United States Grand Prix – Lewis Hamilton completed the second free practice session as the fastest driver, but times were mostly irrelevant in the wet-weather session.
The rain continued to fall in the second free practice session, with the Circuit of the Americas seeing no track action for the first 45 minutes.
With the rain easing off in the second half of the session, drivers started to venture out of the pits for a few laps on intermediate tyres, which they were preserving for a potentially-wet qualifying day.
Hamilton was on track for three laps, but still set the fastest lap by more than a second with a 1:48.716, beating an impressive showing from Toro Rosso’s Pierre Gasly and his future Red Bull team-mate Max Verstappen.
In a session of mixed results, McLaren’s Fernando Alonso finished fourth ahead of Renault’s Nico Hulkenberg and Toro Rosso’s Brendon Hartley.
The two Ferraris of Kimi Raikkonen and Sebastian Vettel were down in ninth and tenth, around five seconds off the pace in a mostly-unrepresentative practice day.
Hartley and McLaren’s Stoffel Vandoorne completed the most running after they were both benched for free practice one to give test and development drivers track time.
Five drivers didn’t bother setting a time; Carlos Sainz (Renault), Daniel Ricciardo (Red Bull), Kevin Magnussen, Romain Grosjean (both Haas) and Valtteri Bottas (Mercedes).
Following the red flag in FP1, Vettel learned immediately after FP2 that he had been handed a three-place grid penalty for driving too fast under the red flag conditions.
