Mercedes again led the way in the third and final practice session. Nico Rosberg set the pace with a lap of 1 minute, 29.385.
Lewis Hamilton was going even quicker on his soft tyre run, but made an error and abandoned the lap. But overall, both drivers look extremely strong, and the team finished up early having done all they wanted to do.
Valtteri Bottas also finished early, but not by choice. The Williams man took no meaningful part in the session after a gearbox failure. The box will be changed, so he faces a five-place grid penalty after qualifying.
Romain Grosjean too had a bad day, despite putting in a decent number of laps. The Frenchman seems to be growing increasingly irate with his problematic Lotus.
Early in the session he angrily called the situation "unbelievable" (on team radio) and later on roared "nothing is solved!" when his race engineer requested he change torque map to charge his battery.
And teammate Pastor Maldonado stopped on the track in the session's closing minutes. With only two hours to fix the car, the team face a battle to get him into qualifying.
But it was good news at Caterham. Marcus Ericsson was out early as the team finally got some laps on the board. Kamui Kobayashi's lap of 1:34.413 doesn't look much, but it ends any worries Caterham may have had about the 107-percent rule.
In the fight behind Mercedes, it still looks close between Williams, McLaren, Ferrari, Red Bull and Force India.
Many drivers made errors into Turn 9, the chicane at the back of the circuit, where a strong tailwind played havoc with braking points. Kevin Magnussen and Jenson Button were among those caught out.
And mistakes were common elsewhere too. The drivers are by no means entirely used to their new cars.
So we go into qualifying with a little more idea of who is where, but nothing is crystal clear.
That includes the sky. Rain is possible, and it might just ruin Mercedes' party.
