended the session in P7 while Ricciardo could only manage P17 after 5 laps.

The two Ferrari drivers trailed new wings and evaluated new parts for the first part of the session. Fernando Alonso seemed to struggle with the rear of the car while Kimi Raikkonen just seemed out of sorts on track.

McLaren’s pace does look very promising for now. If they can keep up the pace we could be in for a very exciting qualifying session.

At the end of the session, a virtual safety car was trailed. Cars are given a delta time to stick to. This delta time has to be followed. At the end of the session/race two cars will be chosen at random and the data from their ECU’s analysed to determine if the driver did, in fact, adhere to the delta time.
