Formula 1 stars Lewis Hamilton and Valtteri Bottas defended a Mercedes one-two in second practice at the Spanish Grand Prix, easily clear of the Ferraris.
The United Kingdom born racer [Hamilton] was 0.09 seconds quicker than his partner but 0.310secs clear of the Ferrari of Kimi Raikkonen, who was 0.118secs ahead of Sebastian Vettel.
Red Bull's driver Max Verstappen and Daniel Ricciardo were next, looking as if they have sealed the gap to the top cars.
The first six were closed by less than 0.8secs, closer than so far this year.
Hamilton said after the session: "First practice was very, very good but in second practice the track changed and shifted quite a lot, so it was slippery and quite a lot slower for everyone - especially with the gusts of wind.
"It was massively challenging, but still fun nonetheless. The team has done an amazing job with the upgrades and the car is working just as we expected. It's been a much better start to the weekend for me than in Sochi, so I'm very happy."
Vettel said: "I'm not happy. Struggling a bit to find the rhythm, with the conditions, probably more myself than the car.
"I didn't get everything together but I can feel the car is quick so that's good. I am not worried. I am just not happy with how the day went. I wasn't always feeling as if I was captain on board.
"Sometimes somebody else was steering my ship but I hope tomorrow whoever that was will disappear."
